Hi communicators.

I knew how can porting the OS from i.mx8 board. (as SD Card)

(As you may already know, sdcard is mmc. and emmc is embeded mmc.)

I recently completed to porting Android OS through SD card(mmc).

so I want to booting of OS through eMMC (Not MMC)

so I show you my step by step screenshot:

1. setting the boot switch

2. power switch ON

3. UUU.exe execute:

(I want to port to Android10 OS so I download and uuu execute)

    1. CMD input : .\uuu_imx_android_flash.bat -f imx8mm -a -e -t 1

    2. MMC: FSL_SDHC: 1
        Loading Environment from MMC... Card did not respond to voltage select!
        *** Warning - No block device, using default environment

   3. ucmd mmc dev 1

   4. MMC card init failed!
       Card did not respond to voltage select!
       ** Block device MMC 1 not supported
