SPI Pins in nrf9160dk_nrf9160_common.dts

[Canastra]

Hi

in Zephir nrf9160dk_nrf9160_common.dts the SPI pins are defined

&spi3 {
compatible = "nordic,nrf-spim";
status = "okay";
sck-pin = <19>;
mosi-pin = <18>;
miso-pin = <17>;
};

But in the scematic of nRF9160DK an SPI is defined on following PINs.

P0.11 MOSI

P0.12 MISO

P0.13 SCK

Is there a reason to define useless pins?

Hello RetoFelix, 

I'm sorry, but I can’t really follow you... 

Is there a reason to define useless pins?

What do you mean by "useless" pins?

And what has the pin assignment of SPI3 to do with the nRF91_EXT_MEM interface? Please elaborate!

Regards,

Markus

Hi Markus

The Board description should descripe the real board.

On the real board an SPI is usefull for an SPI EEPROM on P0.11, P0.12, P0.13.

In the Board description the SPI is connected to P0.17, P0.18, P0.19. I think this Pins are useless.

Before I can use the SPI I must add an overlay to move the SPI Pins.
