I was trying to program the MKM34Z256VLL7 MCU using a IAR for ARM 7.5 & PE micro debugger with a simple blinking & polling based switch code, when it reset(see pic 1). After closing the debug session & trying to reprogram the controller, I received the error "The flash loader reported an error" (see pic 2) followed by (see pic 3). Very new to this platform, any help would be greatly appreciated. We had programmed this board multiple times earlier without any issues.
Edit: tried to recover using Kinetis Recovery Tool, had no effect.
