Regarding Interfacing Jlink/JTrace to nrf based uBlox Modem for programming and debugging

[Samarth.Viswanath]

Hi,

    I am a Embedded System Engineer working in a Medical device company in Ireland. I have a ublox Modem(Nina-B111), which has a nRF5xxx module embedded into it. The modem needs to be re-programmed and debugged for new set of updates. The previous engineer did use a different mechanism , but did forget ot record/document it. Hence, I am in search of a J-Link/J-trace or any such similar debug/JTAG interfaces which support SWD(Serial Wire Debug) interface to ensure that the hex files generated can be pushed/programmed onto the nRF5xxx based ublox Chip. I have a Noerdic nRF52xxx development board, but I am in search of a specific programmed/debugger/JTAG interface so that the Firmware issues and the functionality can be accessed and debugged to ensure 100% working of the nRF based ublx chip. Can you kindly help me with providing the best avaialble solution along with some notes/demos which might give me the much required hint to solve the problem.

With Regards,

Samarth

Hello Samarth,

As Turbo J mentions, you can use the debugger on your development kit to both program and debug the nRF SoC on your module, as long as you have access to the SWD pins.
If you have not already, please see this blogpost on how to achieve this. You might also want to see this ticket for some brief answers to common questions often asked about this.

In the case that you are new to developing with the nRF series, this Product development page is a good place to start when familiarizing yourself with the available resources.

Please do not hesitate to let me know if you should encounter any other issues or questions!

Best regards,
Karl
