Hi ,
We have a customized RZG1E board with CIP 35. We enabled spidev in our board as below:
&pfc {
msiof2_pins: spi3 {
renesas,groups = "msiof2_clk", "msiof2_ss1", "msiof2_tx", "msiof2_rx";
renesas,function = "msiof2";
};
};
&msiof2 {
status = "okay";
pinctrl-0 = <&msiof2_pins>;
pinctrl-names = "default";
spidev@0 {
compatible = "renesas,spidev-r8a7745";
spi-max-frequency = <1000000>;
};
};
When we try to access the spi device connected on this bus chip-select (cs) pin is not making any transition(high to low).
