您好：
我们现在使用一款jetson nano 板卡pn :945-13541-0001-000，使用的jetpack4.6.6,r32.7.6,我们想优化下启动时间，目前测试从上电到系统启动进字符界面，总启动时间16s：其中uboot之前部分启动时间6s，uboot启动时间2s，内核启动时间1.8s，应用启动时间6s。我们想问下启动时间还有优化空间么？总的启动时间可以优化到5秒么？有的话，麻烦提供下优化方法，谢谢了。

Hello,

Thanks for visiting the NVIDIA Developer forums! Your topic will be best served in the Jetson category.

Hi 412574090,

Are you using the devkit or custom board for Jetson Nano?

Please share the result of the following command on your board.

$ cat /etc/nv_boot_control.conf

And also, the full serial console log with timestamp enabled.

Have you referred to Kernel Boot Time Optimization for the method to optimize the boo time?

Hi KevinFFF,
kernel version is 4.19.337 with r32.7.6, Kernel Boot Time Optimization,we have tried, now boot time have reduced to 16s. could boot time can reduce to 10s?

Thanks a lot
