FRDM-K22F: Debugging/flashing issue

bulislaw — Fri, 06 May 2016 18:10:15 GMT

My FRDM-K22F board suddenly stopped working properly. I can't flash any programs on it, but everything else seem to work fine. When I connect it to my computer it's detected and mounted. Flashing bootloader also works. I've tried mbed and sagger bootloaders, flashing from Mac and Linux using KDS and also tried to just to copy one of the demo .bin files. While trying to debug using Sagger I'm getting:

I've tried using CodeWarrior on Linux, but it seems very dodgy and there was some generic error don't think it was in any way related.
