C implementation of nrfutil, especially DFU over UART

[Tilak]

Dear Nordic Folks,

Greetings!
I see that nrfutil.exe dfu serial is used to update nRF52840 when using secure_bootloader_uart_mbr_pca10056.

Does Nordic provide c-code implementation of the following command:

nrfutil.exe dfu serial -p COMX -b 115200 -pkg app_dfu_package.zip

I see that 3 years ago the answer is no. Has this status changed now? Otherwise, we have a big overhead of porting nrfutil from python to C.

Kindly let me know your thoughts on this.

Thanks,
Tilak

HI,

you can refer to the example (https://github.com/jimmywong2003/nrf-slim-serial-uart-dfu-host-c-code)

Thank you very much Jimmy for your prompt response. It looks like the link that you have provided works/tested on SDK 15.2.0 with nRF52832 and the nrfutil v3.5 and v4.0. We are planning to use SDK 16.0.0 with nRF52840 and the latest nrfutil 6.0.1. Do you foresee any potential problems that we should look out for?

Kindly let me know your thoughts on this.

Thanks,
Tilak
