Other Parts Discussed in Thread: SK-AM62,
Ti export
My AM6254 board is designed based on SK-AM62 EVM, SDK is ti-processor-sdk-linux-rt-am62xx-evm-08.03.00.19-Linux-x86-Install.bin,
enable OLDI interface step is below:
1.Modify arch/arm64/boot/dts/ti/k3-am625-sk.dts, SK-AM62 EVM dts default is not enable OLDI interface, so i add
/ {
...
display0 {
//compatible = "nlt,nl192108ac18-02d";
compatible = "rocktech,rk101ii01d-ct";
backlight = <&lcd_bl>;
pinctrl-names = "default";
pinctrl-0 = <&lvds_enable_pin>;
enable-gpios = <&main_gpio1 19 GPIO_ACTIVE_HIGH>;
port {
lcd_in0: endpoint {
remote-endpoint = <&oldi_out0>;
};
};
};
...
};
&dss {
status = "okay";
};
&dss_ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
oldi_out0: endpoint {
remote-endpoint = <&lcd_in0>;
};
};
};
2.copy arch/arm64/boot/dts/ti/k3-am625-sk.dtb to boot device /boot/
3.reboot My board with new dtb.
4.login arago terminal,check /sys/class/drm/card0-LVDS-1/ exist， register sucessful see attachment boot log
5.check OLDI interface output by digital oscilloscope , and do not have signal
do i miss something? how to enable oldi interface ,
thx
