Hi,

 

The default Linux kernel is built by using bitbake fsl-image-networking. Here, the kernel is built from meta-freescale/recipes-kernel/linux/linux-qoriq_5.4.bb path and source code is fetching from "git://source.codeaurora.org/external/qoriq/qoriq-components/linux;nobranch=1".

 

So I want to use another version of the kernel that should be fetch from "https://source.codeaurora.org/quic/femto5G/fsm/external/qoriq-components/linux_4.19-rt/" and the SRC_REV= "74700acb31e369495da22b4bbfd9e3f4315fc74a"

When you want to use another version of the kernel it is better to create new recipe (.bb file). You
could use existing linux-qoriq_5.10 [1] recipe as example, just change the SRC_URI, SRCREV and
LINUX_VERSION.

Than in distro or machine config you would need to set PREFERRED_VERSION_linux-qoriq to 4.19
or whatever the version is.

 

 

For that purpose, I have created a .bbappend file and changed the SRC_URI as well as SRC_REV.

While building bitbake is causing errors,

Can you please help me to resolve the issues?

Thank you
