recipe for target 'prepare3' failed error coming while compiling u-boot using yocto

[mallibeerala]

Hi,

I am trying to compile u-boot(I.MX8QM) from yocto, but while compiling I am getting following error "recipe for target 'prepare3' failed".

Procedure I am using

MACHINE=imx8qmmek bitbake -c clean u-boot-imx -f

MACHINE=imx8qmmek bitbake -c devshell u-boot-imx then window navigated to

                  ~/imx-yocto-bsp-1/build-xwayland-imx8qm/tmp/work/imx8qmmek-poky-linux/u-boot-imx/2018.03-r0/git -> make mrproper

                  ~/imx-yocto-bsp-1/build-xwayland-imx8qm/tmp/work/imx8qmmek-poky-linux/u-boot-imx/2018.03-r0/git -> make imx8qm_mek_defconfig

MACHINE=imx8qmmek bitbake -c fetch u-boot-imx

MACHINE=imx8qmmek bitbake -c compile u-boot-imx

But it is working fine with sandbox architecture.

Please find the attached log file, local.conf, setup environment files

Please help us to resolve this Issue.

Mallikarjuna B,
Thanks & Regards.

Does this error happened after you changed the uboot config/source?

[mallibeerala]

Yes, after changing configuration error is coming.

You need use devtool modify u-boot to generate a workspace source code and then change this source code.
