First, configure Buildroot for the i.MX8QM MEK board:
$ make freescale_imx8qmmek_defconfig
Build all components:
$ make
You will find in output/images/ the following files:
- ahab-container.img
- bl31.bin
- boot.vfat
- fsl-imx8qm-mek.dtb

Create a bootable SD card
=========================
To determine the device associated to the SD card have a look in the
/proc/partitions file:
cat /proc/partitions
Buildroot prepares a bootable "sdcard.img" image in the output/images/
directory, ready to be dumped on a SD card. Launch the following
command as root:
dd if=output/images/sdcard.img of=/dev/<your-sd-device>
*** WARNING! This will destroy all the card content. Use with care! ***
For details about the medium image layout, see the definition in
board/freescale/common/imx/genimage.cfg.template_imx8.
Boot the i.MX8QM MEK board
==========================
To boot your newly created system:
- insert the SD card in the SD slot of the board;
- Configure the boot switch as follows:
SW2: OFF OFF ON ON OFF OFF
- put a micro USB cable into the Debug USB Port and connect using a terminal
emulator at 115200 bps, 8n1;
- power on the board.
Enjoy!
