Can't flash PCA10040

q

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

    So you don't want to program external chips with the board anymore? You want to use the on board chip together with nRF Connect? Firstly I would remove anything from the Debug Out port, if it then doesn't work I would suspect there has been done hardware changes to the board. Could that be?

    Exactly, I want to program the onboard nrf52. I've removed the debug cords, but it doesn't seem to make a difference.

    I've compared all of the solder traces between the two boards and they look identical. I don't see any other obvious hardware modifications. So you don't think it's likely to be a software issue?

    I'm not sure. Suspecting a hardware issue since you are able to flash external chips. Have you checked that the chip is powered? I guess you could also try to use Debug In, and see if you can program it with the working PCA10040 v1.1.1, when running with a battery or similar.
