Hi dmisol,

So your board is VIM2 but flash VIM firmware?

6390de64cfb905d13810344688da774f4c278211_1_690x344

Please try MRegister Mode.And then Upgrade Via an USB Cable to flash VIM2 firmware.

Thanks.

Hi numbqq,

yes (

There must be a way how mmc is initially flashed. Formerly it had been jtag at CPU. No idea how it works now, I’m a bit outdated…

Thanks!
