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

| Build |
| ===== |
| |
| First, configure Buildroot for your SABRE board. |
| For i.MX6Q SABRE SD board: |
| |
| make freescale_imx6qsabresd_defconfig |
| |
| For i.MX6DL SABRE SD board: |
| |
| make freescale_imx6dlsabresd_defconfig |
| |
| For i.MX6Q SABRE Auto board: |
| |
| make freescale_imx6qsabreauto_defconfig |
| |
| For i.MX6DL SABRE Auto board: |
| |
| make freescale_imx6dlsabreauto_defconfig |
| |
| Build all components: |
| |
| make |
| |
| You will find in ./output/images/ the following files: |
| - imx6dl-sabresd.dtb or imx6q-sabresd.dtb or imx6q-sabreauto.dtb or |
| imx6dl-sabreauto.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/create-boot-sd.sh <your-sd-device> |
| |
| Boot the SABRE board |
| ==================== |
| |
| SABRE SD |
| -------- |
| |
| To boot your newly created system on a SABRE SD Board (refer to the SABRE SD |
| 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. |
| |
| SABRE Auto |
| ---------- |
| |
| To boot your newly created system on a SABRE Auto Board (refer to the SABRE for |
| Automotive Infotainment Quick Start Guide for guidance): |
| - insert the SD card in the CPU card SD card socket J14; |
| - Set the S1, S2 and S3 DIP switches and J3 jumper to boot from SD on CPU card. |
| Reference configuration: |
| |
| S1 |
| 1 2 3 4 5 6 7 8 9 10 |
| off ON off off ON off off off off off |
| |
| S2 |
| 1 2 3 4 |
| off off ON off |
| |
| S3 |
| 1 2 3 4 |
| off off ON ON |
| |
| J3: 1-2 |
| |
| - connect an RS-232 UART cable to CPU card debug port J18 UART DB9 and |
| connect using a terminal emulator at 115200 bps, 8n1; |
| - power on the board. |
| |
| Enjoy! |
