nRF5340 Shared Peripherals between APP and NET cores

Hello,

The product specification for the nRF5340 peripheral chapter here mentions "The application core peripherals are accessible from the network core".

However in the device tree for the CPU there is only one memory mapped node for i2c0,spi0,uart0. 

does this mean if nodes are added and zephyr is properly configured, the network CPU can access the APP CPU peripherals such as QSPI or I2C_3 for example.

  • Hello, Anthony!

    The product specification does indeed mention that. However, I had a quick gander at how the RF5340 network core is defined in NCS and I couldn't find any reference to the application core peripherals. This means that it likely isn't trivial to add support for these, but I'll check with the developers whether that's the case or not!

    Best regards,
    Carl Richard
