hi nv
https://docs.nvidia.com/jetson/archives/r35.4.1/DeveloperGuide/text/SD/SoftwarePackagesAndTheUpdateMechanism.html?highlight=ota#over-the-air-update
参考贵司的文档做OTA升级验证，Xavier Nx Devkit - eMMC R32.7.2->R35.4.1
在执行最后一个步骤重启后，设备没有进入recovery升级模式，请帮忙看下，谢谢！

Hi yougang.hu,

OTA preprocess has been completed. OTA will be automatically started once device is rebooted

It seems you didn’t run sudo reboot after you finish nv_ota_start.sh.

问题就出在这，重启后并没有进入recovery升级模式，而是正常的进了BASE_BSP系统

Please share the full serial console log after you run reboot command.

我的操作步骤如下
host-PC端:
export BASE_BSP=${HOME}/work/nvidia/nvidia_sdk/JetPack_4.6.2_Linux_JETSON_XAVIER_NX_TARGETS/Linux_for_Tegra
export TARGET_BSP=${HOME}/work/nvidia/nvidia_sdk/JetPack_5.1.2_Linux_JETSON_XAVIER_NX_TARGETS/Linux_for_Tegra
cd ${BASE_BSP}
sudo ./flash.sh jetson-xavier-nx-devkit-emmc mmcblk0p1

cd ${TARGET_BSP}/…/
sudo tar xpf ota_tools_r35.4.1_aarch64.tbz2

cd ${TARGET_BSP}
sudo ./tools/ota_tools/version_upgrade/build_base_recovery_image.sh jetson-xavier-nx-devkit-emmc R32-7 ${BASE_BSP} ${BASE_BSP}/rootfs ${TARGET_BSP}
sudo -E ./tools/ota_tools/version_upgrade/l4t_generate_ota_package.sh jetson-xavier-nx-devkit-emmc R32-7

device端：
sudo tar xpf ota_tools_r35.4.1_aarch64.tbz2
cd Linux_for_Tegra/tools/ota_tools/version_upgrade
sudo ./nv_ota_start.sh /media/sd/ota_payload_package.tar.gz
sudo reboot

PC端是完全按照文档来的，设备端因为存储空间不够的原因，在执行nv_ota_start.sh脚本前，在设备系统上删除了一些应用，ota_payload_package.tar.gz放在外置存储中

如果你要更新eMMC，建議將payload放在eMMC內

你也可以參考以下Xavier NX從R32.7.4升到R35.4.1的步驟以及預期的訊息:
Jetson/L4T/peripheral/ - Image-Based OTA with layout change

在jp4.6.4上，相同的操作，OTA升级成功
有个问题请教下，系统从emmc启动，但是rootfs是挂载在nvme上，做OTA升级后，是否可以将系统刷到nvme上？

12

那會建議你在升級前就先更改為從NVMe啟動並且掛載rootfs在NVMe上
整個建立image-based OTA package的過程也都是針對(指定)NVMe去建立和更新
