I have designed a custom board using the nrf54l10 chip (similar to nrf54l15). I want to use SPI to communicate with a sensor. So I assigned the pins P2.6 for SCK, P2.4 for MOSI and P2.2 for MISO. So, the commun SPI channel on the board is the SPIM00. However, using these pins and configuring my spi overlay, I am not being able to start the communication. SCK is not sending any signal. I have noticed if I change to SPIM20 channel and change SCK pin to P2.1 everything works fine.
What do i need to set to be able to use the SPIM00 channel?
I am using this library
#include <zephyr/drivers/spi.h>
overlay:
&spi00 {
compatible = "nordic,nrf-spim";
status = "okay";
pinctrl-0 = <&spi00_default>;
pinctrl-1 = <&spi00_sleep>;
pinctrl-names = "default", "sleep";
cs-gpios = <&gpio1 5 GPIO_ACTIVE_LOW>;
ads124s08: ads124s08@0 {
compatible = "vnd,spi-device";
reg = <0>;
spi-max-frequency = <1000000>;
};
};
&pinctrl {
spi00_default: spi00_default {
group1 {
psels = <NRF_PSEL(SPIM_SCK, 2, 6)>,
<NRF_PSEL(SPIM_MOSI, 2, 4)>,
<NRF_PSEL(SPIM_MISO, 2, 2)>;
};
};
spi00_sleep: spi00_sleep {
group1 {
psels = <NRF_PSEL(SPIM_SCK, 2, 6)>,
<NRF_PSEL(SPIM_MOSI, 2, 4)>,
<NRF_PSEL(SPIM_MISO, 2, 2)>;
low-power-enable;
};
};
};
