Rock 3A SATA over USB3

Hi, We connect sata through USB 3.0 related pin. But it does not recognizes. How can we change dtbo to change mux from USB3 to SATA ? How to modify device tree?

Thanks…

usb 3

/* sata1 is muxed with the usb3 port */
&sata1 {
status = “disabled”;
// status = “okay”;
};

/* usb3 controller is muxed with sata1 */
&usbhost_dwc3 {
status = “okay”;
};

/* usb3 controller is muxed with sata1 */
&usbhost30 {
status = “okay”;
};

sata

/* sata1 is muxed with the usb3 port */
&sata1 {
// status = “disabled”;
status = “okay”;
};

/* usb3 controller is muxed with sata1 */
&usbhost_dwc3 {
status = “disabled”;
};

/* usb3 controller is muxed with sata1 */
&usbhost30 {
status = “disabled”;
};

sata over pcie

/* sata2 is muxed with the pcie2 slot*/
// /delete-node/ &sata2;
&sata2 {
target-supply = <&pcie20_3v3>;
// status = “disabled”;
status = “okay”;
};

&pcie2x1 {
status = “disabled”;
};

just enable combophy

and disable the device you dont use and enable the other and visa versa
