&spi4 {

    status = "okay";

    sck-pin = <8>;

};

please give any suggestion.

previously I build nrf5340dk_nrf5340_cpuapp(application core). 

then try to  build nrf5340dk_nrf5340_cpunet(network core), but build is not working some issues coming please any suggestion below error.

 

need to add any configuration?

need to change board overlay?

please give suggestion

Hi,

 

The network core has different peripherals than the application core, as seen here:

https://infocenter.nordicsemi.com/topic/ps_nrf5340/chapters/memory.network/netmem.html?cp=3_0_0_5_2_0#net_instantiation

 

Please note that the SPIM0 is a shared instance, meaning that it cannot be enabled simultaneously with other instances (like UART0/TWIM0/etc).

Are you certain you want to run this on the network core?

 

Kind regards,

Håkon

yes....i trying to change UART0 pin and that pin assign to others.

i am trying to interface MCP2515 CAN device  using SPI,  get data from input then send to BLE(Bluetooth) mobile app) 

this is my intention. so i am trying to build in Network core option(nrf5340dk_nrf5340_cpunet ) its not build.

It is the application core that usually handles data, so I would recommend that you add this sensor in the application core instead of the network core.

 

Kind regards,
