DEPRECATED: Updated Linux drivers for the ATWILC1000/ATWILC3000 products are located at https://github.com/linux4microchip/linux/tree/master/drivers/net/wireless/microchip/wilc1000. To simplify development, the legacy Linux4WILC was merged into the Linux4Microchip repo where driver development continues (Please refer latest ATWILC1000/ATWILC 3000 Wi-Fi Link Controller Linux User Guide) Driver code for Microchip ATWILC Wireless Devices (ATWILC1000 & ATWILC3000)

WILC3000 : Failed reset after firmware loaded #118

Open guilig opened 3 years ago

guilig commented 3 years ago

Hello,

We have a custom board based on iMX6 with Wilc3000 link by SPI. Kernel is 5.4

Our devicetree is : &ecspi3 { pinctrl-names = "default"; pinctrl-0 = <&pinctrl_ecspi3_wilc>; status = "okay"; num-cs = <1>; cs-gpios = <&gpio4 12 GPIO_ACTIVE_LOW>;

wilc_spi@0 {
    compatible = "microchip,wilc1000", "microchip,wilc3000";
    spi-max-frequency = <24000000>;
    reg = <0>;
    irq-gpios = <&gpio4 24 GPIO_ACTIVE_HIGH>;
    reset-gpios = <&gpio4 22 GPIO_ACTIVE_HIGH>; 
    chip_en-gpios = <&gpio4 23 GPIO_ACTIVE_HIGH>;
    status = "okay";
};

};

After load the firmware on the wilc, the driver shows this error :
