Quick boot with Yocto

[hjpark71]

Hi Guys,,

I'm developing an application on I.MAX6UL and I.MAX6 with Yocto(fsl-image-qt5) but the booting speed is quite slow as it takes more than 10secs booting from NAND and SDCard.

I would like to reduce the booting time to 2 or 3 seconds with QT5..

Do you already support quick boot on Yocto ? if yes, please let me know how to get it and run..

if not, pls let me khow how to support quick boot on Yocto..

thanks a lot..

Hi Hj Park,

                  In order to obtain faster boot times, you need to customize the rootfs to remove services which you do not require. You can also modify the kernel to disable prints during boot (if you donot require them) to achieve faster boot time. Additionally, you can remove unwanted kernel drivers.

You need to find which stage of the boot process consumes more time. For that you can use applications like bootchart.
