Hi again, I seem to have got it working now. This node, in nrf9160dk_nrf52840/nrf9160dk_nrf52840.dts, must be disabled:

vcom0_pins_routing: switch-nrf91-uart1 {
	compatible = "nordic,nrf9160dk-optional-routing";
	control-gpios = <&gpio1 14 GPIO_ACTIVE_LOW>;
	status = "disabled";
};

This must be done for the image flashed to the nrf52840, as it controls alternate routing.

Hi Øivind,

Is there a test to see if port P0.26 is available?

Thank you for all your assistance.
Kind regards,

Hi Øivind,

P0.26 is not available, whether nrf9160dk_nrf9160 or nrf9160dk_nrf9160_ns.

The P0.26 port is invalid regardless of the DK board version

Thank you for all your assistance.
Kind regards,

I'm sorry, could you clarify, does P0.26 work when you build for secure? When the board is "nrf9160dk_nrf9160" and not "nrf9160dk_nrf9160_ns".

0.8.5 is an old engineering sample of the nRF9160, so it's taking a little while for me to procure a board to test this on.

Hi Øivind,

I used the method you said to test that P0.26 is still not available, could you test it yourself?

Thank you for all your assistance.
Kind regards,

Hi Øivind,

The above image is from the development board schematic

I test the pins P0.6 P0.7 P0.8 P0.9 were ok.

Thank you for all your assistance.

Does the button work when you build for secure? If it works in a secure build, try adding a folder named "child_image" to your application, and add a file called "spm.conf" to this folder, containing the line "CONFIG_SERIAL=n". Then see if it works for non-secure.

Hi,

That should work. You connect a button to P0.26 and click it, and get no response from the sample? Are you able to make the button work on other pins?

By the way, where is that image of the solder bridges from?
