[StefanBeelen]

Cannot update modem (nrf9160) with "nrf connect 3.8.0"

Modem DFU failed with error: no matching trait found

Installing older versions eg. 3.7.1 -> have issue with Programmer v2.0.0

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:

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, because 3.7.2 was not needed and not released for these).
2. After starting nRF Connect for Desktop 3.7 a prompt will come up about the 3.8 upgrade. Click “No” on this.
3. 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”.
4. 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”.
5. 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. 

[Marte Myrvold]

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
