請問如何加快AM335X SDK6.0 開機時間???

Expert 2272 points
Other Parts Discussed in Thread: TPS65910

我們的板子,開機log如下

從上電到login約需15sec

我們的功能僅用到gpmc for FPGA,1組ethernet,1組usb,其他都gpio

1.請問該如何加快開機時間呢??

2.我知道使用ramdisk 會拖慢開機時間,因生產問題,這沒辦法修改 

3.我使用arago-base-tisdk-image-am335x-evm來做rootfs,並製作成ramdisk

    lib與/usr/lib 哪些東西可以移去??

4.為什麼 Starting udev要花費將近3秒的時間呢??
