Yocto NAND Flash Burning

Introduction

The Variscite has either an on-SOM NAND flash or eMMC, and either of them can be used to boot from and to hold the file system.
For NAND flash we use a UBI file system and for eMMC we use ext4.

NAND flash structure

These are the defined MTD partitions on the NAND flash:
0x000000000000-0x000000200000 : "spl"
0x000000200000-0x000000400000 : "bootloader"
0x000000400000-0x000000c00000 : "kernel"
0x000000c00000-End                       : "rootfs"


eMMC structure

  • VAR-DART-MX6

0-4 MiB      : Non-partitioned space, saved for U-Boot.
4-12 MiB    : - A FAT16 partition containing the Linux image and the device tree blob/s.
12 MiB-End: "rootfs" - An ext4 partition containing the root file system (including the kernel modules).

Yocto Built binaries for NAND flash / eMMC

The resulted images are located at tmp/deploy/images/.

Flash from GUI

For this Yocto release, NXP/Vivante do no longer provide GPU accelerations for X11 native backend.

The default backend is now XWayland: Wayland accelerated backend with basic (not accelerated) X11 emulation.

Only "Flash from command line" is supported.


Setting the Boot Mode

Follow the instruction below according to the appropriate carrier board type:

MX6CustomBoard

Booting your MX6CustomBoard system from SD card requires pushing the middle button while powering up the system. See picture below.

Mx6 boot.jpg

To boot a board using an SD card, follow the steps below:

  • Power-off the board.
  • Insert the SD card into the SD/MMC slot of the carrier board (DVK)
  • Push the middle button (Boot Select) and hold
  • Power-up the board
  • Release the middle button (Boot Select) after system starts to boot.
  • The board will automatically boot into Linux from the SD card

SoloCustomBoard

Booting your system requires switching the relevant DIP switch to "Boot from MMC". See picture below.

Flash Recovery SD from GUI

Flash from GUI

DART-6UL Recovery Sumo.png

Touch/Click on the appropriate icon:

  • Install Yocto NAND, WiFi: Flash Yocto with WiFi support to NAND flash
  • Install Yocto NAND, SD card: Flash Yocto with SD card support to NAND flash
  • Install Yocto eMMC (SD/WiFi) : Flash Yocto to eMMC (installs both SD card and WiFi dtbs to the BOOT partition and let U-Boot select between them at boot time)


Setting the Boot Mode

Booting your system from an SD card requires switching the Boot DIP switches. See picture below.

Boot switch 6ul1.jpg
  • "00" The current position in the picture will set the system to boot from SD card
  • "01" Moving the right switch will set the system to boot from eMMC
  • "10" Moving the left switch will set the system to boot from NAND flash
  • "11" is illegal.
Be aware that your system has eMMC or NAND but never both.

  • ON-EXT: Boot from the external storage (SD card) - the current position in the picture
  • OFF-INT: Boot from the SOM's internal storage (eMMC/NAND flash)


Using only one Ethernet port

Apply the following patch to the Linux kernel source, for removing the second Ethernet port, in case your own custom carrier board only has one and doesn't have the second Ethernet phy:

Notes:
- You can follow the "Build Linux from source code" guide to get the Linux kernel source, apply the above patch, build only the device trees and copy them to your SD card.
- In older kernel releases where there is no imx6ul-imx6ull-var-dart-common.dtsi file, the relevant file to edit is called imx6ul-var-dart.dtsi


To remove the second Ethernet port, in case your own custom carrier board only has one and doesn't have the second Ethernet phy:
Edit the dtsi file of the reference carrier board in the Linux kernel source and remove the &fec1 and &fec2 nodes from it.
In case of the VAR-6ULCustomBoard (DART-6UL carrier), the file is arch/arm/boot/dts/imx6ul-imx6ull-var-dart-6ulcustomboard.dtsi.
In case of the Concerto-Board (VAR-SOM-6UL carrier), the file is arch/arm/boot/dts/imx6ul-imx6ull-var-som-concerto-board.dtsi.
The above will result in using the &fec1 node from the dtsi file of the SOM, as is (as the phy of the first Ethernet port is on the SOM), without adding the second port (which its phy is on the reference carrier board).

- You can follow the "Build Linux from source code" guide to get the Linux kernel source, apply the above patch, build only the device trees and copy them to your SD card.

Configuring RS485 Half-Duplex

Each UART can be configured for RS485 Half-Duplex mode by using a GPIO pin to drive the receive and transmit enable inputs. This can be configured in the device tree by making the following changes to the uart node and replacing X, Y & Z with the proper values: 

&uartX {                                                          /* Add RS485 properties to uartX */
	pinctrl-names = "default";
	pinctrl-0 = <&pinctrl_uartX>, <&pinctrl_uartX_rs485>;     /* Add RS485 GPIO pinctrl */
	rts-gpios = <&gpioY Z GPIO_ACTIVE_LOW>;                   /* Add rts-gpios property */
	linux,rs485-enabled-at-boot-time;                         /* Enable RS485 at boot time to skip using TIOCSRS485 ioctl */
	status = "okay";
};

Next, configure the RS485 GPIO pin by adding pinctrl_uartX_rs485 to iomuxc. Replace X, GPIO_PIN_FUNCTION, and GPIO_PIN_SETTINGS with the proper values: 

&iomuxc {
	pinctrl_uartX_rs485: uartXrs485 {
		fsl,pins = <
			GPIO_PIN_FUNCTION  GPIO_PIN_SETTINGS
		>;
	};
};

Note: For more information about configuring pins, please see i.MX Device Tree Pinmux Settings Guide


After making these changes, RS485 mode will be enabled by default and can be verified from the console by running the commands below. Replace N with the proper value, which is typically X-1 relative to the device tree node uartX: 

# stty -F /dev/ttymxcN -echo -onlcr 115200
# echo hello > /dev/ttymxcN

The below logic analyzer capture shows the RS485 RX/TX enable line toggling when writing to the UART:

Rs485.png


Please refer to the Linux device tree bindings for more RS485 configuration options. 


 Expression error: Unexpected > operator. Expression error: Unexpected >= operator. Expression error: Unexpected >= operator.  
$ cd 
$ MACHINE= DISTRO=


The above command is only mandatory for the very first build setup: whenever restarting a newer build session (from a different terminal or in a different time), you can skip the full setup and just run 

$ cd 
$ source setup-environment

Installing the Yocto binaries

If you followed the Create an extended SD card steps, the Yocto binaries and the flashing scripts will be included in your SD card.
The flashing scripts are easy-to-use example scripts for flashing images into NAND flash / eMMC.
There is also a section below describing how to flash the images manually.

Images locations

Following is the directory structure on your SD card, which elaborates the files' location that the below installation scripts are expecting:


Prepare the images for NAND flash / eMMC flashing

Plug the bootable SD card into your host machine and mount the rootfs partition - here we assume it is mounted on /media/rootfs.
Copy all the mentioned yocto-built binaries to the SD card: 


$ export YOCTO_IMGS_PATH=~/var-fsl-yocto/build_x11/tmp/deploy/images/imx95-var-dart
$ export P2_MOUNT_DIR=/media/rootfs/

Linux:
$ sudo cp ${YOCTO_IMGS_PATH}/Image.gz							${P2_MOUNT_DIR}/opt/images/Yocto/

NAND images: 

Device Tree:
$ sudo cp ${YOCTO_IMGS_PATH}/Image.gz-imx*nand*.dtb					${P2_MOUNT_DIR}/opt/images/Yocto/
$ sudo rename 's/Image.gz-imx/imx/'							${P2_MOUNT_DIR}/opt/images/Yocto/*.dtb

SPL/U-Boot:
$ sudo cp ${YOCTO_IMGS_PATH}/SPL-nand							${P2_MOUNT_DIR}/opt/images/Yocto/SPL
$ sudo cp ${YOCTO_IMGS_PATH}/u-boot.img-nand						${P2_MOUNT_DIR}/opt/images/Yocto/u-boot.img
 
File System:
$ sudo cp ${YOCTO_IMGS_PATH}/fsl-image-gui-imx95-var-dart.ubi					${P2_MOUNT_DIR}/opt/images/Yocto/rootfs.ubi.img

eMMC images: 

Device Tree:
$ sudo cp ${YOCTO_IMGS_PATH}/Image.gz-imx*emmc*.dtb					${P2_MOUNT_DIR}/opt/images/Yocto/
$ sudo rename 's/Image.gz-imx/imx/'							${P2_MOUNT_DIR}/opt/images/Yocto/*.dtb

SPL/U-Boot:
$ sudo cp ${YOCTO_IMGS_PATH}/N/A							${P2_MOUNT_DIR}/opt/images/Yocto/SPL
$ sudo cp ${YOCTO_IMGS_PATH}/imx-boot-sd.bin						${P2_MOUNT_DIR}/opt/images/Yocto/u-boot.img

File System:
$ sudo cp ${YOCTO_IMGS_PATH}/fsl-image-gui-imx95-var-dart.tar.bz2				${P2_MOUNT_DIR}/opt/images/Yocto/rootfs.tar.bz2

Flashing scripts

The flashing scripts are located on the SD card at /usr/bin/: 

install_yocto.sh	- Flash Yocto into NAND flash or eMMC (Run and follow usage instructions)

Manual step-by-step flashing to NAND flash

Use the prepared SD card to boot the board and run the following: 

$ cd /opt/images/Yocto

Flash SPL & U-Boot: 

$ flash_erase /dev/mtd0 0 0

Flash the Linux Kernel image & Device Tree:
You need to use the right .dtb file for you hardware setup. See the table above for a complete description. 

$ flash_erase /dev/mtd3 0 0
$ nandwrite -p /dev/mtd3 Image.gz
$ nandwrite -p /dev/mtd3 -s 0x7e0000 <DEVICE_TREE_FILE>

Flash the (UBI) File System to NAND flash: 

$ ubiformat /dev/ -f rootfs.ubi

Manual step-by-step flashing to eMMC

Flashing the eMMC requires several steps including partitioning, file system formatting and image extraction.
We recommend to use our provided scripts to perform this task.

Use the prepared SD card to boot the board and run the following: 

$ cd /opt/images/Yocto

Make sure the eMMC is not mounted: 

$ umount /dev/mmcblk0p*

Delete current data on eMMC: 

$ dd if=/dev/zero of=/dev/mmcblk0p1 bs=1024 count=1024
$ dd if=/dev/zero of=/dev/mmcblk0p2 bs=1024 count=1024
$ dd if=/dev/zero of=/dev/mmcblk0p3 bs=1024 count=1024
$ dd if=/dev/zero of=/dev/mmcblk0p4 bs=1024 count=1024
$ dd if=/dev/zero of=/dev/mmcblk0p5 bs=1024 count=1024
$ dd if=/dev/zero of=/dev/mmcblk0p6 bs=1024 count=1024
$ dd if=/dev/zero of=/dev/mmcblk0p7 bs=1024 count=1024
$ sync
$ (echo d; echo 1; echo d; echo 2; echo d; echo 3; echo d; echo w) | fdisk /dev/mmcblk0
$ sync
$ dd if=/dev/zero of=/dev/mmcblk0 bs=1M count=4
$ sync

Create a partition table: 

$(echo n; echo p; echo 1; echo 8192; echo 24575; echo t; echo c; \
  echo n; echo p; echo 2; echo 24576; echo; \
  echo p; echo w) | fdisk -u /dev/mmcblk0
$ sync

Format the partitions: 

$ mkfs.vfat /dev/mmcblk0p1 -n BOOT-VARMX7
$ mkfs.ext4 /dev/mmcblk0p2 -L rootfs

  Copy the Linux kernel image and the device tree blobs to the BOOT partition:

$ mkdir /run/media/mmcblk0p1
$ mount -t vfat /dev/mmcblk0p1	/run/media/mmcblk0p1
$ cp *emmc*.dtb			/run/media/mmcblk0p1
$ sync
$ umount /run/media/mmcblk0p1

Extract the rootfs archive: 

$ mkdir /run/media/mmcblk0p1
$ mount /dev/mmcblk0p1 /run/media/mmcblk0p1
$ tar xvpf rootfs.tar.bz2 -C /run/media/mmcblk0p1
$ sync
$ umount /run/media/mmcblk0p1


Summary

We described the results of a Yocto build, how to copy it to a bootable SD card and how to flash it to NAND and eMMC.
With our extended SD card and our recovery SD card we provide an installation script located at /usr/bin/install_yocto.sh. It is much safer to use it instead of flashing the system manually.
