The DDR reserved area must much the one declared in the kernel device tree: at least 1 GB of RAM is required on the SoM to allow Cortex-M7 accessing the range 0x7E000000 - 0x7EFFFFFF. For some reason, Cortex-M7 is not able to access RAM locations below 0x60000000: SoMs with 512 MB of RAM are not suitable to use Cortex-M7.

The DDR reserved area must match the one declared in the kernel device tree: at least 1 GB of RAM is required on the SoM to allow Cortex-M7 accessing the range 0x7E000000 - 0x7EFFFFFF. For some reason, Cortex-M7 is not able to access RAM locations below 0x60000000: SoMs with 512 MB of RAM are not suitable to use Cortex-M7.


=== JTAG ===
The RPMSG area is located at 0x40000000: all SoMs allow Cortex-M7 accessing the RPMSG area.

-->The SDK allow linking using 2 different memory types: DDR, TCM.
-->To allow Cortex M7 accessing shared resources without experiencing Linux kernel conflicts, a dedicated device tree must be loaded, containing '''m7''' label in the name, using the fdt_file environment variable in U-Boot.


Here is available a short summary of memory areas used by Cortex-M4 as described in related linker file.
This device tree disables some of the base device tree nodes in order to avoid conflicts between the main processor and Cortex M7.

All linker files are locate in the '''armgcc''' folder of each demo.
 
The DDR reserved area must match the one declared in the kernel device tree: at least 1 GB of RAM is required on the SoM to allow Cortex-M7 accessing the range 0x80000000 - 0x80FFFFFF.
 
The RPMSG area is located at 0x40000000: all SoMs allow Cortex-M7 accessing the RPMSG area.
 
After launching the build_all.sh command the following folder will be created in the armgcc folder
 
* '''ddr_debug''': containing DDR binaries compiled in debug mode (not stripped: symbols available)
* '''ddr_release''': containing DDR binaries compiled in release mode (stripped: no symbols available)
* '''debug''': containing TCM binaries compiled in debug mode (not stripped: symbols available)
* '''release''': containing TCM binaries compiled in release mode (stripped: no symbols available)

-->To allow Cortex M4 accessing shared resources without experiencing Linux kernel conflicts, a dedicated device tree must be loaded, containing '''m4''' label in the name, using the fdt_file environment variable in U-Boot.
This device tree disables some of the base device tree nodes in order to avoid conflicts between the main processor and Cortex M4.<br>

==Building Using Yocto==
<section begin=VAR-SOM-MX93_BUILDING_USING_YOCTO_SECTION/><!--
-->
In Yocto Dunfell and newer, Variscite provides a Yocto recipe for building and installing firmware into the Yocto image. Note, the examples below apply to the original release of this recipe in Dunfell and thus some of the syntax (such as the overrides) may need to be updated for newer versions.
https://github.com/varigit/meta-variscite-fslc/tree/dunfell/recipes-bsp/freertos-variscite
This recipe installs the following firmware files:
{{!}}-
{{!}} /boot/cm_<demo name>.bin.debug {{!}}{{!}} TCM {{!}}{{!}} U-Boot
{{!}}-
{{!}} /lib/firmware/cm_<demo name>.elf.debug {{!}}{{!}} TCM {{!}}{{!}} Linux Remoteproc Framework
If you have modified freertos-variscite in your own Git repository and kept the same directory structure, you can easily build your custom firmware by creating a bbappend file:
$ mkdir -p <your-layer>/recipes-bsp/freertos-variscite
$ nano <your-layer>/recipes-bsp/freertos-variscite/freertos-variscite_2.13.x.bbappend
Append '''SRC_URI''' and '''SRCREV''' to use your freertos-variscite Git repository
SRC_URI:remove = "git://github.com/varigit/freertos-variscite.git;protocol=git;branch=${MCUXPRESSO_BRANCH};"
SRC_URI:append = " <your Git repository>"
SRCREV = "<your Git commit id>"
Append '''CM_DEMOS''' to build your firmware. For example, to build rtos_examples/freertos_hello:
CM_DEMOS:append = "rtos_examples/freertos_hello"
Rebuild fsl-image-gui:
$ bitbake -c cleansstate freertos-variscite && bitbake fsl-image-gui
The firmware binary files should now be installed to /boot/ and elf files to /lib/firmware/
<section end=VAR-SOM-MX93_BUILDING_USING_YOCTO_SECTION/>
=== Running a demo ===
<section begin=VAR-SOM-MX93_RUNNING_DEMO_SECTION/><!--
-->
== Running a demo from U-Boot ==
To assist in loading M33 firmware from U-Boot prior to Linux boot, Variscite has created a dedicated set of U-Boot environment commands.
{{note|To allow Cortex-M accessing shared resources without experiencing Linux kernel conflicts, a dedicated device tree must be loaded.}}
To enable Cortex-M U-Boot auto-loading:
=> setenv use_m33 yes; saveenv
To disable Cortex-M U-Boot auto-loading:
=> setenv use_m33 no; saveenv
Note that the Cortex A55s and M33 have a different memory addressing "view" that is documented in the reference manual. Additionally, the bootaux command for the M33 uses secure aliases from the M33's point of view. Thus, two variables must be set properly in order to set the loading address (defaults used in the example below):
=> setenv m33_addr 0x201E0000
=> setenv m33_addr_auxview 0x1FFE0000
=> saveenv
To set the name of the Cortex-M binary
=> setenv m33_bin cm_hello_world.bin; saveenv
{{note|The .bin file is expected to exist in the directory /boot of the booting media.}}
<br>
After enabling as above, the U-Boot '''boot''' command will handle loading the Cortex-M firmware when the system begins the boot process. For testing, it is possible to invoke the Cortex-M33 boot process manually:
=> run loadm33bin && run runm33bin
After booting in Linux, the M33 will be listed as in the "attached" state by remoteproc:
# cat /sys/class/remoteproc/remoteproc0/state
attached
Additional details and step by step procedure to run each of the demos is available [{{#var:SDK_GIT_URL}}/blob/{{#var:SDK_GIT_BRANCH}}/{{#var:DOCS_FOLDER}}/{{urlencode:{{#var:NXP_USER_GUIDE}}|PATH}} online] or in the following document:
{{#var:SDK_PATH}}/freertos-variscite/{{#var:DOCS_FOLDER}}/{{#var:NXP_USER_GUIDE}}
{{note|This process can be simplified using /etc/remoteproc/variscite-rproc-u-boot in Linux<br>
Please refer to the Yocto Scripts section below for more information}}
== Running a demo from Linux ==
The Linux remoteproc framework can be used to load the Cortex-M33 firmware from Linux userspace.
{{note|The U-Boot M33 auto-loading must not be currently enabled in order to allow for remoteproc control and loading of the M33.}}
Increase kernel loglevel while debugging:
# sysctl kernel.printk=7;
If the state is 'running', stop the Cortex-M33
# echo stop > /sys/class/remoteproc/remoteproc0/state
Load new firmware
# echo cm_hello_world.elf > /sys/class/remoteproc/remoteproc0/firmware
{{note| The .elf file is expected to exist in the /lib/firmware directory}}
Run the new firmware
# echo start > /sys/class/remoteproc/remoteproc0/state
{{note|This process can be simplified using /etc/remoteproc/variscite-rproc-linux in Linux<br>
Please refer to the Yocto Scripts section below for more information}}
{{note|By default, Linux disables unused clocks. Certain M33 examples may use peripherals which are not enabled in Linux. Depending on the clock source, Linux may disable the clock by default, resulting in the example/peripheral not functioning. Therefore, when running M33 examples, it is recommended to override this. The easiest way to achieve this is to append the bootarg "clk_ignore_unused." }}
== Running a Demo using Yocto Scripts ==
In Yocto, Variscite provides scripts to simplify loading firmware via U-Boot or Linux:

DART-MX8M

Sections

Available dtbs

To allow Cortex M4 accessing shared resources without experiencing Linux kernel conflicts, a dedicated device tree must be loaded, by selecting the right version with the symbolic link in the /boot folder of the booting media.
These device trees contain m4 label in their name.


The below table lists an example dtb blob file name for DART-MX8M (on DT8MCustomBoard rev. 1.3 and higher) with support for M4 (and SD card and LVDS), for each kernel version / Yocto release:

File Name
 Description
imx8mq-var-dart-dt8mcustomboard-m4-sd-lvds.dtb For kernel >= 5.4.85 (Yocto >= Dunfell)
imx8mq-var-dart-m4-sd-lvds.dtb For kernel = 5.4.24 (Yocto Zeus)
fsl-imx8mq-var-dart-m4-sd-lvds.dtb For kernel = 4.19.35 (Yocto Warrior)
Image.gz-fsl-imx8mq-var-dart-m4-sd-lvds.dtb For kernel = 4.14.98 (Yocto Sumo)

For the full list of device tree blob files, refer to the "Build Results" section in the appropriate wiki page for the specific Yocto/Debian release you are using.

Default M4 pins

Default M4 pins used by the demos are:

Function Pin
debug UART (UART2) RX: J12.6 / TX: J12.4
GPIO (GPIO4_IO03) LED7 for DT8MCustomBoard 1.x

NXP Memory types

The SDK allow linking using 2 different memory types: DDR, TCM.

Here is available a short summary of memory areas used by Cortex-M4 as described in related linker file.

memory type M4 memory area A53 memory area memory lentgh linker file
DDR 0x80000000-0x801FFFFF (code)
0x80200000-0x803FFFFF (data)
0x80400000-0x80FFFFFF (data2) 		0x80000000-0x801FFFFF (code)
0x80200000-0x803FFFFF (data)
0x80400000-0x80FFFFFF (data2) 		16MB (DDR) MIMX8MQ6xxxJZ_cm4_ddr_ram.ld
TCM 0x1FFE0000-0x1FFFFFFF (code)
0x20000000-0x2001FFFF (data)
0x80000000-0x80FFFFFF (data2) 		0x007E0000-0x007FFFFF (code)
0x00800000-0x0081FFFF (data)
0x80000000-0x80FFFFFF (data2) 		256kB (TCM) + 16MB (DDR) MIMX8MQ6xxxJZ_cm4_ram.ld

All linker files are locate in the armgcc folder of each demo.

The DDR reserved area must match the one declared in the kernel device tree: at least 2 GB of RAM is required on the SoM to allow Cortex-M4 accessing the range 0x80000000 - 0x80FFFFFF.

The RPMSG area is located at 0xB8000000: at least 3 GB of RAM is required on the SoM to allow Cortex-M4 accessing the RPMSG area. After launching the build_all.sh command the following folder will be created in the armgcc folder

  • ddr_debug: containing DDR binaries compiled in debug mode (not stripped: symbols available)
  • ddr_release: containing DDR binaries compiled in release mode (stripped: no symbols available)
  • debug: containing TCM binaries compiled in debug mode (not stripped: symbols available)
  • release: containing TCM binaries compiled in release mode (stripped: no symbols available)

Further details about memory mapping are available in the following i.MX 8M Applications Processor Reference Manual paragraphs:

  • 2.1.2 Cortex-A53 Memory Map
  • 2.1.3 Cortex-M4 Memory Map

Variscite Memory types

The SDK allow linking using 2 different memory types: DDR, TCM.

Here is available a short summary of memory areas used by Cortex-M4 as described in related linker file.

All linker files are locate in the armgcc folder of each demo.

The DDR reserved area must match the one declared in the kernel device tree: at least 1 GB of RAM is required on the SoM to allow Cortex-M4 accessing the range 0x7E000000 - 0x7EFFFFFF. For some reason, Cortex-M4 is not able to access RAM locations below 0x60000000: SoMs with 512 MB of RAM are not suitable to use Cortex-M4.

The RPMSG area is located at 0x40000000: all SoMs allow Cortex-M4 accessing the RPMSG area.

After launching the build_all.sh command the following folder will be created in the armgcc folder

  • ddr_debug: containing DDR binaries compiled in debug mode (not stripped: symbols available)
  • ddr_release: containing DDR binaries compiled in release mode (stripped: no symbols available)
  • debug: containing TCM binaries compiled in debug mode (not stripped: symbols available)
  • release: containing TCM binaries compiled in release mode (stripped: no symbols available)

DART-MX8M-MINI

Sections

Available dtbs

To allow Cortex M4 accessing shared resources without experiencing Linux kernel conflicts, a dedicated device tree must be loaded, containing m4 label in the name, using the fdt_file environment variable in U-Boot.

This device tree disables some of the base device tree nodes in order to avoid conflicts between the main processor and Cortex M4.

Variscite Memory types

The SDK allow linking using 2 different memory types: DDR, TCM.

Here is available a short summary of memory areas used by Cortex-M4 as described in related linker file.

memory type M4 memory area A53 memory area memory lentgh linker file
DDR 0x7E000000-0x7E1FFFFF (code)
0x7E200000-0x7E3FFFFF (data)
0x7E400000-0x7EFFFFFF (data2) 		0x7E000000-0x7E1FFFFF (code)
0x7E200000-0x7E3FFFFF (data)
0x7E400000-0x7EFFFFFF (data2) 		16MB (DDR) MIMX8MM6xxxxx_cm4_ddr_ram.ld
TCM 0x1FFE0000-0x1FFFFFFF (code)
0x20000000-0x2001FFFF (data)
0x7E000000-0x7EFFFFFF (data2) 		0x007E0000-0x007FFFFF (code)
0x00800000-0x0081FFFF (data)
0x7E000000-0x7EFFFFFF (data2) 		256kB (TCM) + 16MB (DDR) MIMX8MM6xxxxx_cm4_ram.ld

All linker files are locate in the armgcc folder of each demo.

The DDR reserved area must match the one declared in the kernel device tree: at least 1 GB of RAM is required on the SoM to allow Cortex-M4 accessing the range 0x7E000000 - 0x7EFFFFFF. For some reason, Cortex-M4 is not able to access RAM locations below 0x60000000: SoMs with 512 MB of RAM are not suitable to use Cortex-M4.

The RPMSG area is located at 0x40000000: all SoMs allow Cortex-M4 accessing the RPMSG area.

After launching the build_all.sh command the following folder will be created in the armgcc folder

  • ddr_debug: containing DDR binaries compiled in debug mode (not stripped: symbols available)
  • ddr_release: containing DDR binaries compiled in release mode (stripped: no symbols available)
  • debug: containing TCM binaries compiled in debug mode (not stripped: symbols available)
  • release: containing TCM binaries compiled in release mode (stripped: no symbols available)

Further details about memory mapping are available in the following i.MX 8M Mini Applications Processor Reference Manual paragraphs:

  • 2.1.2 Cortex-A53 Memory Map
  • 2.1.3 Cortex-M4 Memory Map

VAR-SOM-MX8M-NANO

Sections

Available dtbs

To allow Cortex M7 accessing shared resources without experiencing Linux kernel conflicts, a dedicated device tree must be loaded, containing m7 label in the name, using the fdt_file environment variable in U-Boot.

Memory types

The SDK allow linking using 2 different memory types: DDR, TCM.

Here is available a short summary of memory areas used by Cortex-M7 as described in related linker file.

memory type M7 memory area A53 memory area memory lentgh linker file
DDR 0x7E000000-0x7E1FFFFF (code)
0x7E200000-0x7E3FFFFF (data)
0x7E400000-0x7EFFFFFF (data2) 		0x7E000000-0x7E1FFFFF (code)
0x7E200000-0x7E3FFFFF (data)
0x7E400000-0x7EFFFFFF (data2) 		16MB (DDR) MIMX8MN6xxxxx_cm7_ddr_ram.ld
TCM 0x00000000-0x0001FFFF (code)
0x20000000-0x2001FFFF (data)
0x7E000000-0x7EFFFFFF (data2) 		0x007E0000-0x007FFFFF (code)
0x00800000-0x0081FFFF (data)
0x7E000000-0x7EFFFFFF (data2) 		256kB (TCM) + 16MB (DDR) MIMX8MN6xxxxx_cm7_ram.ld

All linker files are locate in the armgcc folder of each demo.

The DDR reserved area must match the one declared in the kernel device tree: at least 1 GB of RAM is required on the SoM to allow Cortex-M7 accessing the range 0x7E000000 - 0x7EFFFFFF. For some reason, Cortex-M7 is not able to access RAM locations below 0x60000000: SoMs with 512 MB of RAM are not suitable to use Cortex-M7.

The RPMSG area is located at 0x40000000: all SoMs allow Cortex-M7 accessing the RPMSG area.

After launching the build_all.sh command the following folder will be created in the armgcc folder

  • ddr_debug: containing DDR binaries compiled in debug mode (not stripped: symbols available)
  • ddr_release: containing DDR binaries compiled in release mode (stripped: no symbols available)
  • debug: containing TCM binaries compiled in debug mode (not stripped: symbols available)
  • release: containing TCM binaries compiled in release mode (stripped: no symbols available)

Further details about memory mapping are available in the following i.MX 8M Nano Applications Processor Reference Manual paragraphs:

  • 2.1.2 Cortex-A53 Memory Map
  • 2.1.3 Cortex-M7 Memory Map

Variscite Memory types

The SDK allow linking using 2 different memory types: DDR, TCM.

Here is available a short summary of memory areas used by Cortex-M7 as described in related linker file.

memory type M7 memory area A53 memory area memory lentgh linker file
DDR 0x80000000-0x801FFFFF (code)
0x80200000-0x803FFFFF (data)
0x80400000-0x80FFFFFF (data2) 		0x80000000-0x801FFFFF (code)
0x80200000-0x803FFFFF (data)
0x80400000-0x80FFFFFF (data2) 		16MB (DDR) MIMX8MN6xxxxx_cm7_ddr_ram.ld
TCM 0x00000000-0x0001FFFF (code)
0x20000000-0x2001FFFF (data)
0x80000000-0x80FFFFFF (data2) 		0x007E0000-0x007FFFFF (code)
0x00800000-0x0081FFFF (data)
0x80000000-0x80FFFFFF (data2) 		256kB (TCM) + 16MB (DDR) MIMX8MN6xxxxx_cm7_ram.ld

All linker files are locate in the armgcc folder of each demo.

The DDR reserved area must match the one declared in the kernel device tree: at least 1 GB of RAM is required on the SoM to allow Cortex-M7 accessing the range 0x80000000 - 0x80FFFFFF.

The RPMSG area is located at 0x40000000: all SoMs allow Cortex-M7 accessing the RPMSG area.

After launching the build_all.sh command the following folder will be created in the armgcc folder

  • ddr_debug: containing DDR binaries compiled in debug mode (not stripped: symbols available)
  • ddr_release: containing DDR binaries compiled in release mode (stripped: no symbols available)
  • debug: containing TCM binaries compiled in debug mode (not stripped: symbols available)
  • release: containing TCM binaries compiled in release mode (stripped: no symbols available)

  • 2.3 Cortex-M7 Memory Map

VAR-SOM-MX8

Sections

Available dtbs

To allow Cortex M4 accessing shared resources without experiencing Linux kernel conflicts, a dedicated device tree must be loaded, containing m4 label in the name, using the fdt_file environment variable in U-Boot.

This device tree disables some of the base device tree nodes in order to avoid conflicts between the main processor and Cortex M4.

Additional demos may be provided on this platform in a future release.

The Wi-Fi/Bluetooth module interfaces have been disabled in the M33 device tree to not conflict with certain demos, however, if the module is present on your SoM, you should also disable the Wi-Fi service from running in Linux via "systemctl disable variscite-wifi"


Building Using Yocto

In Yocto Dunfell and newer, Variscite provides a Yocto recipe for building and installing firmware into the Yocto image. Note, the examples below apply to the original release of this recipe in Dunfell and thus some of the syntax (such as the overrides) may need to be updated for newer versions.

https://github.com/varigit/meta-variscite-fslc/tree/dunfell/recipes-bsp/freertos-variscite

This recipe installs the following firmware files: |- | /boot/cm_<demo name>.bin.debug || TCM || U-Boot |- | /lib/firmware/cm_<demo name>.elf.debug || TCM || Linux Remoteproc Framework

If you have modified freertos-variscite in your own Git repository and kept the same directory structure, you can easily build your custom firmware by creating a bbappend file: 

$ mkdir -p <your-layer>/recipes-bsp/freertos-variscite
$ nano <your-layer>/recipes-bsp/freertos-variscite/freertos-variscite_2.13.x.bbappend

Append SRC_URI and SRCREV to use your freertos-variscite Git repository 

SRC_URI:remove = "git://github.com/varigit/freertos-variscite.git;protocol=git;branch=${MCUXPRESSO_BRANCH};"
SRC_URI:append = " <your Git repository>"
SRCREV = "<your Git commit id>"

Append CM_DEMOS to build your firmware. For example, to build rtos_examples/freertos_hello: 

CM_DEMOS:append = "rtos_examples/freertos_hello"

Rebuild fsl-image-gui: 

$ bitbake -c cleansstate freertos-variscite && bitbake fsl-image-gui

The firmware binary files should now be installed to /boot/ and elf files to /lib/firmware/


Running a demo

Running a demo from U-Boot

To assist in loading M33 firmware from U-Boot prior to Linux boot, Variscite has created a dedicated set of U-Boot environment commands.


To allow Cortex-M accessing shared resources without experiencing Linux kernel conflicts, a dedicated device tree must be loaded.

To enable Cortex-M U-Boot auto-loading: 

=> setenv use_m33 yes; saveenv

To disable Cortex-M U-Boot auto-loading: 

=> setenv use_m33 no; saveenv

Note that the Cortex A55s and M33 have a different memory addressing "view" that is documented in the reference manual. Additionally, the bootaux command for the M33 uses secure aliases from the M33's point of view. Thus, two variables must be set properly in order to set the loading address (defaults used in the example below): 

=> setenv m33_addr 0x201E0000
=> setenv m33_addr_auxview 0x1FFE0000
=> saveenv

To set the name of the Cortex-M binary 

=> setenv m33_bin cm_hello_world.bin; saveenv


The .bin file is expected to exist in the directory /boot of the booting media.


After enabling as above, the U-Boot boot command will handle loading the Cortex-M firmware when the system begins the boot process. For testing, it is possible to invoke the Cortex-M33 boot process manually: 

=> run loadm33bin && run runm33bin

After booting in Linux, the M33 will be listed as in the "attached" state by remoteproc: 

# cat /sys/class/remoteproc/remoteproc0/state 
attached


Additional details and step by step procedure to run each of the demos is available online or in the following document: 

~/var-mcuxpresso/freertos-variscite/docs/Getting Started with MCUXpresso SDK for MEK-MIMX8QM.pdf


This process can be simplified using /etc/remoteproc/variscite-rproc-u-boot in Linux
Please refer to the Yocto Scripts section below for more information

Running a demo from Linux

The Linux remoteproc framework can be used to load the Cortex-M33 firmware from Linux userspace.


The U-Boot M33 auto-loading must not be currently enabled in order to allow for remoteproc control and loading of the M33.

Increase kernel loglevel while debugging: 

# sysctl kernel.printk=7;

If the state is 'running', stop the Cortex-M33 

# echo stop > /sys/class/remoteproc/remoteproc0/state

Load new firmware 

# echo cm_hello_world.elf > /sys/class/remoteproc/remoteproc0/firmware
The .elf file is expected to exist in the /lib/firmware directory

Run the new firmware 

# echo start > /sys/class/remoteproc/remoteproc0/state


This process can be simplified using /etc/remoteproc/variscite-rproc-linux in Linux
Please refer to the Yocto Scripts section below for more information


By default, Linux disables unused clocks. Certain M33 examples may use peripherals which are not enabled in Linux. Depending on the clock source, Linux may disable the clock by default, resulting in the example/peripheral not functioning. Therefore, when running M33 examples, it is recommended to override this. The easiest way to achieve this is to append the bootarg "clk_ignore_unused."

Running a Demo using Yocto Scripts

In Yocto, Variscite provides scripts to simplify loading firmware via U-Boot or Linux:

Script Description
/etc/remoteproc/variscite-rproc-u-boot Configure U-Boot to load firmware on boot
/etc/remoteproc/variscite-rproc-linux Load and run firmware using Linux remoteproc framework

Examples

variscite-rproc-u-boot example on imx93-var-som: 

root@imx93-var-som:~# /etc/remoteproc/variscite-rproc-u-boot -f /boot/cm_hello_world.bin.release 
Configuring for TCM memory
+ fw_setenv m33_addr 0x201E0000
Cannot read environment, using default
+ fw_setenv fdt_file imx93-var-som-symphony-m33.dtb
+ fw_setenv use_m33 yes
+ fw_setenv m33_bin cm_hello_world.bin.release
+ fw_setenv kernelargs ' clk_ignore_unused'
+ fw_setenv m33_addr_auxview 0x1FFE0000

Finished: Please reboot, the m33 firmware will run during U-Boot

variscite-rproc-linux example on imx93-var-som: 

root@imx93-var-som:~# /etc/remoteproc/variscite-rproc-linux -f /lib/firmware/cm_hello_world.elf.release
Cortex-M: Loading cm_hello_world.elf.release
Cortex-M: Starting
[  974.434796] remoteproc remoteproc0: powering up imx-rproc
[  974.442420] remoteproc remoteproc0: Booting fw image cm_hello_world.elf.release, size 99776
[  974.451172] remoteproc remoteproc0: header-less resource table


NXP Memory types

The SDK currently allows linking only out of TCM.

Below is a short summary of memory areas used by Cortex-M33 as described in related linker file:

Memory Type M33 Memory Area A55 Memory Area Memory Length Linker File
TCM 0x0FFE0000 - 0x0FFFFFFF (code)
0x20000000 – 0x2001FFFF (data) 		0x201E0000 – 0x201FFFFF (code)
0x20200000 – 0x2021FFFF (data) 		128kB (Code TCM) + 128kB (System TCM) MIMX9352_cm33_ram.ld

All linker files are located in the armgcc folder of each demo. Please consult the linker file for the actual memory used by each demo.

After launching the build_all.sh command the following folder will be created in the armgcc folder

  • debug: containing TCM binaries compiled in debug mode (not stripped: symbols available)
  • release: containing TCM binaries compiled in release mode (stripped: no symbols available)


JTAG

The JTAG interface is not exposed directly on the VAR-SOM-MX93 but the associated signals are exposed via the J1 SOM connector, which are shown in the table below:

Signal SoC balls VAR-SOM-MX93 Pins Symphony Pins Segger Adapter Pins
TCLK_SWCLK Y1 J1.51 J18.8 9
TDI W1 J1.53 J18.6 5
TDO_TRACESWO Y2 J1.52 J18.4 13
TMS_SWDIO W2 J1.50 J18.10 7
Vtref J3.2 1
GND J3.20 4


These signals are shared with the Wi-Fi module if present, so usage will require disabling this interface and making any appropriate pin muxing adjustments.

Please refer to SoM datasheet for further details.


The JTAG interface is not exposed directly on the VAR-SOM-MX93 / DART-MX93 but the associated signals are exposed via the J1 connector for the VAR-SOM-MX93 and via the J2 connector for the DART-MX93. They are shown in the table below:

Signal SoC balls VAR-SOM-MX93 Pins Symphony Pins DART-MX93 Pins DT8MCB Pins Segger Adapter Pins
TCLK_SWCLK Y1 J1.51 J18.8 J2.26 J12.7 9
TDI W1 J1.53 J18.6 J2.24 J12.5 5
TDO_TRACESWO Y2 J1.52 J18.4 J2.20 J12.1 13
TMS_SWDIO W2 J1.50 J18.10 J2.22 J12.3 7
Vtref J3.2 J13.3 1
GND J3.20 J13.4 4


For both the DART-MX93 and VAR-SOM-MX93 "WBD" or "WBE" SoMs, the JTAG pins are configured as UART5 signals used by the Wi-Fi/Bluetooth module. To use JTAG, it is necessary to disable this interface and make the necessary pin muxing adjustments. The Cortex-M33 dedicated device trees, as mentioned in the Prerequisites section, already disable the Wi-Fi/Bluetooth module, allowing for JTAG use as described above.

Please refer to SoM datasheet for further details.
