You can just change as you want. We have this file in buildroot, uuu can run command on the device using FB command. Example how call it
Thanks for sharing the example.
I adapted the UUU script like this:
SDPS: boot -f flash.bin FB: ucmd setenv fastboot_buffer ${loadaddr} FB: ucmd mmc dev 2 1 FB: download -f flash.bin FB: ucmd setexpr blkcnt $filesize + 0x1ff FB: ucmd setexpr blkcnt $blkcnt / 0x200 FB: ucmd mmc write $loadaddr 0 $blkcnt FB: reboot FB: done
Did the following changes based on imx8mn_bsh_smm_s2pro:

and now UUU correctly flashes the eMMC hardware partition.
Thanks a lot,
