nrf connect 3.8.0 & Programmer v2.0.0 -> Update modem (Modem DFU failed)

Hello Marte,

it's a custom board with SWD interface. As I said with nRFConnect 3.7 it is working. So I will stay on this older version and wait fior a fix.

Best regards,

Peter

Hi,

Is your device a Thingy:91 or nRF9160 DK? If it is a Thingy, are you trying to update through USB or using an external debug probe? What are you using as external debug probe if that is the case?

The developers are working on fixing this, but in the meantime there are two possible workarounds you can try:

Downgrade nRF Connect for Desktop to 3.7 and installing app versions compatible with 3.7:

Download the latest 3.7 version of nRF Connect for Desktop from https://www.nordicsemi.com/Products/Development-tools/nRF-Connect-for-desktop/Download?lang=en#infotabs (for macOS this is 3.7.2, for Windows and Linux 3.7.1, because 3.7.2 was not needed and not released for these).
After starting nRF Connect for Desktop 3.7 a prompt will come up about the 3.8 upgrade. Click “No” on this.
In the Settings, click on “Add source”, enter the URL http://developer.nordicsemi.com/.pc-tools/nrfconnect-apps/3.7-apps/apps.json and click “Add”.
Back in the list of all apps, all apps should show up twice now, one with “official” below them and one with “3.7 compatible apps” below them. If you want to hide the incompatible versions, click on “Filter” and deselect “Official”.
Install the apps you need in the old versions and use them.

Use nrfjprog in a shell to perform the upgrade:

nrfjprog --program <path-to-fw-zip> -s <serial number> --verify

Best regards,

Marte

I have done a downgrade to JLink version 6.88a but this does not solve the problem. The behaviour is still the same on my Windows 10 x64 PC. With nRF Connect V3.7.1 a modem firmware update is no problem.

Hi,

Thank you for informing us that you are still seeing this in v3.9.0.

Could you try downgrading JLink to version v6.88a? The version of JLink that is bundled with the latest version of nRF Command Line Tools causes errors in nRF Connect for Desktop. This was not fixed in v3.9.0, and our developers are still working on a fix, but in the meantime they suggest downgrading JLink as a temporary solution.

Best regards,

Marte

I have the exact same problem version 3.9.0 & Connect v2.0.0 did not work. Downgrading to Connect v3.7.1 and Programmer v1.4.11 solves the issue.

Edit: Using Windows, target is Thingy91.

Hi,

We have just released v3.9.0 of nRF Connect for Desktop, which includes fixes to make enumeration more robust and increase the timeout when enumeration takes a long time. The version is not on the download page yet, but you can update to it directly in the app, and you can find the release and release notes here nRF Connect for Desktop releases.

The developers have also found that the JLink version that is bundled with the latest version of nRF Command Line Tools causes errors in nRF Connect for Desktop. They are working on a fix for this as well, but a temporary workaround is to downgrade JLink to a known working version, v6.88a, from https://www.segger.com/downloads/jlink.

Best regards,

Marte

Hi,

I am happy to hear that you are able to get it working with 3.7.1 again!

I will let you know when I have any updates from the developers regarding this issue.

Best regards,

Marte

Yes, I was able to update the modem with nRF Connect for Desktop 3.7.1 before I updated to 3.8.0.

Now I followed your instructions to downgrade to 3.7.1. and have installed the Programmer app version comatible with 3.7.1.

With the 3.7.1. version it is working again.

Hi,

Were you able to update the modem with nRF Connect for Desktop 3.7.1 before you updated to 3.8.0?

I have reported this internally. In the meantime, you can try to downgrade to 3.7.1 and install app versions compatible with 3.7.1:

Download the latest 3.7 version of nRF Connect for Desktop from https://www.nordicsemi.com/Products/Development-tools/nRF-Connect-for-desktop/Download?lang=en#infotabs (for macOS this is 3.7.2, for Windows and Linux 3.7.1).
After starting nRF Connect for Desktop 3.7 a prompt will come up about the 3.8 upgrade. Click “No” on this.
In the Settings, click on “Add source”, enter the URL http://developer.nordicsemi.com/.pc-tools/nrfconnect-apps/3.7-apps/apps.json and click “Add”.
Back in the list of all apps, all apps should show up twice now, one with “official” below them and one with “3.7 compatible apps” below them. If you want to hide the incompatible versions, click on “Filter” and deselect “Official”.
Install the apps you need in the old versions and use them
