iMX8MQ-EVK: flashing eMMC problem

[Julie3]

Hi,

After bitbaking my imx-image-core for iMX8MQ-EVK, I tried to find how to flash an eMMC image.

I found some tutorials which use UUU tool:

- 'uuu -v -b emmc_all ' + .sdcard file (rootfs) + .bin-flash_evk file (bootloader)

- 'uuu_flash -b' + board_name + '-i ' .sdcard.bz2 file

The problem is that I don't have .sdcard file or .sdcard.bz2 file. So, I cannot use these methods.

Do you know how I could flash my eMMC image with an other command, or maybe help me to get .sdcard file or .sdcard.bz2 file?

You can see below the files that I have in my deploy/images/imx8mq-evk folder:
