Overview
MCU-PLUS-SDK 08.06.00.18 for for AM62X
This SDK contains examples, libraries and tools to develop RTOS and no-RTOS based applications for ARM M4F CPU, ARM R5F CPU and related peripherals.
The examples and demos supported from TI in this SDK are:
1. Empty Project 2. Hello World Project 3. Hello World C++ Project 4. OS Kernel and Driver Porting Layer (DPL) 5. SOC and Board Peripheral Drivers 6. Secondary Bootloader (SBL) 7. Reset Isolation - MCU Domain 8. Extended OTP Test 9. Software Diagnostics Library (SDL)
For more details please see https://software-dl.ti.com/mcu-plus-sdk/esd/AM62X/08.06.00.18/exports/docs/api_guide_am62x/EXAMPLES.html
The examples are arranged as below

Demos pins for M4F core
Default M4F pins used by the demos are:
| Function | SoC balls | VAR-SOM-AM62 pins | Symphony pins | Notes |
|---|---|---|---|---|
| UART2 RXD/TXD | R24/R25 | J1.115/J1.171 | J18.9 / J18.7 | The UART2 is not an instance from the MCU domain so only the polling mode is supported. To more details: Accessing main and wakeup domain peripherals from MCU domain Don't use /dev/ttyS2 from linux while running M4F examples to avoid conflicts. |
| MCU_GPIO0_14 (Input) | B3 | J1.155 | J13.16 (HDMI connector) | HDMI to header connector adapter is required |

You can build and run the demos following official TI documentation:
https://software-dl.ti.com/mcu-plus-sdk/esd/AM62X/08.06.00.18/exports/docs/api_guide_am62x/MAKEFILE_BUILD_PAGE.html https://software-dl.ti.com/mcu-plus-sdk/esd/AM62X/08.06.00.18/exports/docs/api_guide_am62x/GETTING_STARTED_BUILD.html
Building a demo
Building hello_world for MCU M4F
$ cd ~/mcu-plus-sdk-am62x
$ export PROJDIR=examples/hello_world/var-som-am62/m4fss0-0_freertos/ti-arm-clang/
$ make -s help
$ make -s -C ${PROJDIR} clean
$ make -s -C ${PROJDIR}
This produce the M4F binary ${PROJDIR}/am62-mcu-m4f0_0-fw for RTOS OS
To build for NO RTOS use:
$ export PROJDIR=examples/hello_world/var-som-am62/m4fss0-0_nortos/ti-arm-clang/
Building hello_world for WKUP R5F (DM R5)
$ cd ~/mcu-plus-sdk-am62x
$ export PROJDIR=examples/hello_world/var-som-am62/r5fss0-0_freertos/ti-arm-clang/
$ make -s help
$ make -s -C ${PROJDIR} clean
$ make -s -C ${PROJDIR}
This produce the R5F binary ${PROJDIR}/am62-wkup-r5f0_0-fw for RTOS OS
To build for NO RTOS use:
$ The hello_world NO RTOS is not available for R5F core
