Full modem update configuration

[Praveen Deshmane]

Hi,

I want to do full modem update.

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/nrf9160/http_update/full_modem_update/README.html

My device is - nrf1960

nrf SDK version  - 1.9.1

I am not understanding how to do the following configuration. Please guide me.

On the nRF9160 DK, set the control signal from the nRF52840 board controller MCU (P0.19) to high to let the nRF9160 communicate with the external flash memory. 

I have through following link also. Still cant understand.

Best regards

Hello,

I am not understanding how to do the following configuration. Please guide me.

What part do you not understand? To change the board controller, just build the Zephyr hello_world sample for example, and choose nrf9160dk_nrf52840 as board. You need to put

&external_flash_pins_routing {
    status = "okay";
};

in the .overlay file before building and flashing. Then flash it to the nrf52840 chip. After that you should be able to access the P0.19 to enable the external flash communication.

Can you show the build log?

Hello Hakon,

Sorry for replying late. I was busy in other tasks. I really appreciate your time.

What are you trying to build here? I told you to build the Zephyr hello_world sample or similar. This one seems to be using a whole bunch of stuff that is not compatible with nrf52840. Build the hello_world sample for nrf9160dk_nrf52840, and try again.
