I don't think so.  The core-image-minimal image I built with poky as distro 
boots clean when I replace the kernel with the one where I went into make 
menuconfig and turned off PCI and some other things.  I think systemd just 
isn't happy with the core-image-base built with fslc-wayland distro as I have a 
plain, bare imx8mmevk ... normally that have video card, touch screen and other 
stuff hooked up to them ... so none of that stuff is started properly.

Well, when I changed the .config I just did bitbake -c clean virtual/kernel, 
bitbake -c menuconfig virtual/kernel, bitbake virtual/kernel then copy Image to 
FAT of SD Card.

See mmcblk1 p1 & p2 are seen this time ... and mounted ... otherwise systemd

Thanks for pointing that out, but I didn't do anything out of the ordinary so 
there must be an issue in the local.conf or a recipe somewhere.

Here is exactly what I did:

I made a directory for Freescale Community BSP for Poky core-image-minimal and 
another directory for core-image-base fslc-wayland build.

In both directories I followed instructions on the Freescale Community BSP web 
site:

repo init -u https://github.com/Freescale/fsl-community-bsp-platform -b dunfell
repo sync

In one directory I ran:

MACHINE=imx8mmevk DISTRO=fslc-wayland source setup-environment build

In the other I ran:

MACHINE=imx8mmevk DISTRO=poky source setup-environment build

For fslc-wayland distro I then ran bitbake core-image-base without changing a 
thing in bblayers.conf or local.conf

For poky distro I ran bitbake core-image-minimal without changing a thing in 
bblayers.conf or local.conf

I then used the same SD Card and flashed both resulting images and tried them 
and both hung in same spot.

I suspected device tree or kernel config issues so I rebuilt kernel and 
replaced the Image in FAT partition.  That's the only change I made, then board 
booted the core-image-base image and systemd went into emergency mode (the logs 
I posted).

I then used same SD Card and dd core-image-minimal image and again replaced the 
Image in FAT partition with kernel I did menuconfig on to turn off PCI, wifi, 
graphics etc. and it booted up super clean with no issues at all (Sys V init, 
now systemd).  Again, all I changed in both cases was the kernel.

So if I'm not getting the right kernel, maybe I need a Preferred provider in my 
local.conf (but shouldn't that be there to start with if that's the case?).  
All I did was follow the web site instructions then set off building and 
flashing and testing.

Don't know what that's about but /dev/mmcblk1p2 is mounted or systemd would not 
be running right now!  And what is /dev/mmcblkp1 supposed to be anyway?  Looks 
like typeo to me.  Should be referring to /dev/mmcblk1p1 or /dev/mmcblk1p2
