Hi,

Are you using a NXP board??

Do you try using a LPCOpen example?

Please check the below threads and let me know if this helps!!

ISP Reset over debug 

Regaining debug access to target MCU 

Have a great day,
Soledad

Thanks for your feedback, it did help to solve the problem.

This was on a customer design based on the LPC1549 NXP board.

It had a level shifter  on one of the ISP pins, the level shifter was configured wrong.
