| This file documents the Buildroot support for the Freescale SABRE Board for |
| Smart Devices Based on the i.MX 6 Series (SABRESD). |
| |
| Read the SABRESD Quick Start Guide for an introduction to the board: |

| |
| Build |
| ===== |
| |
| First, configure Buildroot for your SABRESD board. |
| For i.MX6Q: |
| |
| make freescale_imx6qsabresd_defconfig |
| |
| For i.MX6DL: |
| |
| make freescale_imx6dlsabresd_defconfig |
| |
| Build all components: |
| |
| make |
| |
| You will find in ./output/images/ the following files: |
| - imx6dl-sabresd.dtb or imx6q-sabresd.dtb |
| - rootfs.ext2 |
| - rootfs.tar |
| - u-boot.imx |
| - uImage |
| |
| 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 |
| |
| Run the following script as root on your SD card. This will partition the card |
| and copy the bootloader, kernel, DTBs and root filesystem as needed. |
| |
| *** WARNING! The script will destroy all the card content. Use with care! *** |
| |
| ./board/freescale/imx6sabresd/create-boot-sd.sh <your-sd-device> |
| |
| Boot the SABRESD board |
| ====================== |
| |
| To boot your newly created system (refer to the SABRESD Quick Start Guide for |
| guidance): |
| - insert the SD card in the SD3 slot of the board; |
| - locate the BOOT dip switches (SW6), set dips 2 and 7 to ON, all others to OFF; |
| - connect a Micro USB cable to Debug Port and connect using a terminal emulator |
| at 115200 bps, 8n1; |
| - power on the board. |
| |
| Enjoy! |
