Hi Drew,
Thanks a lot for looking into this, its really appreciated 
So on my side, I am trying to integrate Mender on:
1-Apalis-iMX8QM running Boot2Qt based on Zeus (uboot-toradex_2018.3) on Apalis Evaluation Board V1.1C
2-Colibri iMX6ULL running Boot2Qt based on Zeus (uboot-toradex_ 2019.7) on Colibri Evaluation Board V3.2B
For the Aplis-iMX8, I have the image compiled and it no longer complained about mender-grow-data.service but I still have two issues:
1- When I run mender daemon, I get this error:
ERRO[0000] Failed to read the current active partition: No match between boot and root partitions.: Failed mender_saveenv_canary check. There is an error in the U-Boot setup. Likely causes are: 1) Mismatch between the U-Boot boot loader environment location and the location specified in /etc/fw_env.config. 2) ‘mender_setup’ is not run by the U-Boot boot script: exit status 1
The reason could be either that fw_env.config is set with the correct Device name , Device offset , and Env. size so that they match those U-Boot is using or (what is think is the case) that mender_setup’ is not run by the U-Boot boot script.
2- The 2nd issue is that after the board finishes booting, I get this message repeatedly:
mmcblk1: response CRC error sending SET_BLOCK_COUNT command, card status 0xc00b00
To get to this point, I made modifications to the mender-community patches:

With this conf file and patches I have the following observations:
1- if I set:
MENDER_BOOT_PART_SIZE_MB=“0”
I get 3 partitions inseated of 4 (no boot partition), but the board doesnt boot. During compiling, i get this warning message:
WARNING: b2qt-embedded-qt5-image-1.0-r0 do_image_sdimg: MENDER_BOOT_PART_SIZE_MB is set to zero, but IMAGE_BOOT_FILES is not empty. The files are being omitted from the image.
Which is strange because IMAGE_BOOT_FILES is empty in local.conf. Any ideas where else it is getting set ?
2- if I print the uboot environemnt variables, I dont find any Mender variables even though those variables exist in the env.txt file produced by compiling u-boot. Is it possible that the default variables are loaded instead? I believe this is the reason I get the first issue I mentioned above, since mender-setup is not called during booting.
