Using P0.04, P0.05, P0.06, P0.07 for SPIM on NRF9160 DK

Hi,

Have you tried scoping the pins using a logic analyzer to see how they behave?

By default, uart1 is used for TF-M logging, so you need to explicitly turn that off, as uarte1 is a shared peripheral with SPI1.

Set this in prj.conf: CONFIG_TFM_LOG_LEVEL_SILENCE=y

Kind regards,

Håkon

Yes, I did.

It's not so much an error that I'm seeing but the SPI communication is not working. On the older pins it works fine but on 4,5,6,7 it's not working. It's not working even after flashing the nrf52 with the device tree changes I sent

What errors are you receiving that indicates that it does not work?

I added the following overlay to hello_world example, built if for nrf9160dk@1.1.3/nrf52840, and flashed it but my SPI still isn't working

&led1_pin_routing { status = "disabled";}; // nrf9160 P0.02
&led2_pin_routing { status = "disabled";}; // nrf9160 P0.03
&led3_pin_routing { status = "disabled";}; // nrf9160 P0.04
&led4_pin_routing { status = "disabled";}; // nrf9160 P0.05
&switch1_pin_routing { status = "disabled";}; // nrf9160 P0.06
&switch2_pin_routing { status = "disabled";}; // nrf9160 P0.07
&switch3_pin_routing { status = "disabled";}; // nrf9160 P0.08
&switch4_pin_routing { status = "disabled";}; // nrf9160 P0.09

Hello,

The nRF9160DK has a nRF52840 acting as a board controller which means that LEDs and Buttons are controlled through this device. This is also explained in Board controller firmware under NCS nRF9160DK board files.

You will need to follow steps in the last link in order to make these pins available.

Kind regards,
Øyvind
