Thanks for you help. But i found it’s too difficult to find which is wrong in hardware and software,Especially when they are all newly developed. It would be great if there were mature LCD hardware. So I can easily identify where the mistake is in software.Can you tell me Which manufacturer’s product really works on TX2?
Please refer to this one in kernel source. This is the working panel on tx2 which is from Sharp.
Can you provide the LCD model? I want to buy a real object.
The model number is “LQ080M1SX01 5900037676” from Sharp.
In the dts file hardware/nvidia/platform/tegra/common/kernel-dts/panels/panel-s-wuxga-8-0.dtsi,
The device tree node hostlx/dsi/panel-a-wuxga-8-0 's status assign value “disable”.
For get the screen working, I need to assign status value to “okay” ?
Yes, panel-s-wuxga-8-0 should be set to “okay”.
