How to reduce boot time on iMX6UL-evk ?

[toanjunifer]

Hi everyone,

My name is Toan. Currently, I'm using iMX6UL-evk with kernel rev L4.14.98_2.0.0_ga. The boot time is approximate 30 seconds. And I wanna reduce this time to under 10 seconds (from start to show up login )

I tried to set boot delay to 0 sec. It's working.

And I tried follow: Linux Fast Boot on i.MX6 Sabresd Board but I dont know what exactly I need to do. I quite vague about this.

So, how can I do now ? May you share me a little experience or trick ?

Thank you very much,

Toan

Hello Dao,

You can reduce the boot time using the fast boot to 4 secs. Just Remove unnecessary modules at boot time.

Hi Bio_TICFSL‌,

Thank you for your reply. May you guide me how to remove unnecessary module at boot time ? Just give me an example, it's okay ^^. 

I tried to remove some in menuconfig but It's not working. 

Anyway, I very glad when you reply me. 

Best regards,

Toan
