hi jimmychan​ after going through the error which I got ERROR: Task 71 (/home/plum_project/sources/meta-fsl-arm/recipes-kernel/linux/linux-imx_3.14.28.bb, do_install) failed with exit code '1' after bitbaking core-image-minimal it is actually bitbaking the 3.14.28 kernel version and it didnt have support for imx6ulevk.

So, after going through all the bb files i thought of using poky-tiny distro, sources/poky/meta-yocto/conf/distro/poky-tiny.bb

I changed some of the configuration

PREFERRED_PROVIDER_virtual/kernel = "linux-imx"

PREFERRED_VERSION_linux-imx = "3.14.38"

after that I ran bitbake core-image-minimal it is successful and generated the images.

One last check point is, it didnt generate sdcard images instead it genertaed core-image-minimal-imx6ulevk-20160708092743.rootfs.cpio.gz

These steps maybe useful for the people who use 3.14.38 for imx6ulevk for core-image-minimal

[jimmychan]

please try to create a new build folder for the new build.

DISTRO=<distro name> MACHINE=<machine name> source fsl-setup-release.sh -b <build dir>

Hi jimmychan​ i tried bitbake core-image-minimal

but i got below error

DEPMOD  3.14.28-1.0.0_ga+g91cf351

I am using the below repo

repo init -u git://git.freescale.com/imx/fsl-arm-yocto-bsp.git -b imx-3.14.38-6UL_ga

[jimmychan]

your rootfs need 868MB

[chandraevolute]

jimmychan  how can i reduce the rootfs size......my zImage is nly 6MB...for my project we planned to use nly 256 MB size of sdcard

[jimmychan]

It depends what you build and install in the rootfs. you can try to build the core-image-minimal. You will get the small size of rootfs.
