Using normal nrfjprog --program <hexfile> -f NRF91, will program the application flash.

For flashing the modem firmware, use nRF Programmer app. Or use a python pynrfjprog script, e.g. as shown in this post.

Hi Sigurd,

Thank you for prompt reply.

What I concerns is how to update firmware using JTAG/SWD. On the Dev board, there is USB J-Link, which will be able to recognize which flash area (modem or modem-app) to download magically. If we use SWD to update, it will only access modem-app area?

Thank you,

David

Yes, and with pynrfjprog. And Modem FOTA(Firmware Over-The-Air)(e.g. over HTTP) when that is released soon.

[quote userid="82485" url="~/f/nordic-q-a/53792/firmware-update-for-nrf9160-merged-hex/217586"]Does the Modem code share the same flash with modem application code (generated with Segger compiler as merged hex)?[/quote]

No. The modem uses it's own dedicated flash for storing the modem firmware. See the figure at this link.

Hi,

No, the merged.hex includes the application + spm (+ mcuboot if enabled).
