Hi
I have a PCA10040 V1.1.0 that my company has been using to flash test code onto other nRF52832 chips (I don't know the details, but it has wires attached to the debug out). I'm trying to use this board with nRF Connect, but I can't update the firmware. After plugging the board into the computer, I get this message: Detected firmware version 104.191.12. Do you want to update to version 1.1.0? After clicking ok, I get this error message: Error occurred opening serial port. (NRF_ERROR_TIMEOUT). In addition, I tried flash erasing the board with nrfjprog but I get this error:
JLinkARM DLL reported an error. Try again. If error condition
ERROR: persists, run the same command again with argument --log, contact Nordic
ERROR: Semiconductor and provide the generated log.log file to them.
Here is the log.log file:

I'm wondering if there is some protected flash memory on the device? I've tried asking other employees who set it up initially, but no one seems to know...
Also I have a PCA10040 V1.1.1 that works fine in both of the above circumstances, so I'm pretty sure these problems are not with the computer/software setup.
Many thanks
