LSDK migration on Yocto project

rrbhaskara — Wed, 06 Apr 2022 05:54:34 GMT

We are building firmware for layerscape LX2160ARDB platform. Since we have done the changes on LSDK 21.08 sources, we would like to build the same firmware with the LSDK changes using yocto project. Can anyone please suggest how can we migrate lsdk changes into yocto project to build the firmware?

Thank you

You could download the latest Yocto hardknott Linux SDK from the following link.

https://source.codeaurora.org/external/qoriq/qoriq-components/yocto-sdk/tree/readme?h=hardknott

$ source ./setup-env -m lx2160ardb

$ bitbake u-boot -c cleansstate

$ bitbake u-boot -c patch

Go to u-boot source code folder build_lx2160ardb/tmp/work/lx2160ardb-fsl-linux/u-boot-qoriq/2021.04+AUTOINC+263b27e076+fslgit-r0/git/, apply patches for u-boot.

$ bitbake u-boot

$ bitbake qoriq-atf -c cleansstate

$ bitbake qoriq-atf -c patch

Go to atf source code folder build_lx2160ardb/tmp/work/lx2160ardb-fsl-linux/qoriq-atf/2.4+AUTOINC+atf-r0/git/, apply patches for atf.

$ bitbake qoriq-atf

Generate atf images in folder build_lx2160ardb/tmp/deploy/images/ls1046afrwy/atf/.

Thank you @yipingwang,

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"

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,
