Hi Charlie,

This definitely helps. The "nrf9160_pca20035_modem_upgrade_over_serial.py" example comes very close to what I need. However, it requires two serial ports. Unfortunately, I will only have one serial port available. I will have the J-Link adapter connected. So, I have an SWD interface and a serial port available. Also, there will be application code and a bootloader in the flash on the nRF9160. This example seems to write a DFU server into the flash which most likely erases or overwrites what was in there before. I need a script that behaves like the Nordic tool which updates the modem firmware with a J-Link adapter and leaves the existing application code and bootloader intact.

Do you have a Python script that does that?

Thanks,

Johnas

Hi Johnas,

Can NordicSemiconductor/pynrfjprog: Python wrapper around the nrfjprog dynamic link library (DLL) (github.com) satisfy your needs?
