nrfprog for ARM architecture

[jdinh0608]

Hi,

We 're currently using an ARM SOM that will run Yocto Linux from NPX for our current project. We have the nrf52840 connect to this SOM via USB, and we want to be able to firmware upgrade the nrf52840 over USB in this environment. We can force the nrf52840 to go into serial DFU and detect it on Yocto's side with no issues. The problem now is that we want to use nrfprog to carry out the flashing/upgrading, but nrfprog isn't compiled for ARM architecture. 

Does anyone know if there is an ARM Linux binary for nrfprog? If not, does dfu-util work with SDFU? Or any potential solutions for this would be helpful.

Thanks,

Jon

If you want the ARM SOM to be the DFU Controller, then I would recommend taking a look at this GitHub Repo

https://github.com/jimmywong2003/nrf-slim-serial-uart-dfu-host-c-code

You should be able to use this to perform DFU of the NRF52840 from the ARM SOM.

Best regards

Thank you for the suggestion. After further investigation, we found out that nrfutil does work on ARM architecture. And we were able to successfully perform a DFU using our ARM SOM
