Rock 3A SATA over USB3

#1

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
