VisionSOM-RZ/x2L eMMC programming tool

usage

./rzx2l-loader.py -p <serial port> -l <loader>  --image <boot image>

where: - path to serial port, i.e. /dev/ttyUSB0 - path to loader file in motorola S-record format - path to emmc boot partition image file in binary format

example usage:

./rzx2l-loader.py -p /dev/ttyUSB0 -l Flash_Writer_SCIF_VSOM_G2L_1GB_DDR4_1GB_1PCS.mot  --image boot.img

dependencies

In order to run this tool, "pySerial" module is needed. It can be installed with command:

pip3 install --user pyserial

flash writer

For proper operation, it is necessary to use flash writer binary compiled from: https://github.com/SoMLabs/rzg2_flash_writer

Recommended build option for optimal performance:

CROSS_COMPILE=aarch64-none-linux-gnu- make -f makefile.linaro BOARD=VSOM_V2L_1GB SERIAL_FLASH=DISABLE MEM_CMD=DISABLE MEM_TEST_CMD=DISABLE EMMC_DISP=DISABLE

CROSS_COMPILE=aarch64-none-linux-gnu- make -f makefile.linaro BOARD=VSOM_G2L_1GB SERIAL_FLASH=DISABLE MEM_CMD=DISABLE MEM_TEST_CMD=DISABLE EMMC_DISP=DISABLE

eMMC boot partition format

Renesas RZ/X2L boot room expects following eMMC boot partition content:

-----------------------------
| sectors |     content     |
-----------------------------
|    0    |     unused      |
|   1..x  |     bl2_bp      |
| 256..x  |     fip.bin     |
-----------------------------

This can be generated i.e. with commands:

dd if=bl2_bp.bin of=boot.img seek=1 bs=512
dd if=fip.bin of=boot.img seek=256 bs=512
