- =====
- First, configure Buildroot for the i.MX7D Pico board:
- make imx7dpico_defconfig
- Build all components:

- 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.
