Part Number: AM6548
Hi Ti,
We follow this thread to configure our usb0 and tried to bring up on our EVM board.
We modified k3-am654-base-board.dts as below, usb0 as peripheral and usb1 as host:
&main_pmx0 {
usb0_pins_default: usb0_pins_default {
pinctrl-single,pins = <
AM65X_IOPAD(0x02bc, PIN_OUTPUT, 0) /* (AD9) USB0_DRVVBUS */
>;
};
usb20_host_pins_default: usb20_host_pins_default {
pinctrl-single,pins = <
AM65X_IOPAD(0x02c0, PIN_OUTPUT, 0) /* (AC8) USB1_DRVVBUS */
>;
};
};
&dwc3_0 {
status = "okay";
};
&usb0_phy {
status = "okay";
};
&usb0 {
pinctrl-names = "default";
pinctrl-0 = <&usb0_pins_default>;
dr_mode = "peripheral";
};
&dwc3_1 {
status = "okay";
};
&usb1_phy {
status = "okay";
};
&usb1 {
pinctrl-names = "default";
pinctrl-0 = <&usb20_host_pins_default>;
dr_mode = "host";
};
However, usb has no response when plugin usb0 to my computer.
And there are also no kernel log.
If this setting has any problem?
I also can get some info from device node, but have no idea why usb cannot work.
Attached the boot log.
