custom nRF52 J-Link for UART

[RO]

I am working on a nRF52328 present in the Taiyo Yuden EYSHJNZXZ module. I am using a J-link EDU debugger to program it. Can I use the J-Link for UART communication with the PC?

Thanks.

Unless I am wrong, I don't think the J-Link EDU has the UART bridge. The IDAP-Link does have UART bridge.

none of the standalone JLinks have a UART bridge, there's nowhere on the debug interface pins for such a thing, only the JLink OnBoards have them as they can be customized for each chip.

You can use segger RTT or SWO, but that's it

[RO]

ok thanks.

[RO]

so can I use an additional FTDI chip for UART communication?

[RK]

yes. If you're just using it whilst debugging any of the USB/UART cheap adapters work, just hook up the lines.
