客户要求系统在10s内启动，并且能够通过网络向外发送图像数据。
我们现在测试soc从上电到启动时间整体大概50s左右；启动MB1+MB2+UEFI时间大概14秒，kernel大概15秒；剩余为用户空间加载时间。这个时间和客户要求差距很大；仅加载到UEFI的时间就远超预期，太长了。
我们使用的是jetpack5.1.3 。
有针对的启动时间优化方案能够满足客户需求吗？
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!
并不是刷写问题，是针对启动时间优化。
Hi 525554536,
Are you using the devkit or custom board for AGX Orin?
For the boot time optimization, please refer to Boot Time Optimization — NVIDIA Jetson Linux Developer Guide 1 documentation for details.
I think 10s is hard to be achieved on Jetson device, but we’ve verified it could achieve 16s after performing all methods in above instruction.
能提供基于开发套件的，优化启动时间后的镜像让我们测试参考一下吗？
Sorry that we don’t provide the local BSP package on forum directly.
Please just refer to each steps on that instruction and let us know if you have any issues.
其他平台可以实现上述启动时间要求吗？nano系列或者drive系列或者其他？
The link I shared is for JP5.1.4(R35.6.0).
It should work for the platforms with this release.
e.g. Orin Nano supports this release so that it is applicable.
Jetson Nano does not support this release and there’s no UEFI as bootloader so that it is not applicable.
