I was using a FRDM-KL25Z as a debugger for a custom board using MKL26Z64. Debugging and programming all went well using CodeWarrior 10.6 until, suddenly, when I tried to program the board, I got an error:
ARM GDI Protocol Adapter : Can't connect. BDM has no connection to target
The only thing I did before the error happened was to update USBDM to 126.96.36.199, but I managed to program the board once with the updated USBDM and drivers. After that, I just got the mentioned error.
I tried using a standalone USBDM programmer (USBDM-JS16-SWD-SER) with the custom board, but the error persists, meaning it must be something with the target processor.
I tested the setup with Windows XP SP3 (using CodeWarrior) and with Linux (using KDS 3.0.0).
