Hi Bros:
How to open Tegra X1 DSI display port A, I would like to display both HDMI and DSI. Now, I have enabled the DSI panel-a-wuxga-8-0 in the device tree, and then the DSI and HDMI display are problematic. This can not correctly enable the DSI port, or there are other steps that are not done. Who has debugged the experience of this model, thank you for sharing.
Hi shrambo,
What is DSI “display port A”? Since you’ve enable DSI panel-a-wuxga-8-0 in your dts, I guess the current status for you is DSI not enable and HDMI works. This may come from panel-selection from board-panel.c
Please check if anything wrong there.
Hi WayneWWW:
In the file, I chose the 1200x1920 panel, but I configured in the device tree is 1920x1080 @ 30Hz, and I also confirmed that the settings are valid, I used two display devices, HDMI display normal, but the DSI port measured out Data is not correct, I guess there is a problem with the data source, but I can not determine whether HDMI and DSI are homologous (whether dc-> powergate_id is the control video source from DisplayA and DiaplayB)? I do not know where to go from the investigation, can you give me some suggestions? Thank you
Hi shrambo,
Please paste the dmesg with only DSI plugged. You error also happens when DSI panel works alone, right?
Hi Wayne：
My DSI output is actually achieved through dsi2lvds conversion chip, the following is my dmesg information:

Do you use a customized board?
Hi shrambo,
Have you clarified the cause and fixed the problem?
Any further information can be shared?
Thanks
