Dear all,
I'm using LPC-Link2 debugger for my Own PCB with LPC4357.
Some times debuggers pins are getting damaged. It is working only after controller is replaced with new one.
I haven't faced the similar problem with remaining series of MCUs(LPC1778/69 etc.,).

I thought it was due to high current sink/source into/from JTAG the pins.

Is it possible to rectify the issue using series resistors?

Thank you in advance.
