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.
