Hello !


After week of usage I have got dead board effect : LPC55S69-evk "0 available SWD Devices detected" 

Mass erase with jumper J10 dosn't help. Board Revision A1.


What else is possible to try ?

I have also tru to replace debugger wit internal  Internal and External Debug Options for the NXP LPC55S69-EVK Board | MCU on Eclipse 


and external J-Link box and those are is also can't see any MCU core.

Now I revert to LPC-Link2/CMSIS-DAP again but something wrong with board.


Can it be repaired some how ?
