Hi @WayneWWW ,
Here below are the two files, you have asked for:

full_boot_log.txt (61.1 KB)
extracted_device_tree.txt (413.7 KB)

Hi,

Could you download a default BSP again and flash it to your board just with eeprom change?

  • cvb_eeprom_read_size = <0x0>

Currently, I saw it is still based on your custom DTB. Though it seems looking good.
However, DCE fw has its own dtb which I feel it is not same as the default one. A clean setup might be needed.

Hi, @WayneWWW , now, I did with only eeprom change and set a stattic ip , thats all. But still not display output.

  1. I just saw that your dts is changed. It is using “tegra234-p3767-0004-p3768-0000-a0.dts” now but previous one is p3767-0003 one. Did you ever change the module here? or just because previous one was customized by you so something went wrong before?

  2. Please also dump the result of xrandr and xorg log of current situation.

hi @WayneWWW
Previously, I was using GitHub - VC-MIPI-modules/vc_mipi_nvidia: Vision Components MIPI CSI-2 driver for NVIDIA Jetson Nano, Xavier NX, AGX Xavier, TX2 and Orin Nano, Orin NX , which take the l4t and integrate the camera driver thats all. There I chossed Jetson Orin Nano Devkit.

Now I directly use Jetson SDK Manager. In both case, the devices start and works normally whre I only changes epprom and set ip address. Could not create xrandr_log because its emtpy.

jetson@ubuntu:~$ export DISPLAY=:0                                            
jetson@ubuntu:~$ xrandr                                                       
No protocol specified

Hi,

The xorg log indicate it is in DP mode now. But it cannot detect any monitor connected to it.

Do you have NV devkit that can validate your monitor is really fine when using on NV devkit?

28

Hi @WayneWWW, Yes, I validated with NV devkit and monitors works fine.

Then please review the hardware design of the custom board.
