SCM IMX6 Quick Start Switching Kernels

aliismail — Wed, 13 Jul 2016 17:45:41 GMT

I am using the SCMIMX6 Quick Start board. I am trying to switch out default 3.14.52 kernel for the 3.14.28_rt kernel. So far I have modified the following:

PREFERRED_PROVIDER_virtual/kernel_mx6 = "linux-imx-rt"

PREFFERED_VERSION_linux-imx_mx6 = "3.14.28"

When I compile the kernel with bitbake linux-imx-rt, I get the following error:

ERROR: Function failed: do_install (log file is located at /home/ali/Documents/fsl-arm-yocto-bsp/build-x11/tmp/work/imx6dqscm_1gb_qwks-poky-linux-gnueabi/linux-imx-rt/3.14.28-r0/temp/log.do_install.23525)

I saw imx6qsabrelite yocto switching kernel, and I am not sure what to modify in my machine conf file (imx6dqscm-1gb-qwks.conf). Is it as simple as removing the offending .dtb from the device tree?

Hi,

L3.14.28-rt has not been tested nor migrated to the SCM platform and therefore the patches may not be applied. That is why the .dtb files for the board are not found and you get the error:

No rule to make target `arch/arm/boot/dts/imx6dqscm-1gb-qwks-rev2-fix-ldo.dtb'. Stop.

The imx6dqscm-1gb-qwks-rev2-fix-ldo.dts might not be found in the kernen source code.

You may need to a bbappend file to add the needed patches to this Linux kernel version. Please refer to the files in the SCM package
