- Technologic Systems TS-4900
- ===========================
- This document explains how to set up a basic Buildroot system for the
- Technologic Systems TS-4900 System on Module.
- The TS-4900 is a TS-SOCKET macrocontroller board based on the
- Freescale i.MX6 Single or Quad Core ARM Cortex-A9 CPU clocked at
- 1GHz. The TS-4900 features Gigabit Ethernet, SATA II Port, PCI Express
- Bus, high speed USB host and device (OTG), and microSD card.
- More details on the board here:
- http://wiki.embeddedarm.com/wiki/TS-4900
- The TS-4900 is not currently supported by mainline Linux, so a
- Technologic Systems Linux is used based on Linux 4.1.
- The default U-boot configuration flashed scans the SD card to find the
- 0x83 partition type, corresponding to the rootfs. Then it will load
- both uImage and dts from the /boot directory.
- To build the default configuration you only have to:
- $ make ts4900_defconfig
- $ make
- The output looks like:
- output/images/
- ├── imx6q-ts4900.dtb
- ├── rootfs.ext2
- ├── rootfs.tar
- ├── sdcard.img
- └── uImage
- Since both the uImage and the dts are contained in the /boot
- directory, the provided post-image script generates an image file
- containing only one partition for the rootfs:
- $ fdisk output/images/sdcard.img
- Device Boot Start End Blocks Id System
- output/images/sdcard.img1 1 524288 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-4900 board, a TS baseboard, such as
- the TS-9xxx series, is needed to provide power, console header, RJ45
- connector etc.
- The bootloader comes pre-flashed on the board on an SPI flash. Since
- updating the bootloader is risky and not trivial, it is not included
- in the Buildroot defconfig. Refer to
- http://wiki.embeddedarm.com/wiki/TS-4900#U-Boot for details on which
- U-Boot config to use and how to flash it.
