Does anyone have a working fw_env.conf file for the BPI-R3 (or know what’s going on)? My existing file currently has:
# MTD device name Device offset Env. size Flash sector size Number of sectors
/dev/mmcblk0p2 0x300000 0x80000
and I am using it with uboot 2024.01 and uboot-tools 2024.01. It works well enough for fw_printenv however if I try to modify the environment I get a write error:
$ fw_setenv test123 asd
Seek error on /dev/mmcblk0p2: Invalid argument
Error: can't write fw_env to flash
Haven’t tried fw_{set,print}env from U-Boot 2014.01 yet, but I can tell you that what is included with U-Boot 2023.07.02 does work fine.
And just to be sure regarding fw_printenv seemingly working fine: Can you double check please that what it displays is really the content of your env and not a default it spits out in case it cannot access it?
Thanks Daniel. Yes, the fw_printenv does work as expected i.e. prints the correct data. I only recently moved to the 2024.01, but was having the same issue on the 2023.10. I am using @frank-w git branch (GitHub - frank-w/u-boot: U-Boot-Bootloader for BananaPI-R2/R64/R2Pro/R3). Are you using some other repo? If yes, maybe you can share that such that I can look for relevant patches.
