LLDPUG yocto implementation problem

[jackho]

Hi,

We are now implementation with LLPDUG 5.15.71 on LX2160ARDB_REV2

Some questions below want to check with you. 

1. About meta-layer, I saw meta-qoriq, meta-freescale and meta-nxp-desktop, I am a little confused about  what is different between these layers, which layer is specific for lx2160ardb platform?

2. About u-boot bb files, I saw the below path both have u-boot bb files, how do I confirm which one I am using for lx2160ardb_rev2?

./meta-freescale/recipes-bsp/u-boot/u-boot-qoriq_2021.04.bb

./meta-qoriq/recipes-bsp/u-boot/u-boot-qoriq_2022.04.bb

3. I am trying to modify rcw for our hardware customization and using devtool to generate patch, but it seems the patch does not apply, I saw original rcw_git.bb is in meta-freescale, but meta-qoriq also has rcw_git.bbappend file and I put the patch on meta-qoriq/recipes-bsp/rcw, but the patch didn't apply,  

Thanks.

BR,

Jack Ho

1.The layer meta-qoriq contains the latest Yocto SDK changes of Layerscape;

• And these changes will upstream from meta-qoriq to meta-freescale after NXP BSP releases.
• NXP does not own the layer meta-freescale, which is belong to Yocto community. It contains some customization of other contributors using our SoCs.

meta-nxp-desktop contains recipes for Ubuntu filesystem.

meta-qoriq+meta-freescale is specific for lx2160ardb platform.

2. You should use meta-qoriq/recipes-bsp/u-boot/u-boot-qoriq_2022.04.bb

3. Please try this method.

$ source build_lx2160ardb-rev2/SOURCE_THIS

$ bitbake rcw -c patch -f

Please go to rcw source folder tmp/work/lx2160ardb_rev2-fsl-linux/rcw/git-r0/git/ and apply your patch and do some modifications.

$ patch -p1 <your_patch>

Rebuild rcw with the following command.

$ bitbake rcw -c compile -f

$ bitbake rcw
