Hi Bjorn, I was able to program the Thingy with good stability using nRFgoStudio, thank you! But, unable to see any serial output on Jlink RTT viewer. However, I'm happy to atleast be able to program my firmware to the Thingy now. Regards, Shubhangi

The Thingy:52 was not designed to be run directly over USB, so that could contribute to the instability. Were you able to fix all of your issues? Or do you still have any queries I can help you answer?

Hi, I changed my device (using another Thingy), and this one seems stabler. Also, I had used the USB port to provide power to the previous Thingy, whereas the current one is simply using the battery. Not sure if this caused the issue.

Hi Bjorn, Thank you very much for your response! I have used nrfgostudio, however I have stability issues with it (linked to the jLinkArm.dll file, again), as in the screenshot attached. Any suggestions to overcome this would be really appreciated!! Thanks again, Shubhangi

I was able to flash fw with nRF Go Studio, but it was unstable. I got the following error several times, not sure why.

If I were you, I would flash the Thingy FW via the nrfgostudio program instead. Take a look at this devzone case to get you started. Download the latest FW hex file here first. Plug in the SWD cable like you said & then follow this link. Hope that helps!
