After changed from nRF52832 to nRF52810 on the same board, not working.

Hello.

Recently, our supplier recommend us to use nRF52810 instead of nRF52832.

These two MCU have same pin map, so just we pulled off existing nRF52832 from the board,

and put nRF52810 on the same place again.

but after this work, the board can't detect J-link. (before this work, it worked fine)

I totally changed 6 boards from nRF52832 to nRF52810. but no working board.

I checked the power and soldering condition, but there is nothing seems to be wrong.

Is there any solution for this?

Could you send any photo about PCB or pcb drawing folder? If i cheked your hardware i might help you.

I'm sorry for not sharing original PCB file because there are other PCB combined.

debugger pin is on the bottom of this PCB (please see yellow lines)

This is two sided board and really simple.

could you figure out what is the problem with this?

Hello Mr. Kim.

I would recommend you to create private ticket to share the PCB layout and schematic.

You can get technical supporting from Nordic tech support team directly if you have private ticket.

Hi Kim,

Sorry for the late response. Nordic staff have had Christmas holidays last week.

Could you measure the voltage level at DEC1, DEC2, DEC3 and DEC4?

And the voltage at VDD?

If you connect a signal analyzer to SWDIO and SWDCLK do you see any output there?

PS. if you don't want to share the layout and schematics of your design with others I can make this case private.

Best Regards,

Marjeris
