"bitbake core-image-minimal" for p2041rdb Qoriq board, exits with ERROR: oe_runmake failed

[Sreesyam]

I was trying to upgrade to SDK 2.7 (linux 4.19) for my p2041rdb board

1. Yocto layers were downloaded, build environment was successfully setup.
2. All steps including '. ./setup-env -m p2041rdb' were successfully executed and I proceeded to building image using bitbake command.
3. 'bitbake fsl-image-networking' command when executed returned failure, with following error (bitbake core-image-minimal also returned same error)

In Yocto SDK 2.7, the gcc version is 8.3, GCC related recipes are located in sources/poky/meta/recipes-devtools/gcc/. However, in your log, GCC recipes are in sources/meta-qoriq-demos/recipes-devtools/gcc/, version is 4.9.

Please download Yocto SDK 2.7 following the steps in https://source.codeaurora.org/external/qoriq/qoriq-components/yocto-sdk/tree/readme?h=warrior

Please refer to the following procedure to get the Yocto layers from repo manifest.

  Install the repo utility:
   $: mkdir ~/bin
   $: curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
   $: chmod a+x ~/bin/repo

   Download the Yocto layers:
   $: export PATH=${PATH}:~/bin
   $: mkdir yocto-sdk
   $: cd yocto-sdk
   $: repo init -u https://source.codeaurora.org/external/qoriq/qoriq-components/yocto-sdk -b warrior
   $: repo sync --no-clone-bundle

=> We executed the steps with branch- "warrior" in Ubuntu 18.04, but returned following error

$: repo init -u https://source.codeaurora.org/external/qoriq/qoriq-components/yocto-sdk -b warrior

ERROR: Failed to spawn fakeroot worker to run /release/sources/poky/meta/recipes-kernel/linux-libc-headers/linux-libc-headers_5.0.bb:do_install: [Errno 32] Broken pipe

=> Then we tried with branch- "warrior" Ubuntu 20.04, but got a different error

WARNING: Host distribution "ubuntu-20.04" has not been validated with this version of the build system; you may possibly experience unexpected failures. It is recommended that you use a tested distribution.

ERROR: Task (/yocto-sdk/sources/poky/meta/recipes-devtools/qemu/qemu-native_3.1.0.bb:do_compile) failed with exit code '1'

=> However with Ubuntu 16.04 we could progress further with branch-sumo

I confirmed with Yocto SDK integration team, please use Ubuntu 16.04 to build 

Yocto SDK 2.7(warrior).
