问题:

spi0和spi1均无法枚举到设备节点

对dts修改如下：

@lbuque
驱动要配置SPI 导出User Interface。

有解决吗 我也碰到这个问题

[a892755772]

@whycan 能说的详细点吗 我也碰到这个问题 SPI在/dev上显示不出来

@a892755772
板级目录下config-5.4 文件使能 CONFIG_SPI_DEV

上面是盲打的，或许有误。

@whycan 感谢你的回复 你说的可能是CONFIG_SPI_SPIDEV 可是我已经设置了 但是不行。您能再看下吗

@a892755772

board.dts 也需要配置一下喔。

[a892755772]

@whycan 也按照文档配置了

https://wiki.stmicroelectronics.cn/stm32mpu/wiki/How_to_use_SPI_from_Linux_userland_with_spidev

&spi4 {
    pinctrl-names = "default", "sleep";
    pinctrl-0 = <&spi4_pins_a>;
    pinctrl-1 = <&spi4_sleep_pins_a>;
    status = "okay";
 
    spidev@0{
        compatible = "spidev";
        reg = <0>;
        spi-max-frequency = <4000000>;
    };
};

@whycan 感谢你的回复 我已经找到原因了
查看了 这个文件 out/t113/evb1_auto/longan/.sunxi.dts 我发现其实没有配置好
配置有两个地方需要改
