Hi Kazi,

using nrfjprog programming my xm122 works. Thank you for your support.

Greetings

Hello Thomas,

The most common cause of programming and verification errors is a mismatch in voltage levels between the DK (debugger/programmer) and the target board. You can read this case https://devzone.nordicsemi.com/f/nordic-q-a/114638/flash-error-sometime. Both must have share a common ground and have compatible VDD levels. As you said. both DK and XM122 are powered from the common surce ( your notebook), I can say they have same voltage level.

All the SWD/JTAG connections are correct and solid? You can check with this case (+) How to program an external board using a DK board? - Nordic Q&A - Nordic DevZone - Nordic DevZone which shows and explains the connection between programmer and target board.

Besides this, If the target device has access protection (e.g., readback protection or application protection) enabled, programming and verification will fail. In this situation, you have to do recover by nrfjprog --recover command.

You also can check jlink firmware version if it is updated.

You may try to run the program from nRF Command Line Tools (nrfjprog) to run the program instead of Jflash to see if the issue still persists?

Hi Kazi,

I tested several combinations to check that cause. My nrf52dk is always conneted to my Notebook. The xm122 was power by two different USB chargers, my dockingstation. At last both devices were directly connected to USB ports of my notebook.

These tests had no effect to my issue.

Hello,

One of the common reasons for not programming the module ( here XM122) by nR52840 DK may be related to the power supply. If Supply voltage of xm122 is not same as DK, it occurs. How have you powered the DK and XM122?
