Unable to Boot Jetson After Automatic Loading of xdma.ko and Application Startup – Need Help Mounting File System in Recovery Mode to Modify rc.local

[649984604]

Hi, everyone.

Problem Description:
The Jetson system fails to boot, unable to Access System or Input via Serial Port ，and I suspect the issue is related to the automatic loading of xdma.ko and application startup through /etc/rc.local, which is causing the failure. I am trying to mount the Jetson file system in recovery mode, while the Jetson device is connected to a virtual machine via USB, to modify /etc/rc.local and /lib/systemd/system/rc-local.service.

Question:
How can I mount the Jetson file system in recovery mode on the virtual machine to make changes to /etc/rc.local and /lib/systemd/system/rc-local.service? Are there other methods to resolve this issue?

大家好：
jetson设备系统启动失败，进入不了系统，串口也不能输入，估计原因是设置的自启动xdma.ko后，自动加载应用程序，导致失败。请问在恢复模式，usb连接电脑的虚拟机，怎么挂载jeson文件系统里我修改/etc/rc.local和lib/systemed/system/rc-local.service？ 或者还有什么其他方法可以解决？

Hi,
If the device cannot be flashed/booted, please refer to the page to get uart log from the device:
Jetson/General debug - eLinux.org
And get logs of host PC and Jetson device for reference. If you are using custom board, you can compare uart log of developer kit and custom board to get more information.
Also please check FAQs:
Jetson AGX Orin FAQ
If possible, we would suggest follow quick start in developer guide to re-flash the system:
Quick Start — NVIDIA Jetson Linux Developer Guide 1 documentation
And see if the issue still persists on a clean-flashed system.
Thanks!

Hi,

你說的東西都做不到. recovery mode狀況下機器根本就不會印log. 除非你說的不是recovery mode.

另外請你給出完整的log. 不要只是截這樣一段
也請不要拍螢幕 這種照片完全沒有幫助

Hi，
上文中的串口信息和显示信息是在正常模式下的打印，程序没有继续执行进入系统。

正常模式下的串口记录日志如下：
serial_info_normal_mode.txt (72.4 KB)

Recovery 模式下的虚拟机记录：
virtual-machine_recovery-mode.txt (5.8 KB)

所以你現在能先確認xdma.ko是你開不了機的主因嗎?

另外我不太確定你到底貼VM log是要做什麼. Host端沒辦法做任何事情. 除非你重燒 或是用其他界面開機 (USB/NVMe SSD)之後去mount eMMC進行更改.

是的，自动加载的ko程序和应用程序有问题。
VM log，本意想通过虚拟机挂载jetson设备的文件系统，这样就可以改掉自动加载的ko和应用程序。
