Matek H743 Wing V2

Anyone had an issue or solution to flash this FC with Arduplane. I flash the firmware (Tried different versions of H743) onto the FC. Setup all settings and parameters as normal. As soon as the FC loses power or USB connection the firmware is gone on the FC. Can’t connect via mission planner and nothing is working. Any ideas would be appreciated.

Hi @iPeaches

Sounds like “hanging bootloader”
Have you tried this one:

PS: I have fixed the title of your message to Matek H743 Wing V2. There is no Matek F743.
