Vim3 server版启动速度优化方法

VIM3
1

启动接近40秒，太慢了，请教一下有没有什么优化方法，能10秒内启动。

fiddle with systemctl

  • set default target multiuser
  • mask networkmanager during boot
    should reduce around 10sec

@eaglet 首先源码是开放的，你可以自行修改。你可以删减一些你觉得不需要的驱动。但是你要求在10S之内，ubuntu系统是不大可能做到的。你可以试一下buildroot

谢谢回复。我也有在尝试删减驱动，但发现uboot启动就要5s

Starting kernel ...

uboot time: 5174541 us #这里显示5秒

还有好多处卡着很久，不知道应该怎么改动，如此处卡4秒

此处卡5秒

Jan 12 06:25:50 localhost kernel: [   35.160148@0] fb: osd_release now.index=3,open_count=1

没办法的话，我后面尝试研究一下buildroot。

请问一下，这个buildroot编译出来的固件如何烧到板子上？

@eaglet output/mesong12b_xxx_release/images/aml_upgrade_package.img这个就是你编译出来的buildroot镜像。同样适用我们usb烧录工具，参考文档烧录即可。
