Issues Configuring Two SPI Masters

[Tania V]

Hi Nordic team,

Hi Nordic Team,

We are trying to configure two SPI masters. It works when I use any single SPI (only one), but when I add the second SPI, I encounter issues. 

Do you have any recommendations or suggestions on how to resolve this?

Note: 2.5.0 SDK

&pinctrl {

    spi_master_default: spi_master_default {

        group0 {

            psels = <NRF_PSEL(SPIM_SCK, 1, 8)>,  

                    <NRF_PSEL(SPIM_MOSI, 0, 8)>,

                    <NRF_PSEL(SPIM_MISO, 0, 7)>;

                     //bias-pull-up;

        };

    };

    spi_master_sleep: spi_master_sleep {

        group0 {

            psels = <NRF_PSEL(SPIM_SCK, 1, 8)>,

                    <NRF_PSEL(SPIM_MOSI, 0, 8)>,

                    <NRF_PSEL(SPIM_MISO, 0, 7)>;

                    low-power-enable;

        };

    };

Hello,

When you use pins for SPIM, you have to make sure that pins are used by other peripherals. PIn P0.09 and P0.10 is used for NFC pins. You need to check if these pins are used for other peripherals apart from SPIM.
