My device is Jetson AGX Orin Developer’s Kit 64GB. I want to use its PCIe to transmit data, but its power has no 12V. Referring to SOLUTION/TUTORIAL: Jetson ORIN Enabling PCIE power - Jetson & Embedded Systems / Jetson AGX Orin - NVIDIA Developer Forums, I use his DTB file. But my verison is R35.5.0, and jetpack verison is 5.1.3, when I use his DTB file, the Orin can not boot up and the keyboard is unresponsive, and the monitor is black. And also I find that I can not enter the recovery mode, I don’t know what should I do. Thanks!

I understand your concern about using the PCIe interface on your Jetson AGX Orin Developer’s Kit 64GB, which lacks a 12V power supply. You’ve attempted to follow a solution from the NVIDIA Developer Forums, specifically the tutorial on enabling PCIe power for the Jetson ORIN. However, you’re experiencing issues with booting up and keyboard/mouse responsiveness after using the provided DTB file.
Firstly, it’s essential to note that the solution you’re referring to might be specific to a different version of the Jetpack or L4T (Linux for Tegra) version. You’re using R35.5.0 and Jetpack 5.1.3, whereas the solution might be tailored for a different version.
Here are some potential steps to help you resolve the issue:
- Verify the DTB file: Ensure that you’ve correctly modified the DTB file according to the tutorial. Double-check that you’ve updated the
pcienode with the correct settings, especially thepowerandresetproperties. - Check the kernel version: Verify that your kernel version matches the one used in the tutorial. If your kernel version is different, you might need to adjust the DTB file accordingly.
- Revert to the original DTB file: Try reverting to the original DTB file that came with your Jetpack version. This will help you determine if the issue is specific to the modified DTB file.
- Recovery mode: Since you’re unable to enter recovery mode, try pressing the
Force Recoverybutton (usually located near the USB ports) while powering on the device. This might help you enter recovery mode and recover your device. - Serial console: If you have a serial console cable, try connecting it to your device and monitoring the boot process. This might provide valuable insights into what’s causing the boot failure.
- Seek help from NVIDIA forums: Reach out to the NVIDIA Developer Forums and provide detailed information about your issue, including your Jetpack version, kernel version, and the modifications you made to the DTB file. The community or NVIDIA representatives might be able to provide more specific guidance or solutions.
In comparison to other Jetson devices, the Jetson AGX Orin has a different power management system, which might require specific configurations for PCIe power. The Jetson Orin NX, for example, has a different power management system, and the solution for enabling PCIe power might be different.
To summarize:
- Verify the DTB file modifications
- Check the kernel version and adjust the DTB file accordingly
- Revert to the original DTB file
- Try entering recovery mode using the
Force Recoverybutton - Use a serial console to monitor the boot process
- Seek help from the NVIDIA Developer Forums
By following these steps, you should be able to troubleshoot and potentially resolve the issue with your Jetson AGX Orin Developer’s Kit 64GB.
It is not possible that a board is not able to enter recovery mode just because you did anything to the software.
It could just be that your method to enter recovery mode is never correct.
Please use the button on the carrier board to enter recovery mode.
Sorry, I found I press the wrong button. After entering the recovery mode, I use the flash.sh to flash the old dtb folder to the device, but the error reporting and message as follows. Can you tell me how can I resolve it?

Hello Wayne, thanks for your response. After trying the method in AGX orin 64GB flash fail - Jetson & Embedded Systems / Jetson AGX Orin - NVIDIA Developer Forums, I found that my p3701.conf.common file included the content. And I added “update_local_cfgfile ${localcfgfile}” in flash.sh. And then, I flash again. My device is not rebooted also, the monitor is also black, and the flash message as below.

flash.txt is the content of flash.sh, flash_msg.txt is the content of flash output.

I have no idea why you are trying that sd no one ever asked you to do that. What you did has nothing to do with previous response either.
Please restore everything back to default and flash and share log. Do not modify anything in flash.sh.
Your flash command seems to be wrong too. I really don’t know what you are doing here. Please share how you flash the board too.
Thanks Wayne, I will try it again several days later. Now my teacher gives me an emergency task.
Hello Wayne. I forgot my operations before. In that case, I used sdkmanager to reinstall the system. The system version is R36.4.4 and the jetpack version is 6.1. The pcie pins don’t have 12V also. What should I do next? I’d appreaciate it if you could give me an exact procedure. Thanks again
