  1. Technologic Systems TS-4800
  2. ===========================
  3. This document explains how to set up a basic Buildroot system for the
  4. Technologic Systems TS-4800 System on Module.
  5. The TS-4800 is a TS-SOCKET macrocontroller board based on the Freescale
  6. i.MX515 ARM Cortex-A8 CPU running at 800MHz. The TS-4800 features 10/100
  7. Ethernet, high speed USB host and device (OTG), microSD card, and 256MB
  8. XNAND drive. More details on the board here:
  9. http://wiki.embeddedarm.com/wiki/TS-4800
  10. The TS-4800 is supported by mainline Linux as of 4.5 and by U-boot as of
  11. v2016-07. The defconfig includes a custom 1st level bootloader located
  12. in boot/ts4800-mbrboot. This one scans the SD card's partition table to
  13. find partition having the 0xDA type, corresponding to U-boot.
  14. To build the default configuration you only have to:
  15. $ make ts4800_defconfig
  16. $ make
  17. The ouput looks like:
  18. output/images/
  19. ├── boot.vfat
  20. ├── imx51-ts4800.dtb
  21. ├── mbrboot.bin
  22. ├── rootfs.ext2
  23. ├── rootfs.ext4 -> rootfs.ext2
  24. ├── rootfs.tar
  25. ├── sdcard.img
  26. ├── u-boot.bin
  27. └── zImage
  28. The provided post-image script generates an image file containing 3
  29. partitions for U-boot, Linux kernel + device tree and rootfs
  30. respectively:
  31. $ fdisk output/images/sdcard.img
  32. Device Boot Start End Blocks Id System
  33. output/images/sdcard.img1 1 512 256 da Non-FS data
  34. output/images/sdcard.img2 513 16896 8192 c W95 FAT32 (LBA)
  35. output/images/sdcard.img3 16897 541184 262144 83 Linux
  36. This image can be directly written to an SD card.
  37. $ sudo dd if=output/images/sdcard.img of=/dev/mmcblk0
  38. In order to test the image on TS-4800 board, a TS baseboard, such as
  39. TS-8xxx the serie, is needed to provide power, console header, RJ45
  40. connector etc.
