Boottime optimization

[naveenprasath_0]

Hi,

We are using custom board using imx6sx processor.The board boot time is around 18 seconds.
u-boot takes 1.5s,kernel takes 2s,and systemd takes 14.5s.

How to reduce this overall bootup time?

Otherwise is there any way to make ethernet interface up and running before board bootup fully?

Hi naveenprasath_0,

You can use the falcon mode to reduce the boot time

For your second question, the short answer is yes, but you need to recompile the kernel and make some changes, this can give you a clue of what are you looking:
