Configuring spi1 on the r3

Default
1

Hi everyone,

Was wondering if anyone has been successful in configuring a device for the second SPI controller on r3. I made the following additions to the device tree source

&pio {
	spi1_pins: spi1-pins {
		pins = "PE9", "PE7", "PE10", "PE8";
		function = "spi1";
	};
			
	spi1_cs_pins: spi1-cs-pins {
        pins = "PE7";
        function = "gpio_out";
	};
};


&spi1 {
	status = "okay";
	
	pinctrl-names = "default";	
	pinctrl-0 = <&spi1_pins &spi1_cs_pins>;
	num_chipselect = <1>;
	cs-gpios = <&pio 4 7 GPIO_ACTIVE_HIGH>;
	
	spidev@0 {
            compatible = "spidev";
            reg = <0>;   
            spi-max-frequency = <0x2625a00>;
   	};
};

I do get the spidev device in spidev device file in /dev and loopback tests using this rm-hull’s spidev-test script on githhub and a jumper wire between PE10 & PE8 do work. But interfacing with an spi device (in my case the RFID-MFRC522) doesn’t work. My current guess is I haven’t configured the chip select i.e PE7 correctly. Am I missing something?? Is it necessary configuring PE7 for the f1c200s ?

Any help is very much appreciated.
