Hi TI experts,
customer want to boot custom AM335x board from eMMC flash with 4bit mode.
Now, they flash eMMC with below way
1)boot custom board with on-board NAND flash
2)echo 0 > /sys/block/mmcblk0boot0/force_ro enable write access to the emmc boot0 partition
3)dd if=MLO of=/dev/mmcblk0boot0 seek=0
4)dd if=u-boot.img of=/dev/mmcblk0boot0 seek=768
5)Reboot board and pause U-boot
6)change u-boot environment variable
mmc bootbus 0 1 0 0
mmc partconf 0 1 1 1
7）set board to eMMC boot mode and power again.
Could you pls check whether the operation process correct, or is there a better way to write U-boot into the boot0 partition of eMMC？
The below shows that AM335x don't support boot from boot partition?
Linux/PROCESSOR-SDK-AM335X: Boot from eMMC boot partition
So it's means that need to create boot partition on UDA area and u-boot partition format as FAT32, set the boot flag?
Thanks so much for your reply
Best regards,
Jason
