Why Flashing the FSBL Failed?

[SCho.3]

I have a DK2 board.

Downloading FSBL image for EV1 board to DK2 board through USB port on DFU by the STM32CubeProgrammer fails. Both boards use the STM32MP157C chip, but I don't understand why the download fails.

Can anyone explain the reason or principle?

Hi @SCho.3​ 

Are you using complete TSV file from EV1 ?

You need a custom one specifying DK2 fsbl1-boot and ssbl-boot for partition 0x1 and 0x3 ( they will be executed on DK2 for flash procedure)

Other partition kept with EV1 image partitions

Hope it help
