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