nRF Programmer - Unsupported device - custom nRF9160

okwestern

My custom nRF9160 board does not communicate with nRF Connect Programmer.

"Unsupported device. The detected device could not be recognized as neither JLink device nor Nordic USB device."

I also tried the modem firmware python script from Nordic, and it does not find any programmers with api.get_connected_probes().

I use a J-Link EDU Mini over SWD, latest firmware. When I use nrfjprog or J-Flash Lite, it erases, programs and verifies without problems - so I would assume connections, levels, etc. are correct.

I'm on Windows 7 and device manager shows only one instance, under Universal Serial Bus controllers->J-Link driver. It uses JLinkx64.sys driver 2.70h. I don't have any under Portable devices or Ports (COM).

I've searched the forums and tried some of the proposed solutions without luck.

Any suggestions?

    Hi,

     

    I use a J-Link EDU Mini over SWD, latest firmware. When I use nrfjprog or J-Flash Lite, it erases, programs and verifies without problems - so I would assume connections, levels, etc. are correct.

    My apologies. Since all other tools are able to detect the debugger successfully, it all points to the "programmer" app having a bug.

    I have reported this back to the developers, to that they are aware of this restriction/bug.

     

    Kind regards,

    Håkon

    If there is a bug, it also goes for the python package pynrfjprog, since the python script doesn't work either. Do they share the buggy code? 
    Are there previous versions available that work with EDU Mini I can use?

    nrfjprog works, but pynrfjprog does not?

    Could you post the error messages?

     

    Kind regards,

    There are no errors. api.get_connected_probes() just does not find any debuggers, therefore never enters the flashing.

    But "nrfjprog -i" reports the serial number of my debugger.

    import os
import time
import argparse
import subprocess
import logging
from tempfile import TemporaryDirectory, mkstemp
from pynrfjprog import HighLevel

logging.basicConfig(level=logging.INFO)
log = logging.getLogger('modem_update')


def flash_modem_pkg(modem_zip, verify):
    start = time.time()
    with HighLevel.API(True) as api:
        snr = api.get_connected_probes()
        for s in snr:
            log.info("Establish board connection")
            log.info(f"Flashing '{modem_zip}' to board {s}")
            with HighLevel.IPCDFUProbe(api, s, HighLevel.CoProcessor.CP_MODEM) as probe:
                log.info(f"Programming '{modem_zip}'")
                probe.program(modem_zip)
                log.info("Programming complete")
                if verify:
                    log.info("Verifying")
                    probe.verify(modem_zip)
                    log.info("Verifying complete")
        api.close()
        log.info(f"Completed in {time.time() - start} seconds")

def main():
    parser = argparse.ArgumentParser()
    parser.add_argument("modem_pkg")
    args = parser.parse_args()
    log.info("Modem firmware upgrade")
    flash_modem_pkg(args.modem_pkg,True)

if __name__ == '__main__':
    main()
