Hello, I’m using r35.6 , also I can’t use sudo apt install for RT kernel installation, I get an error when updating the source:
Err:14 https://repo.download.nvidia.cn/jetson/rt-kernel r35.6 Release
404 Not Found [IP: 122.228.98.76 443]
Reading package lists… Done
What’s the solution, please?
Hi 1641123285,
Are you using the devkit or custom board for AGX Orin?
Please share the exact command you used for us to verify locally.
Have you confirmed that you have the network access for your board.
Yes, I am using the AGX Orin series development kit, with Jetson Linux version r35.6.0. Since I wanted to install the real-time kernel, the documentation mentioned that compiled packages have been provided since version 35.1, so I proceeded with the following steps: First, I added the source to /etc/apt/sources.list.d/nvidia-l4t-apt-source.list:
deb https://repo.download.nvidia.com/jetson/rt-kernel r35.6 main
Then I ran sudo apt update and encountered an error:
Err:14 https://repo.download.nvidia.cn/jetson/rt-kernel r35.6 Release
404 Not Found [IP: 122.228.98.72 443]
Reading package lists... Done
E: The repository 'https://repo.download.nvidia.com/jetson/rt-kernel r35.6 Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
Thank you very much for your reply.
Which document were you referring to perform this?
Have you referred to the steps in To Build the Real-Time Kernel?
Kernel Customization — NVIDIA Jetson Linux Developer Guide 1 documentation, which mentions that starting from version 35.1, Real-Time Kernel support is provided as a Developer-Preview for certain platforms, including the Jetson Xavier AGX. You attempted to install it by combining information from other versions of the documentation but were not successful. Then I tried to compile the kernel myself, but encountered issues when flashing the board. The command I ran was:
sudo ./flash.sh jetson-agx-xavier-devkit mmcblk0p1
After executing the command, you received an error indicating that a file could not be found, as shown in the image below.
The kernel resources can be downloaded from this website: Jetson Linux | NVIDIA Developer
I have downloaded the following resources: Driver Package (BSP), Sample Root Filesystem, Driver Package (BSP) Sources, and Bootlin Toolchain gcc 9.3.
Hi 1641123285,
Do you mean the flash issue happen after you build rt-kernel?
Please share the full flash log as file here for further check.
Have you tried using source_sync.sh to get the source instead?
