Hi everyone,
I am currently using FEL and Fastboot to flash a sunxi-device with SPL and u-boot.
In my board, I have two MMC devices: a MMC slot and an eMMC.
My use-case is to flash an empty device. I want to use FEL to boot a u-boot and then, use fastboot to flash u-boot into eMMC.
When I am using an u-boot via FEL, the eMMC is configured as MMC1. To be able to flash u-boot on it, I need to set CONFIG_FASTBOOT_FLASH_MMC_DEV to
- Thanks to that, the flashboot command is working fine.
But when I am booting on my fresh u-boot from eMMC, it is now configured as MMC0 and not MMC1 anymore.
It produces some problems in my case as I configured the CONFIG_FASTBOOT_FLASH_MMC_DEV to 1 so I can not use fastboot anymore to flash the eMMC (as, now, fastboot is trying to flash u-boot on my MMC slot and not my eMMC). This is clearly not what I wanted to. I would like to use fastboot to flash the same MMC device: eMMC.
This issue is located in this part of the code: http://git.denx.de/?p=u-boot.git;a=blob;f=board/sunxi/board.c;h=53656383d512...
Do you know why sunxi boards have this behavior ? Why this MMC device's swap is implemented ?
Thank you in advance for your help,
Best regards,
