Hi Thooman,

are you using Windows 8 or Windows 10? If yes, then I think you have destroyed the bootloader/debug application on our board, see Bricking and Recovering OpenSDA Boards in Windows 8 and 10 | MCU on Eclipse . That article describes as well how to recover it. Another recovery method is described in How to Recover the OpenSDA V2.x Bootloader | MCU on Eclipse , but this only restores the image and requires an external probe. So whenever you go into bootloader mode again, Windows will destroy the board debug firmware.

I hope this helps,

Erich
