Missing spidev on Solidrun Hummingboard Pulse (iMX8)

garyg — Wed, 07 Aug 2019 11:27:27 GMT

When flashing the sdcard using the official provided Debian image Index of /IMX8/Debian/ on the Solidrun Hummingboard Pulse, I can't find any /dev/spidev*.

Following is the fsl-imx8mq.dtsi device tree file and I noticed the status is set to 'disabled'? I think a spidev node should be added here?

    ecspi1: ecspi@30820000 {
       compatible = "fsl,imx6ul-ecspi", "fsl,imx51-ecspi";
       reg = <0x0 0x30820000 0x0 0x10000>;
       interrupts = <GIC_SPI 31 IRQ_TYPE_LEVEL_HIGH>;
       clocks = <&clk IMX8MQ_CLK_ECSPI1_ROOT>,
           <&clk IMX8MQ_CLK_ECSPI1_ROOT>;
       clock-names = "ipg", "per";
       interrupt-parent = <&gpc>;
       status = "disabled";
   };

Hello Gary,

That depends on the schematics, please check the schematics of the Humming Board to see if the ECSPI1 it is use for SPIDEV. or it is based on other application. My advise also would be that you submit your question directly to the Solid Run Forum, here is the link:
