Hi,

Could you please help me with clear step by step procedure to minimize the boot up time.

The information in the link https://community.nxp.com/docs/DOC-93619 is not very clear for me.

Hi Rita,

I am using sabre imx6 board.

I am trying to reduce the bootup time by removing unwanted driver init from kernel.

I have fallowed the below steps to build.

$ repo init -u git://git.freescale.com/imx/fsl-arm-yocto-bsp.git -b imx-4.1.15-1.0.0_ga

$ DISTRO=fsl-imx-wayland MACHINE=imx6qsabreauto source fsl-setup-release.sh –b build-wayland

$ Bitbake fsl-image-qt5

we are using .sdcard image.

$ bitbake linux-imx -c cleansstate

$ bitbake linux-imx -c cleansall

$ bitbake linux-imx -c menuconfig

change the configuration save and exit.

copy the .config to defconfig.

$ cp build/tmp/work/imx6qsabresd-poky-linux-gnueabi/linux-imx/4.1.15-r0/build/.config

/sources/meta-fsl-arm/recipes-kernel/linux/linux-imx-3.14.38/imx/defconfig

$ bitbake linux-imx -c cleansstate

$ bitbake linux-imx -c cleansall

$ bitbake fsl-image-qt5

But I dont see any changes in the kernel initialization.

Please let me know proper methods to implement this.

Thanks,

Rajath
