nRF52840 DK permanent hang during flashing

Hi,

We have a stability issue with nRF52840 DK after it has been upgraded to JLink DLL version V6.60e and firmware OB-SAM3U128-V2-NordicSemi compiled Jan 7 2019 14:07:15.
Please see the below scenario which typically reproduces this problem:


1) Start JLinkExe

16:36 $ sudo JLinkExe -if swd -speed 9600 -device NRF52840_XXAA -autoconnect 1

2) Start JLinkRTTClient to see logs from device

3) Start flash programming

sudo nrfjprog -f nrf52 -r --program nrf52840_xxaa.hex --sectorerase
ERROR: nrfjprog failed for an unknown reason. Run the same command again with
ERROR: argument --log, contact Nordic Semiconductor and provide the generated
ERROR: log.log file to them.

In step 3) the programming does not start and below error appears in JLinkExe:
****** Error: Communication timed out: Requested 12 bytes, received 0 bytes !


nrfjprog -i does not show any connected SWD device when this problem appears.

Rebooting PC with Linux with nRF52840 DK in such state causes that PC hangs on bootup. It's very problematic for us, since we are working remotely with this setup.
The only way to recover the nRF52840 DK is to physically disconnect it from USB and then reconnect.

Please let me know if there is some solution to this issue, because it's very problematic in our development.

  • Hi,

    You can try to first download and install the latest j-link from here:
    https://www.segger.com/downloads/jlink#J-LinkSoftwareAndDocumentationPack

    I am not familiar with Linux, but typically you should use the jlink configurator tool to update to the latest firmware, as seen in this reply for instance:
    https://devzone.nordicsemi.com/f/nordic-q-a/41192/where-to-download-j-link-ob-firmware-j-link-ob-sam3u128-v2-nordicsemi-170213-bin/225493#225493 

    Once that is done, you can also disable the DK to enumerate as a disk drive by calling MSDDisable as seen here:

    Remember to power cycle the DK for the change to have an effect. This should prevent the PC to hang during startup.

    Hopefully the above should make nrfjprog to work again and the PC to boot.

    Best regards,
    Kenneth

  • Hi,

    Thank you for the information.

    I've already updated to the newest JLin DLL version V6.64b.

    Firmware on DK has been automatically updated to  Firmware: J-Link OB-SAM3U128-V2-NordicSemi compiled Mar 17 2020 14:43:00, please see logs:

    10:08 $ sudo JLinkExe -if swd -speed 9600 -device NRF52840_XXAA -autoconnect 1

    in general it looks more stable but unfortunately the problem appeared again while attempting to program firmware:

    J-Link>
    ****** Error: Communication timed out: Requested 12 bytes, received 0 bytes !

    I will call MSDDisable and hope this will help.

  • I've just reproduced this problem again with MSDDisable previously called as you suggested and my laptop is still hanging on bootup, when such broken DK is attached to USB.

  • Just to try to narrow it down:

    - Is it just one DK, or all of them?
    - Have you by any chance cut the solder bridges to measure current at any time?
    - Do you have such problems if you use another PC (e.g. with windows)?
    - What version is it of the nRF52840-DK?

    Best regards,
    Kenneth

  • - Is it just one DK, or all of them?
    We have several DKs, please see details below.

    - Have you by any chance cut the solder bridges to measure current at any time?
    No.

    - Do you have such problems if you use another PC (e.g. with windows)?
    We have such problem on several PCs, Ubuntu 18.04. We do not use it with Windows.

    - What version is it of the nRF52840-DK?
    These have problems described in this issue, running on Ubuntu 18.04:
    * PCA10056 0.9.3 2017.44
    * PCA10056 1.0.0 2018.49

    On this one I cannot reprocuce this prolem so far, on Ubuntu 18.04:
    * PCA10056 2.0.0. 2020.2

    This one is running on Mac, had the same problems, but now it's working after upgrade to JLink V6.64b.
    * PCA10056 1.1.0 2019.26

    I also found out, that the issue does not appear when I close JLink connection and quit using "qc" command before flash programming.

  • So if I understand it correctly this worked on previous version of nrfjprog/jlink (do you know which one?), but the latest 10.7.0/6.64b this does not work anymore? Or is it only 6.60e that fails?

    It seems like conflict between jlink and nrfjprog, I can report it internally. Can you type nrfjprog --version just so I have that.

    Best regards,
    Kenneth

  • The problem appears on 6.60e as well. We didn't experience such issues some time before (maybe a year before) but I don't remember what version it was...

    Machine 1:

    $ nrfjprog --version
    nrfjprog version: 10.7.0
    JLinkARM.dll version: 6.64b

    Machine 2:

    $ nrfjprog --version
    nrfjprog version: 10.6.0
    JLinkARM.dll version: 6.64b

    Issue occurs on both machines like above.

  • Hi again, 

    Can you also run "nrfjprog" command with logging enabled? use --log and send us the log.log file?

    nrfjprog -f nrf52 -r --program nrf52840_xxaa.hex --sectorerase --log

    Thanks,
    Kenneth

  • It looks like Jlink have communication errors (read error) when connected to the device, maybe reducing clock speed can help, but this may be an SEGGER Jlink issue. I can in any case report it, let me know if you find a solution or workaround. You may also consider reach out to SEGGER, I think it would help if you knew version this worked on.

    Best regards,
    Kenneth

  • The only workaround I found is to close JLink connection using "qc" command before flash programming.

    Best regards,
    Krzysztof
