Hi,
I have tried flashing Jetpack 5.15 through building from sources to Jetson Orin Nano, it’s getting flashed but shows a blank screen when connected to DP monitor(I have tried different monitors as well), the display shows the boot splash screen but after that it shows only out of range, When flashed from sdk manager the display port is working without any issues.

Note: I haven’t modifed the sources I just compiled and tried to flash.

Can someone help me fix this issue ?

Thanks in Advance.

Have you tried other kind of monitors?

Hi @WayneWWW,
I tried around 3 different Displays (LG, HP) with DP and even tried a DP to HDMI convertor and still facing this issue.

Please access your board with serial console first and share /var/log/xorg.0.log with monitor connected case.

Hi @WayneWWW ,
I was able to take the Log from serial console. I am attaching it here

Since I am stuck with this issue after flash I am not sure how to login and get “/var/log/xorg.0.log”

Hi,

Your system is in recovery boot now. Please check this to recover from it and dump log again.

Hi @WayneWWW ,
I have chnaged the OS chain A status → Normal, Now its using Direct boot instead of Recovery boot.

It is not blank screen issue. It is your system totally cannot boot up now so of course the monitor will not light up.

Are you able to reflash the board?

10

Hi @WayneWWW ,
Yes I am able to reflash the board.
I am able to boot without any issues when I flash from SDK manager, But when I flash from the sources I get this issue.

11

Could you give some more detail about what does that mean “flash from sources”?

Please try to be more clear about what did you do there. Otherwise we totally don’t know how to answer your question.

Hi @WayneWWW ,
I meant I downloaded all the source files from the Jetpack Archive here, Compiled the sources, I followed the steps here to compile the kernel sources.
NOTE: I didn’t customize the kernel just downloaded it, compiled it and flashed it.

The document link you posted is a very old version of document. You better using the same version matching your your source code first…

Also, please do not just tell me “I followed the document”. Show me what you did in your terminal.

Hi @WayneWWW ,
I am attaching the terminal command I followed here
Command_Used.txt (4.5 KB)

I am attaching the output of the flash.sh here
Terminal_FLash_Output.txt (104.2 KB)

the flash command you tried didn’t flash anything to the external drive exactly.

Flash.sh cannot flash external drive. Please follow document to use initrd flash tool.

Hi @WayneWWW ,

  1. Correct me if I am Wrong I used the Same flash.sh script to flash my jetson Xavier NX(to SD card) I didn’t have any issues, Confused why its causing issue for Orin nano.
  2. I tried the to execute this sudo ./tools/kernel_flash/l4t_initrd_flash.sh jetson-orin-nano-devkit-super mmcblk1p1 and got the following error.
/home/htic/Kernel_Builds/jetpack5/Orin_nano/Linux_for_Tegra/tools/kernel_flash/l4t_initrd_flash_internal.sh --no-flash jetson-orin-nano-devkit-super mmcblk1p1

  1. Does initrd flash tool make some configuration one time programmable, Should I be cautious on any parameters?
  2. If there are any document to follow can you please share.

Just to be more precise here. initrd flash command is just put here and you just need to copy it.
