在Jetson平台JP6版本上，包括Orin NX和AGX Orin开发套件，尝尝会有upgrade更新失败，jtop无法获取到JetPack版本等问题，给出具体原因和解决方法。

问题：

在 Jetson JP6.X 版本中，如果是客户自定义的板子，执行sudo apt upgrade时常会遇到失败的情况，nvidia-l4t-kernel、nvidia-l4t-kernel-headers、 nvidia-l4t-kernel-dtbs等无法更新的情况。​​​​​​，如下图：

dpkg: error processing package nvidia-l4t-kernel-dtbs (--configure): dependency problems - leaving unconfigured Errors were encountered while processing: nvidia-l4t-kernel nvidia-l4t-kernel-headers nvidia-l4t-jetson-io nvidia-l4t-display-kernel nvidia-l4t-kernel-dtbs E: Sub-process /usr/bin/dpkg returned an error code (1)

原因

问题原因是：客户自定义的板子，nvidia-l4t-display-kerne等特定资源并不需要更新，这些资源仅在jetson开发板场景下才需要进行更新。因此，通过apt-mark hold命令锁定这些包，以此跳过相关更新操作。

解决步骤如下：

1. 如果是客户自定板子需要执行，开发板跳过此步

JP6.2： sudo apt-mark hold nvidia-l4t-display-kernel nvidia-l4t-kernel nvidia-l4t-kernel-dtbs nvidia-l4t-kernel-headers nvidia-l4t-kernel-oot-headers nvidia-l4t-kernel-oot-modules nvidia-l4t-initrd JP5.1.5： sudo apt-mark hold nvidia-l4t-bootloader nvidia-l4t-kernel nvidia-l4t-kernel-headers nvidia-l4t-jetson-io nvidia-l4t-display-kernel nvidia-l4t-kernel-dtbs

2. 确认现在BSP version，在文件/etc/nv_tegra_release中

$ cat /etc/nv_tegra_release # R36 (release), REVISION: 4.0, GCID: 37537400, BOARD: generic, EABI: aarch64, DATE: Fri Sep 13 04:36:44 UTC 2024 # KERNEL_VARIANT: oot TARGET_USERSPACE_LIB_DIR=nvidia TARGET_USERSPACE_LIB_DIR_PATH=usr/lib/aarch64-linux-gnu/nvidia

3. 修改 /etc/apt/sources.list.d/nvidia-l4t-apt-source.list

#deb https://repo.download.nvidia.com/jetson/common r36.4 main #deb https://repo.download.nvidia.com/jetson/t234 r36.4 main #deb https://repo.download.nvidia.com/jetson/ffmpeg r36.4 main

4. 更改 apt src，执行 upgrade

sudo apt update sudo apt upgrade

5. 确认系统保持原样

cat /etc/nv_tegra_release # R36 (release), REVISION: 4.0, GCID: 37537400, BOARD: generic, EABI: aarch64, DATE: Fri Sep 13 04:36:44 UTC 2024 # KERNEL_VARIANT: oot TARGET_USERSPACE_LIB_DIR=nvidia TARGET_USERSPACE_LIB_DIR_PATH=usr/lib/aarch64-linux-gnu/nvidia

6. upgrade 36.4.4 改回 nvidia-l4t-apt-source.list

deb https://repo.download.nvidia.com/jetson/common r36.4 main deb https://repo.download.nvidia.com/jetson/t234 r36.4 main deb https://repo.download.nvidia.com/jetson/ffmpeg r36.4 main

7. 更改 apt src，执行 upgrade

sudo apt update sudo apt upgrade

更新到最后，会遇到如下选项，一定要输入"N"，跳过更新，否则会更新到最新36.4.7；

8. 确认系统upgrade 到 36.4.4

cat /etc/nv_tegra_release # R36 (release), REVISION: 4.4, GCID: 41062509, BOARD: generic, EABI: aarch64, DATE: Mon Jun 16 16:07:13 UTC 2025 # KERNEL_VARIANT: oot TARGET_USERSPACE_LIB_DIR=nvidia TARGET_USERSPACE_LIB_DIR_PATH=usr/lib/aarch64-linux-gnu/nvidia

9. 如果要保留原系统，在更新apt

如果要保留原系统，如果不是，请在修改文件之后/etc/nv_tegra_release 执行

sudo apt update sudo apt upgrade

其中第二部到第九步解决jetson开发板和自定义板子upgrade报错的问题。

Jtop 修复：显示 JetPack 6.2.1 版本

如果遇到上述jp6.2.1无法获取到JetPack版本，是因为/jetson_variables.py缺少jp6.2.1，添加步骤如下：

在文件/usr/local/lib/python3.10/dist-packages/jtop/core/jetson_variables.py第45行增加一行

# -------- JP6 -------- "36.4.4": "6.2.1", ###此行是增加的，否则识别不到jp6.2.1 "36.4.3": "6.2", "36.4.2": "6.1 (rev1)", "36.4.0": "6.1", "36.3.0": "6.0", "36.2.0": "6.0 DP", "36.0.0": "6.0 EA",

重启之后，sudo jtop能正常显示JetPack。如果在jp5.1.5上遇到相似的问题，相同方法修改。

Jtop 修复：AGX ORIN 32G JetPack 6.2 版本无法启动

AGX ORIN 32G JetPack 6.2 版本无法启动，/etc/nvpmodel.conf文件默认配置是64G的，需要修改此文件
