1 Technologic Systems TS-4800
2 ===========================
4 This document explains how to set up a basic Buildroot system for the
5 Technologic Systems TS-4800 System on Module.
7 The TS-4800 is a TS-SOCKET macrocontroller board based on the Freescale
8 i.MX515 ARM Cortex-A8 CPU running at 800MHz. The TS-4800 features 10/100
9 Ethernet, high speed USB host and device (OTG), microSD card, and 256MB
10 XNAND drive. More details on the board here:

13 The TS-4800 is supported by mainline Linux as of 4.5 and by U-boot as of
14 v2016-07. The defconfig includes a custom 1st level bootloader located
15 in boot/ts4800-mbrboot. This one scans the SD card's partition table to
16 find partition having the 0xDA type, corresponding to U-boot.
18 To build the default configuration you only have to:
20 $ make ts4800_defconfig
29 ├── rootfs.ext4 -> rootfs.ext2
35 The provided post-image script generates an image file containing 3
36 partitions for U-boot, Linux kernel + device tree and rootfs
38 $ fdisk output/images/sdcard.img
39 Device Boot Start End Blocks Id System
40 output/images/sdcard.img1 1 512 256 da Non-FS data
41 output/images/sdcard.img2 513 16896 8192 c W95 FAT32 (LBA)
42 output/images/sdcard.img3 16897 541184 262144 83 Linux
44 This image can be directly written to an SD card.
46 $ sudo dd if=output/images/sdcard.img of=/dev/mmcblk0
48 In order to test the image on TS-4800 board, a TS baseboard, such as
49 TS-8xxx the serie, is needed to provide power, console header, RJ45
