How to reduce the boot time to the minimum amount ls1021a-twr

[jiye]

Hi,

I have a ls1021a-twr eva board.  My linux kernel version is 4.19. I used lsdk1906 

flex-builder -i mkrfs -r debian:lite:stretch   

to generate the minimum size of the rootfs around 450 MB.

I also reduced the amount of modules from 460 to 98 in the system. 

I still feel it takes quite large amount of time to boot the system. I wonder if any way knows a good way to decrease the amount of boost time.

Hello Elias Bitbaker ,

Please use fast boot, please add parameter "quiet lpj=250000" in bootargs.

Thanks,

Hi Yiping,

This is my bootargs looks like:

bootargs=root=/dev/ram0 rw console=ttyS0,115200 quiet lpj=250000

seems there is no difference in terms of boot speed.

The bootargs "quiet lpj=250000" is used to reduce the serial printing information, so it will reduce the boot time.

Thanks,

Yiping

is this correct ?

bootargs=root=/dev/ram0 rw console=ttyS0,115200 quiet lpj=250000

It's correct.
