zeus branch doesn't boot on eMMC

[arunlee77]

It looks like the zeus branch is broken w.r.t eMMC boot support.

Steps:

1. Follow the Quick start guide and setup the sources and build area
2. make the following modifications to the conf/local.conf file
   UBOOT_CONFIG = "emmc"
   UBOOT_CONFIG[emmc] = "mx8mq_phanbell_defconfig,sdcard"

The build is success.

Flashing:

1. Interrupt u-boot (boot from sd-card) and enter ums 0 mmc 0
2. dd the .wic.gz image to the enumerated disk
3. Ctrl+C at uboot prompt and enter fastboot 0
4. fastboot flash bootloader0 imx-boot
5. change the dip switches to boot from MMC

Additional Info:
The above procedure works well for warrior branch.

Hi @arunlee77, have you solved the issue?
Because I am facing the same issue.

I am flashing coral board using the SD card flashing method. I am getting following errors:

Has anyone faced the same problem? Help me

Never faced any issue with SD card image. My issues was with eMMC image. We decided to drop coral from our HW list due to issues with SW support.
