I have built the http://freescale.github.io 
<http://freescale.github.io/> Yocto core-image-sato build for a 
Wandboard WB-IMX6U-BW under Fedora33 (Python3) fine and it runs on the 
board.

I used "repo init -u 
https://github.com/Freescale/fsl-community-bsp-platform".

However when adding: IMAGE_INSTALL_append = " gstreamer1.0-plugins-imx" 
to my local.conf I get the build error:

ERROR: Nothing RPROVIDES 'gstreamer1.0-plugins-imx' (but 
/datal3/DartSystems/ds200i-system/fsl-community-bsp/sources/poky/meta/recipes-sato/images/core-image-sato.bb 
RDEPENDS on or otherwise requires it)
gstreamer1.0-plugins-imx was skipped: incompatible with machine 
wandboard (not in COMPATIBLE_MACHINE)
NOTE: Runtime target 'gstreamer1.0-plugins-imx' is unbuildable, removing...
Missing or unbuildable dependency chain was: ['gstreamer1.0-plugins-imx']

The sources/meta-freescale-3rdparty/conf/machine/wandboard.conf has:

MACHINEOVERRIDES =. "mx6:mx6dl:mx6q:"

and 
sources/meta-freescale/recipes-multimedia/gstreamer/gstreamer1.0-plugins-imx_0.13.1.bb 
has:

COMPATIBLE_MACHINE = "(mx6dl|mx6q|mx6sl|mx6sx|mx6ul|mx6ull|mx7d)"

Any ideas on why this is happening ?
