| Build |
| ===== |
| |
| 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 |
| - Image |

| - mkimg.commit |
| - mx8qm-mek-scfw-tcm.bin |
| - mx8qm-val-scfw-tcm.bin |
| - mx8qm-a0-ddr4-scfw-tcm.bin |
| - mx8qm-a0-mek-scfw-tcm.bin |
| - mx8qm-a0-val-scfw-tcm.bin |
| - mx8qm-ddr4-scfw-tcm.bin |

| 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! |
