Radxa Zero Usb acessory Mode?

Radxa Zero, supports usb acessory mode ?
I’m trying to connect my board to my car with aagateway ( https://forum.xda-developers.com/t/android-4-1-proxy-gateway-for-android-auto.3813163/ ), thats needs usb acessory mode, i know thats LineAgeOS supports this mode, but don’t know if the radxa zero supports.
It already works with tv stick mk809IV.
Thanks ( sorry English is not my language )

If using upstream Linux on the board, it needs to have this patch (mine or an equivalent) else the board is being forced to host mode: https://patchwork.kernel.org/project/linux-amlogic/patch/20230127103913.3386435-1-christianshewitt@gmail.com/

If using Android or something with the 4.9 vendor kernel … no idea (someone else’s problem) :slight_smile:

Hi, I was compiling the lineageos from source, and it’s exactly the 4.9 kernel, so I stopped compiling and went to look at the source code and found this in g12a_s905y2_radxa0.dts ,

&dwc3 {
status = “okay”;

&usb2_phy_v2 {
status = “okay”;
portnum = <2>;

&usb3_phy_v2 {
status = “okay”;
portnum = <0>;
otg = <1>;
gpio-vbus-power = “GPIOH_6”;
gpios = <&gpio GPIOH_6 GPIO_ACTIVE_HIGH>;

&dwc2_a {
status = “okay”;
/** 0: normal, 1: otg+dwc3 host only, 2: otg+dwc3 device only*/
controller-type = <3>;

I’ll change the controller-type to 0 and see what happens.

Thanks for the info.
