Peripheral USB-C[edit | edit source]
SBC ORCA[edit | edit source]
In SBC Orca two USB-C ports were mounted, that is:
- USB-C 1
- USB-C 2
USB-C 1[edit | edit source]
The USB-C 1 port is used to power-supply the board and for the transfer of data by Downstream-Facing Port (DFP) mode. The connector that is inserted in this port works in both side.
In U-Boot you can use this port only to power-supply the board and not for data transfer. In Linux you can use this port for data transfer.
For more information, refer to the example in USB1 OTG.
USB-C 2[edit | edit source]
The USB-C 2 port is used for data transfer. The connector that is inserted in this port works in both side.
In U-Boot you can use this port to transmit data with an external device, Downstream-Facing Port (DFP) mode, and to use the UUU functionality of NXP. In Linux you can use the Dual-Role Data mode (DRD).
For more information, refer to the example in USB2 OTG.
Device tree configuration in ORCA SOM[edit | edit source]
From imx8mp-mito8mplus-cb1001.dts:
&iomuxc {
pinctrl_ptn5150: ptn5150grp {
fsl,pins = <
MX8MP_IOMUXC_GPIO1_IO00__GPIO1_IO00 0x156
MX8MP_IOMUXC_GPIO1_IO14__GPIO1_IO14 0x16
>;
};
...
...
extcon_usbotg2: typec@3d {
compatible = "nxp,ptn5150";
reg = <0x3d>;
int-gpios = <&gpio1 00 GPIO_ACTIVE_LOW>;
vbus-gpio = <&gpio1 14 GPIO_ACTIVE_HIGH>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_ptn5150>;
status = "okay";
};
...
...
