Summary

Flashed fixed_dump that I foung here through stlink, was hoping that it boots but no luck. Tried to FF Firmware Writer after got following messages: Start control CMD M601 Received. Control Success. ok CMD M601 Received. Control Success. ok Create file failed Stop

When select trigger only receive:

CMD M601 Received. Control Success. ok CMD M601 Received. Control Success. ok succeed ok succeed ok Stop

run out of ideas, would be glad if someone has full dump or can make one.

Thanks.

Basic Example

Full dump.
