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.
