We are creating a BSP for our i.MX 8X (i.MX 8QuadXPlus) based product.
To start, we are trying to build an existing BSP as a point of reference.
Have followed the instructions here:
https://github.com/Freescale/fsl-community-bsp-platform
But am getting:
| make[1]: *** No rule to make target 'arch/arm64/boot/dts/freescale/imx8qxp-mek-dom0.dtb'.  Stop.
| make: *** [/workdir/fsl-community-bsp/build/tmp/work-shared/imx8qxp-mek/kernel-source/Makefile:1425: freescale/imx8qxp-mek-dom0.dtb] Error 2

i.e.
repo init -u https://github.com/Freescale/fsl-community-bsp-platform -b kirkstone
repo sync
MACHINE=imx8qxp-mek DISTRO=fslc-wayland source setup-environment build
bitbake core-image-minimal

bitbake -e | grep PREFERRED_PROVIDER_virtual/kernel
gives
PREFERRED_PROVIDER_virtual/kernel="linux-fslc-imx"

changing local.conf to
PREFERRED_PROVIDER_virtual/kernel="linux-imx"
(and deleting tmp) produces the same error

Am I doing something wrong, or is this a bug?
Which combination of MACHINE, DISTRO, image, provider is a known working starting point for i.MX 8X (i.MX 8QuadXPlus) please?
