CMSIS-DAP and JLINK debuggers no longer working on IMXRT1050EVKB board

Hi,

After a few days of debugging on my iMX1050EVKB board, CMSIS-DAP no longer recognizes that there is any processor there, nor does a JLINK debugger. I've also tried IAR tools and they don't recognize it either. Is there any test I can run to see if the processor is fried or something else is wrong with the board or debugger?

Here is output from IAR:
