Modem DFU fails on nRF9160 using nRF Connect

Hi,

There seems to be some compatibility issues with modem DFU and Ubuntu 16, it does however work with Ubuntu 18. We are looking into the issue, and I will post an update here when a fix is ready.

Good news. I got it to work, finally. Using pynrfjprog 10.2.1, JLink version 6.46c and nrfjprog v 9.8.1

no more wonky JLINK_DLL errors

Hi,

I only have one version of nrfjprog installed, located in /usr/bin after installing though the .deb package.

I ran Windows 10 in Virtualbox on the same machine and passed the USB device through, and I was able to update the modem firmware with no issues from Windows 10.

FWIW, I have this issue, too. Using Python 3.6 on Ubuntu 18.04 -- managed to get it to work in a VM -- and AFAIK all installed versions are correct. Cannot get it to work, again, on any different machines.

Do you have multiple versions of nrfjprog installed? Could you check that $PATH only points to one installation?

Just to be 100% sure that this is a ubuntu environment issue, and not an issue with the board itself, could you try to use e.g a windows computer and try to use that to update the modem fw on the board?

I am unable to run the latest nRF Connect AppImage as root. It returns immediately with exit code 0 without launching anything. I can run version <= 3.0.0 as root, but the Programmer application does not launch from these versions of nRF Connect.

Your python script fails with the same error (even when running it as sudo):

Traceback (most recent call last):
  File "dfu.py", line 6, in <module>
    probe = HighLevel.IPCDFUProbe(api, s, HighLevel.CoProcessor.CP_MODEM)
  File "/home/fredrik/.local/lib/python3.7/site-packages/pynrfjprog/HighLevel.py", line 558, in __init__
    raise APIError(result, log=self._logger.error)
pynrfjprog.APIError.APIError: An error was reported by NRFJPROG DLL: -151 NRFJPROG_SUB_DLL_COULD_NOT_BE_OPENED.

I tried downgrading pynrfjprog to version 10.3.0 (the same as my current nrfjprog installation) and running the script again. This time it fails here:

Traceback (most recent call last):
  File "dfu.py", line 13, in <module>
    probe.program("mfw-nrf_9160-1.0.1.zip")
  File "/home/fredrik/miniconda3/lib/python3.7/site-packages/pynrfjprog/HighLevel.py", line 307, in program
    raise APIError(result, log=self._logger.error)
pynrfjprog.APIError.APIError: An error was reported by NRFJPROG DLL: -3 INVALID_PARAMETER.

I can see the LED blinking on the nRF91 DK just before it crashes though, so there is at least some communication.

For the record, I am using Python 3.7.3.

Hi,

Does it work if you run nRF-Connect for Desktop as sudo ?

[quote user="fellerts"]Are there any CLI tools I can use instead? [/quote]

You could try to do the modem DFU using this python script

from pynrfjprog import HighLevelapi = HighLevel.API()
api.open()
snr = api.get_connected_probes()
for s in snr:
    probe = HighLevel.IPCDFUProbe(api, s, HighLevel.CoProcessor.CP_MODEM)
    probe.program("mfw-nrf_9160-1.0.0.zip")
    probe.verify("mfw-nrf_9160-1.0.0.zip")
 
api.close()

Hi Sigurd,

There seems to be an issue with nrfjprog v10.4.0 on Linux64. After unpacking the tar archive, I run

$ sudo dpkg -i nRF-Command-Line-Tools_10_4_0_Linux-amd64.deb

And then to check that the installation worked, I run

$ cd ~
$ nrfjprog --version
ERROR: nrfjprog.ini not found. Please reinstall nrfjprog.

I'm not sure what's wrong here, as nrfjprog.ini is present in /opt/nrfjprog:

$ ls /opt/nrfjprog/
DllCommonDefinitions.h          libhighlevelnrfjprog.so             libnrfjprogdll.so  nrfjprog.ini
highlevelnrfjprogdll.h          libjlinkarm_nrf51_nrfjprogdll.so    LICENSE.txt        nrfjprog_release_notes.txt
jlinkarm_nrf51_nrfjprogdll.h    libjlinkarm_nrf52_nrfjprogdll.so    nrfdfu.h           QspiDefault.ini
jlinkarm_nrf52_nrfjprogdll.h    libjlinkarm_nrf91_nrfjprogdll.so    nrfjprog
jlinkarm_nrf91_nrfjprogdll.h    libjlinkarm_unknown_nrfjprogdll.so  nrfjprogdll.h
jlinkarm_unknown_nrfjprogdll.h  libnrfdfudll.so                     nrfjprog.h

And running nrfjprog from inside /opt/nrfjprog works fine. Can you confirm that installing v10.4.0 works on Ubuntu?

Anyway, I reverted to nrfjprog v10.3.0 (which installs without issues using dpkg as decsribed above) and updated successfully to 0.7.0-29.alpha using the included mdm_dfu tool. However, I am still unable to update to either v1.0.0 or v1.0.1 using the Programmer application.

2019-10-10T11:30:01.121Z ERROR Modem DFU failed with error: Error: Error occured when program. Errorcode: CouldNotOpenDevice (0x4)
Lowlevel error: NRFJPROG_SUB_DLL_COULD_NOT_BE_OPENED (ffffff69)

Are there any CLI tools I can use instead? Anything I can do to understand what the Programmer application is having trouble with?

Try installing nrfjprog v10.4.0, see this link, and see if that helps.

If that does not work either, you might need to update to another version first, before then updating to v1.0.0 / v1.0.1

E.g. try to update to 0.6.8-131.alpha , or 0.7.0-29.alpha first, and then v1.0.0 / v1.0.1

Older versions can also be found here: https://www.nordicsemi.com/Products/Low-power-cellular-IoT/nRF9160/Download#infotabs. Note that the pre-v1.0.0 versions need to use the mdm_dfu tool (included in the zip) for the update.

Hi Sigurd,

No other apps are running.

Hi,

You can get this error if you have the device connected to another nRF Connect App (like the LTE Link Monitor) as well as the Programmer app. Please close all other nRF Connect apps before updating the modem.

Hi Amanda,

It's a DK. This is the information from the back of the DK:

I tried erasing the chip, but the problem persists.

Hi Fredrik,

Is it a custom board or a DK?

If it's a DK, what version of the DK are you using?

You could try to erase the chip (nrfjprog -e) before programming modem fw 1.0.1.

Hi Amanda,

Yes, my nRF Command Line Tools are up to date. Just to make sure, I downloaded and installed them again, but I am still unable to update the modem firmware.

$ nrfjprog --version
nrfjprog version: 10.3.0
JLinkARM.dll version: 6.44e

I am able to successfully flash applications to the nRF9160 using the nRF Connect programmer. The at_client sample application works fine with the modem firmware currently on the board. It's just the modem update process that's not working.

Hi Fredrik,

Did you update to the latest 'nRF Command Line Tools'?

Please refer to this tutorial.
