imx8m mini custom board will load uboot to RAM and execute via "uuu -b spl imx-boot", but the command that came with the latest mfgtools git repo command "uuu -b emmc imx-boot" says success... however... the unit will not boot.
So it appears the nothing is burned, and I don't see where anything is erased...

But the uboot sequence works:
pcip=10.212.238.187;dhcp $loadaddr $pcip:imx-boot
mmc dev 2 && mmc info
mmc erase 42 1000
mmc write $loadaddr 42 $filesize
Any ideas?
uboot version: U-Boot 2019.04

Thanks for any info.
