where to find/download mfw_nrf91x1_2.0.1 .hex /.bin (not updates) for nrf9151

stepen

Hi there,

We have been working on nRF9151DK (dev kits) containing the mfw_nrf91x1_2.0.1 modem firmware.  Now we have some custom prototype boards ready (same SiP obviously) and we noticed they were running mfw-pti_nrf91x1_2.3.5. We could see from the support site that this version "does not include any protocol signaling capabilities" (which might be the reason why there is no comms available). So my question is where do we find the 'older' full version mfw_nrf91x1_2.0.1 .hex/.bin. I can only see upgrade/.cbor files on the site not full .hex/.bins for easy programming ?

I'm probably looking in the wrong place, so any hints would be nice. (It's a NCS v2.9.0, Ubuntu/WSL we run).

Thanks in Advance 

- Stefan

    Hi Stefan,

    You can download it on the nRF9151 product page (link). Go to the Download and there you can choose your version of the modem firmware.

    To program the modem firmware to the device, follow our guide "Programming nRF91 Series DK firmware". It contains explanation on how to flash the modem firmware on the nRF91 devices using the "Programmer" application. I just want to get your attention on the fact that you don't unzip the file you downloaded. You have to upload the whole zip to the programmer.

    It is also possible to use nRF Util directly if you need a less manual process. The command is "nrfutil device program --firmware path/to/mfw_nrf91x1_2.0.1.zip".

    If you have more questions, feel free to ask!

    Best regards,

    Simon D-M
