Hi,
I used nRF91DK for almost 2 months non stop to debug the final nRF91 based board for our air quality monitoring hardware to fight the propagation of Covid virus.
But since the 1st January, when I connected to DK, without any host board connected vis Debug Out pins, I got this in nRF Programmer (serial number of DK, and name with REV1 at the end):
When I connect a host board to DK (SW11=3V, SW5=nRF91), I usually see the host board to select. But now I only see the same serial number of 9160DK, ending with "REV2":
And the RTT Viewer is showing this (no LED lit ON on the host board as it is supposed to be)
Here is how the host is connected to DK:
My colleague in charge of embedded software told me it might be an overheating issue for nRF9160DK (#33)
The related ticket suggests to press RESET button to see "Bootloader"but my DK always shows JLINK, so I am lost on how to make it come back to work
Let me know what you think about this. We are in hurry to fight covid with our technology which is in high demand.
Thanks again,
Saketaram
