Hey there everyone!
Recently one of the Electrons that I have seems to have gotten a corrupted boot loader ever since I let the LiPo battery run out several weeks ago. After coming back to it recently, the D7 LED is dimly lit and the center LED won’t turn on at all when I provide power to the board.
I first attempted to use the Norwegian Blue program on my second functional Electron to resolve this issue, but I kept receiving the “SWD Fault Error” message
I then attempted to use the STM32 ST-LINK Utility with a ST-LINK/V2 to program the boot loader, however ST-LINK Utility fails to connect to the target. The symptoms are much like the ones in this video:
After that, I attempted to update the firmware on the programmer and connect to the board through STM32CubeProgrammer with no luck. It was at this point that I noticed I am also unable to connect STM32 to functional Electrons as well. Any ideas as to what the issue may be? Thanks!
