Hello,
I’am testing the IMX8 SOM on Apalis eval board.
I have enabled SPIDEV on device tree as follow
&lpspi0 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_lpspi0>;
#address-cells = <1>;
#size-cells = <0>;
cs-gpios = <&lsio_gpio3 5 GPIO_ACTIVE_LOW>;
spidev0: spi@0 {
compatible = "toradex,evalspi";
reg = <0>;
spi-max-frequency = <4000000>;
};
};
we realized the driver use gpio chip select instead of native CS (delay introduced between byte).
How to force usage of SPI native chip select?
Best regards
