| This file documents the Buildroot support for the Technexion i.MX7D Pico board. |
| |
| Build |
| ===== |
| |
| First, configure Buildroot for the i.MX7D Pico board: |
| |
| make imx7dpico_defconfig |
| |
| Build all components: |
| |
| make |
| |
| You will find in output/images/ the following files: |
| - imx7d-pico.dtb |
| - rootfs.ext4 |
| - rootfs.tar |
| - sdcard.img |
| - u-boot.imx |
| - zImage |
| |
| Flash the eMMC |
| ============== |
| |
| In the U-Boot prompt lauch: |
| |
| => ums 0 mmc 0 |
| |
| This will mount the eMMC content in the host PC as a mass storage device. |
| |
| To determine the device associated to the eMMC 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 the eMMC card. Launch the following |
| command as root: |
| |
| dd if=output/images/sdcard.img of=/dev/<your-sd-device> |
| |
| *** WARNING! This will destroy all the eMMC content. Use with care! *** |
| |
| For details about the medium image layout, see the definition in |
| board/freescale/common/imx/genimage.cfg.template. |
| |
| Boot the i.MX7D Pico board |
| ========================== |
| |
| To boot your newly created system: |
| - 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! |
