Overview
The TS-7800-V2 is a RoHS compliant Single Board Computer (SBC) based on a Marvell MV88F6820 1.3GHz (1.8GHz optional) Cortex-A9 Dual Core CPU. On-board PCI bus provides a standard set of high-end peripherals such as 10/100/1000 ethernet, dual SATA and dual USB 3.0 ports. The Mini PCI Express connector allows for the connection of off-board mSATA or PCIe cards. The TS-7800-V2 features 1 GB to 2 GB RAM of DDR3 RAM and 4 GB eMMC flash. The TS-7800-V2 also has on-board WiFi, Bluetooth, and an accelerometer.
Getting Started
A Linux PC is recommended for development. For developers who use Windows, virtualized Linux using VMWare or similar are recommended in order to make the full power of Linux available. The developer will need to be comfortable with Linux anyway in order to work with embedded Linux on the target platform. The main reasons that Linux is useful are:
- Linux filesystems on the microSD card can be accessed on the PC.
- More ARM cross-compilers are available.
- If recovery is needed, a bootable medium can be written.
- A network filesystem can be served.
- Builds such as Linux kernel, buildroot, yocto, distro-seed will not work from WSL1/2 on a case insensitive filesystem.
WARNING: | Be sure to take appropriate Electrostatic Discharge (ESD) precautions. Disconnect the power source before moving, cabling, or performing any set up procedures. Inappropriate handling may cause damage to the board. |
Getting Console and Powering up
Get console input by setting the "EN CON" jumper, and plug a USB type Micro B cable into CN12. Connect the host side of the cable to a workstation for development. Console can be viewed before or after power is applied. Boot messages will only be printed once the device is powered on.
The cp210x (USB Serial) driver is included in most popular distributions. This will show up as /dev/ttyUSB0. For other operating systems:
The serial console is provided through this port at 115200 baud, 8n1, with no flow control. Picocom is the recommended linux client to use which can be run with the following command:
sudo picocom -b 115200 /dev/ttyUSB0
This will output some serial setting information and then "Terminal ready". Any messages after this point will be from the device via the serial output. The terminal is now ready and power can be applied in order to boot up the device.
The TS-7800-V2 receives power through the +5VDC power connector with a 1A minimum supply. Once power is applied to either the 5 VDC, or 8-28 VDC the device will output information via the console. The first output is from U-Boot:

The "SD Boot" jumper, when set, will cause U-Boot to boot to SD, and when unset, U-Boot will boot to eMMC.
Note: | The "*** Warning - bad CRC, using default environment" can be safely ignored. This indicates that u-boot scripts are not being customized. Typing "env save" will hide these messages, but this is not needed. |
