Can not Flash STM32MP157FAD. with CubeProgrammer, and StarterPackage Image. First 2 files download ok, then get "Reconnecting the device...", and it never reconnects. And the MPU reset, with CubeProgrammer can download first 1 file. Windows11 drops the USB-DFU device. How to fix?

HI @xingya 

Could you please confirm you are using STM32MP157F-EV1 board or a custom board?
If you are using STM32MP157F-EV1 board, do the flashload works with provided Starter package ?

Reset reason shows IWDG2 watchdog reset, maybe something to look at.

Btw, your are using an old Ecosystem v2, which is not supported anymore. If you are still in development phase, we strongly encourage to switch to latest Ecosystem v5.

Regards.
