PN7642 Evalution board is not Connecting with Jlink and iJET Debuggers.

Hi Team,

Good Morning,

We are using the PN7642 evaluation board for our product development. We are using the Segger Jlink and Ijet debuggers to load and debug the code.

SDK Version:  2.12.5

FW Version: 2.02

when we load the example programs for the very first time it works fine and we can debug the board.

when we disconnected the debugger and tried to load the second time we were unable to connect the board with any debugger and it is showing jlink itself not able to detect.

we were unable to figure out the issue, why we were not able to connect the debuggers on the second time onwards. It happened with the two boards.

My doubt was when we connected the first time, it erased any registry settings that are related to debugging registers or any config registers, we needed to load it again.

Please support us on this issue, we are completely blocked on this issue.

Regards,

Srinivas. V

Hello @srinivasarao 

Unfortunately, I don't have J-link Debugger, so could not reproduce your issue. But I used LPC-LINK2 to debug on my side and there was no problem at all, so could you try to use LPC-LINK2 or MCU-LINK-PRO?

1) LPC-LINK2

2)  MCU-LINK-PRO
