LPC Link 2 fails to program PN7462 by reporting error can not halt processor.

 

The only way to recover the chip is to activate USB bootloader. In our design we are not using USB and I need support to fix this issue. 

 

How come NXP designing MCU that can not be programmed by debugger/SWD?

I never had such a bad experience in past with any other vendor. 

 

 

Following is the log from LPC Link.
