  1. Technologic Systems TS-7680 SBC
  2. ===============================
  3. This document explains how to set up a basic Buildroot system for
  4. the Technologic Systems TS-7680 Single Board Computer.
  5. The TS-7680 SBC is based on the Freescale i.MX286 ARM ARM926EJ-S
  6. running at 454MHz. The TS-7680 features are 10/100 Ethernet ports,
  7. Wi-Fi, microSD card, eMMC, NOR Flash, USB host port, CAN ports,
  8. relays and ADC/DAC. More details on the board here:
  9. https://wiki.embeddedarm.com/wiki/TS-7680
  10. The TS-7680 uses a 4.9 Linux kernel provided by Technologic Systems.
  11. To build the default configuration you only have to run:
  12. $ make ts7680_defconfig
  13. $ make
  14. The output looks like:
  15. output/images
  16. ├── imx28-ts7680.dtb
  17. ├── rootfs.ext2
  18. ├── rootfs.ext4 -> rootfs.ext2
  19. ├── rootfs.tar
  20. ├── sdcard.img
  21. └── uImage
  22. The provided genimage configuration generates an image file containing
  23. two partitions. The first one is unused, but mandatory as the
  24. TS-7680 built-in bootloader loads the Linux uImage from the /boot
  25. directory in the second partition. The second partition contains the
  26. rootfs with the Linux uImage into the /boot directory.
  27. $ fdisk output/images/sdcard.img
  28. output/images/sdcard.img1 1 1 1 512B 0 Empty
  29. output/images/sdcard.img2 2 524289 524288 256M 83 Linux
  30. This image can be directly written to an SD card.
  31. $ sudo dd if=output/images/sdcard.img of=/dev/mmcblk0
  32. To boot with Buildroot, insert this SD card on the board, make sure
  33. the SD jumper is present and the U-Boot jumper is not.
  34. The bootloader comes pre-flashed on the board on an SPI flash. Since
  35. updating the bootloader is risky and not trivial, it is not included
  36. in the Buildroot defconfig. Refer to
  37. https://wiki.embeddedarm.com/wiki/TS-7680#U-Boot for details on
  38. which U-Boot config to use and how to flash it.
