Setup

1. Clone Renesas BSP layer:

   $ git clone https://github.com/renesas-rz/rz-community-bsp.git -b scarthgap
   $ cd rz-community-bsp
   

2. Clone the Torizon layers into the rz-community-bsp folder

   $ git clone https://github.com/torizon/meta-torizon.git -b master
   $ git clone https://github.com/torizon/meta-torizon-bsp.git -b master
   

3. Clone Torizon dependencies into rz-community-bsp

   $ git clone https://github.com/uptane/meta-updater.git -b scarthgap
   $ git clone https://git.yoctoproject.org/meta-virtualization -b scarthgap
   

4. Create a symlink to our setup-environment:

   $ ln -s meta-torizon-bsp/scripts/setup-environment setup-environment
   

Build

1. Build with the following commands, inside rz-community-bsp

   $ ./kas-container shell --update --force-checkout kas/yocto/scarthgap.yml:kas/opt/debug.yml:kas/image/renesas-image-demo.yml:kas/machine/smarc-rzg2l.yml:kas/kernel/cip-6.1.yml
   $ cd /repo
   $ MACHINE=smarc-rzv2l . setup-environment
   $ bitbake torizon-docker
   

All artifacts should be inside build/deploy/images/smarc-rzv2l

Flash the Device

1. With SW11 set to OFF ON OFF ON, run (assuming ttyUSB0)

   cat Flash_Writer_SCIF_RZV2L_SMARC_PMIC_DDR4_2GB_1PCS.mot > /dev/ttyUSB0
   

2. Now following https://www.renesas.com/en/document/gde/smarc-evk-rzv2l-linux-start-gude-rev102?r=1569131, flash the bootloader

   > xls2
   ...
   ===== Please Input Program Top Address ============
   Please Input : H'11E00
   ===== Please Input Qspi Save Address ===
   Please Input : H'00000
   

   then

   $ cat bl2_bp-smarc-rzv2l.srec > /dev/ttyUSB0
   

   And again

   > xls2
   ...
   ===== Please Input Program Top Address ============
   Please Input : H'00000
   ===== Please Input Qspi Save Address ===
   Please Input : H'1D200
   

   then

   $ cat fip-smarc-rzv2l.srec > /dev/ttyUSB0
   

3. And finally copy the rootfs to the SD card Have the SD card in a single partition and run (assuming SD card is sdc)

   $ sudo dd if=torizon-docker-smarc-rzv2l-7.0.0-devel-20250127163415+build.0.ota-ext4 of=/dev/sdc1 oflag=direct bs=4M status=progress conv=fsync
   

Boot

With both steps above finished, just move sw11 to OFF OFF OFF ON, insert the SD card into CN10 and power on the device.
Press Enter on keyboard so you land on u-boot shell, and then run

=> env default -a
=> saveenv

This will reset the u-boot environment variables to their default values. After that just run

=> run bootcmd

It should boot straight into Common Torizon OS.

[!NOTE]
These steps in the bootloader should only be performed on the first boot of the device with Common Torizon OS. Subsequent boots or flashes should not require it.
