WARNING:

This is PRELIMINARY INFORMATION ONLY.

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.

Note:

If you are moving from a TS-7800 board to the TS-7800-V2, be sure to read the next section before continuing!

Getting Console and Powering up

Set the "EN Con" jumper, and use a null modem cable to connect the board's DB-9 connector to your workstation's COM port. Alternatively, connect a micro USB Type B cable to CN12, with the other end going to a USB port on a workstation.

DB9 The DB9 console port comprises of RS232 serial communication at 115200 baud, no parity, 8 data bits, 1 stop bit, no handshaking, no flow control.

Micro USB The Micro USB type B port hosts a USB virtual serial port on the managing microcontroller. Some users may require the OS-appropriate driver provided by SiLabs found here: https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers The TS-7800-V2 will respond over the virtual serial port at 115200 baud, no parity, 8 data bits, 1 stop bit, no handshake.

Note:

Some terminal software will default to software flow control XON/XOFF. This setting is not compatible with the TS-7800-V2. Be sure to turn off both hardware flow control and software flow control (sometimes called "handshake") when configuring the console interface for the TS-7800-V2.

Console from Linux

There are many serial clients for Linux, but 3 simple ones would be picocom, screen, and minicom. These examples assume that your COM device is /dev/ttyUSB0 (common for USB adapters), but replace them with the COM device on your workstation.

Linux has a few applications capable of connecting to the board over serial. You can use any of these clients that may be installed or available in your workstation's package manager:

Picocom is a very small and simple client.

picocom -b 115200 /dev/ttyUSB0

Screen is a terminal multiplexer which happens to have serial support.

screen /dev/ttyUSB0 115200

Or a very commonly used client is minicom which is quite powerful:

minicom -s

• Navigate to 'serial port setup'
• Type "a" and change location of serial device to '/dev/ttyUSB0' then hit "enter"
• If needed, modify the settings to match this and hit "esc" when done:

     E - Bps/Par/Bits          : 115200 8N1
     F - Hardware Flow Control : No
     G - Software Flow Control : No

• Navigate to 'Save setup as dfl', hit "enter", and then "esc"

Console from Windows

Putty is a small simple client available for download here. Open up Device Manager to determine your console port. See the putty configuration image for more details.

The TS-7800-V2 receives power through the +5VDC power connector with a 1A minimum supply. Once power is applied, the device will output information via the console. The first output is from U-Boot:

Hit any key to stop autoboot:  0     

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.

Busybox / Fastboot

After the TS-7800-V2 is first booted you will be at this shell:

 Welcome to Buildroot    
 Type 'tshelp' for help
 / #

This is a busybox shell which presents you with a very minimalistic system. This filesystem is loaded into memory, so none of the changes will be saved unless you type 'save', or mount a filesystem as read write. This can also provide a simple mechanism for running your application in an entirely read only environment. The linuxrc script will be the first thing executed as soon as the kernel is loaded. This sets the default IP address, starts the userspace ctl applications, and more. Read the linuxrc for more information.

While busybox itself doesn't contain much functionality, it does mount the Debian partition under /mnt/root/. It will also add common paths and load libraries from the Debian system. Many of the Debian applications will work by default. If an application relies on certain paths being in certain places, or running services, you should instead boot to Debian to run them.

This shell when started on the COM port is what is blocking a Debian boot. If you close it by typing 'exit', the boot process will continue. If you are connected through telnet, this will instead open up its own instance of the shell so typing 'exit' will only end that session. You would have to relink the linuxrc script to always boot to a specific partition from telnet. When logging into Debian, the default user is 'root' with no password. Technologic Systems strongly recommends setting a secure password for your system root account.

The compiled instance of busybox includes internal commands listed below:

Note:

You may want to refer to the sources for some of these commands if they are not behaving as you would expect. Busybox implements them so they are incredibly small, but they don't always provide all of the functionality as is in the standard gnu/bash shell commands. Some commands will provide the same functionality like date, but may only work with very specific formats.

First Linux Boot

U-Boot is always loaded from the onboard eMMC flash. U-Boot has the ability to boot Linux, Android, QNX, or other operating systems on the SD or eMMC. The eMMC and SD cards shipped with the unit are pre-programmed with our Debian Jessie image. See other OS sections for information on the various OS options that we provide.

Features

CPU Functionality

MMU

The 88F6020 features a Memory Management Unit, enabling high level operating systems such as Embedded Linux and Windows CE to run on the TS-7800-V2. In the same way, the Linux TS-Kernel takes advantage of the MMU functionality. The MMU is controlled by page tables stored in system memory and is responsible for virtual address to physical address translation, memory protection through access permissions and domains, MMU cache and write buffer access. In doing so, software applications can access larger "virtual" memory space than the available physical memory size, allowing multiple programs to run and use the system memory simultaneously.

Interrupts

The 88F6020 has 192 interrupts available on chip as well as another TBD implemented in the Lattice FPGA by using the doorbell interrupt register (???).

TBD

For more information about the interrupt functionalities, refer to the 88F6020 User's Guide.

Onboard eMMC Flash

The TS-7800-V2 has 4 GB of eMMC flash installed as standard.

TBD

USB Host

The USB Connector on the TS-7800-V2 provide two USB 3.0 interfaces for the user. These are directly connected to the MV88F6020 processor, which integrates a USB dual-port Extensible Host Controller Interface (xHCI), providing serial communications ports at a baud rate of up to 5 Gbit/s ("SuperSpeed"). The MV88F6020 also has a USB 2.0 controller, with Enhanced Host Controller Interface (EHCI) for full compatibility with USB 2.0 at speeds up to 480 Mbits/sec ("High-Speed").

Additional non-volatile storage may be added with a USB flash drive. This device supplies additional non-volatile storage either for data or for a complete operation system distribution, such as Debian. A tar-file of Debian is available on the Technologic Systems FTP site.

SATA

The TS-7800-V2 provides up to two SATA 3.0 ports. These allow connection of mass storage devices in excess of [some very large number goes here], at data rates of up to 6 Gbits/sec.

DDR3 RAM

The TS-7800-V2 comes with 1 GB of DDR3 as standard, with 2 GB as an option.

Realtime Clock

The TS-7800-V2 uses the Realtime Clock on the Marvell 88F6820. Linux supports this RTC with the armada38x-rtc driver.

WiFi

The TS-7800-V2 offers optional WiFi (and Bluetooth) using an ATWILC3000-MR110CA IEEE 802.11 b/g/n Link Controller Module With Integrated Bluetooth® 4.0. Linux provides support for this module using the wilc3000 driver.
