Re: X3开发板,启动到命令行5s左右,有没有办法让他启动速度更快??

我也尝试改动DRAM、CPU时钟、以及将一些驱动都变成模块,减少镜像的大小,发现启动时间变化的不是很明显,还是要4S多,想要加快启动,不外乎这些方法,实在不知道怎样才能比较明显的缩短启动时间了

Re: X3开发板,启动到命令行5s左右,有没有办法让他启动速度更快??

你的linux启动不到2秒,说明其他占了3秒。

1. 剪裁uboot,屏蔽不必要的驱动,比如spi/usb/net那些用不到的可以全部干掉

2. linux那些驱动可以编译成ko,一方面瘦身zImage,另一方面可以延迟加载驱动。

Re: X3开发板,启动到命令行5s左右,有没有办法让他启动速度更快??

哇酷小二 说:

你的linux启动不到2秒,说明其他占了3秒。

1. 剪裁uboot,屏蔽不必要的驱动,比如spi/usb/net那些用不到的可以全部干掉

2. linux那些驱动可以编译成ko,一方面瘦身zImage,另一方面可以延迟加载驱动。

请问一下,有一些配置不能够取消,这种情况应该是前面有配置限定了,但是怎样知道是哪个配置限制了,百度不到,尴尬!

根据取消不了的关键字,grep搜索整个目录,需要修改Kconfig文件。
