Ok, stumped now.  I created a /etc/fw_env.config file with:
/dev/mmcblk1            0x400000        0x1000

Also tried:
/dev/mmcblk1 0x0 0x1000

... mmcblk1 is the sdcard I'm booting.

Now I'm getting:

root@imx8mmevk:/etc# fw_printenv
Cannot read environment, using default
Cannot read default environment from file

This is first time I'm using sdcards or eMMC to store u-boot env, always
did it in NOR before so I'm kinda lost at the moment.

Anyone know where the u-boot env is on sdcard (or eMMC)?

Regards,

Brian
