Odroid M2 16G

If there is anyone still running an older version of the kernel and the USB-C is working it would be helpful if I can get a copy of your rk3588s-odroid-m2.dtb.

I managed to get some USB-C functionality back by adding a device tree overlay.

 

cat odroid-usbc-fix.dts 
/dts-v1/;
/plugin/;

/* 1. Force the USB controller into Host mode */
&{/usb@fc000000} {
    dr_mode = "host";
    status = "okay";
    /delete-property/ usb-role-switch;
    /delete-node/ port;
};

/* 2. Target the specific USB3 Type-C regulator by its absolute path */
&{/regulator-5v0-vcc-usb3-typec} {
    regulator-always-on;
    regulator-boot-on;
    status = "okay";
};

/* 3. Target the USB3 Host regulator by its absolute path */
&{/regulator-5v0-vcc-usb3-host} {
    regulator-always-on;
    regulator-boot-on;
    status = "okay";
};

 

However this disables OTG and devices with strict udev switching timing requirements fail to switch. So my QHY CCD camera is correctly detected as a westbridge device and udev / fxload commences loading the firmware but the power to the device is toggled and the firmware load fails as a result.

If I plug the QHY CCD in to the USB-C port via a powered USB-C hub then everything works fine. This works because the HUB is providing constant power.

So there appears to be a lot of difference between the Radxa USB-C and Odroid USB-C implementation that will need someone better at kernel stuff than me.
