| 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. |
