Unfortunately not.

However, with NCS v1.5.0, it is now possible to do full modem DFU over UART (if the application supports it).

So you should be able to update the modem FW using the fmfu_smp_svr sample in NCS v1.5.0.

Any possibility to program the modem firmware with nrfjprog? Could you guide me with the correct settings/flash addresses, etc for this?

I have another ticket open (neither nRF Connect nor pynrfjprog discovers my J-Link EDU Mini, but nrfjprog and J-Flash Lite works), so I'm not able to program modem firmware in the traditional ways (nRF program og python script).

Hi,

[quote user=""]mfw-pti_nrf9160_1.1.1[/quote]

This is a production test image, and not the full modem firmware.

It is a cut-down version of the full modem firmware, which can be used during production testing, but it does not have any signalling capability.

It does however have some extra features which are usefull for production testing.

But, when you are done testing, and before the product can be used, you must program a full modem firmware to the device.

There is some information on the production test image in the AT command reference guide.

Best regards,

Didrik
