The TS-4500 is a macrocontroller board based on a 250MHz ARM9 CPU
from Cavium Networks. The TS-4500 offers features such as High-Speed USB
host and device, 256MB XNAND drive, MicroSD card, and 5K LUT
customizable on-board OpenCore FPGA. Hardware Description
The TS-4500 is a low profile credit card sized Macrocontroller module and
features a 250MHz Cavium ARM9 CPU and a 5000 LUT Lattice FPGA. With 64MB RAM
and a bootable 256MB on-board flash drive with our new XNAND technology, the
TS-4500 is a powerful and extremely reliable embedded solution. External devices can
connect to the TS-4500 via Ethernet, USB host, USB device, or I2C ports as well
as DIO, UARTs, and SPI which are implemented in the standard FPGA load. The two 100
pin downward-facing general-purpose headers make it easy to interface the
TS-4500 with the TS-8200 base board or a base board of your own design.
The standard TS-4500 configuration implements the following features:
- 53 3.3V GPIOs on TS-SOCKET interface
- 3-8 TTL XUART* serial ports
- 1 CAN controller (requires offboard transceiver)
- DMX Support
- SPI Support
- I2C Support
- Watchdog Timer
- Real-Time Clock (off-board battery)
- Temperature Sensor
- 256Mbyte onboard XNAND flash drive preloaded with Debian Linux
Does your application require custom real-time logic such as non-standard bus
interfaces, PWM outputs, quadrature decoding, pulse timing, or digital
counters? Technologic Systems can integrate that functionality into a custom
TS-4500 FPGA configuration for an elegant and affordable solution.
TS-SOCKET Description
TS-SOCKET is an embedded computer standard designed and controlled by Technologic Systems, Inc. It defines both a form factor and a connection pin-out and is based on two 100-pin low-profile connectors, allowing secure connection between a Macrocontroller (CPU board) and a baseboard. Please refer to the TS-SOCKET Standard and Embedded Macrocontrollers resource for more information.
Differences between TS-4500 and TS-75XX
The TS-4500 is a Macrocontroller module version of the TS-75XX Cavium ARM9
CPU/Lattice XP2 core. This board is low profile and about the size of a credit
card, but includes no connectors/jacks except for the pair of 100 pin high
density board to board connectors. Like the TS-7552/TS-7553, this module has
both the 256MByte onboard flash and microSD socket.
XNAND Technology
Technologic Systems XNAND technology is an ultra reliable and industrial grade user-space device driver that uses Reed-Solomon codes, extra checksums, and a RAID based technique to allow any Linux filesystem to be used with confidence on SLC NAND flash. Our TS-BOOTROM can also boot from XNAND for an ultra-reliable bootup. Please refer to the XNAND whitepaper for more information.
* Technologic Systems XUART core is an extended UART core supporting 7, 8, 9, or 10 bits per character, Tx and Rx FIFOs 256+ characters deep, and accurate measurement of idle and busy times. These ports support advanced protocols such as DMX/RDM. |

The TS-4500 is a macrocontroller board based on a 250MHz ARM9 CPU
from Cavium Networks. The TS-4500 offers features such as High-Speed USB
host and device, 256MB XNAND drive, MicroSD card, and 5K LUT
customizable on-board OpenCore FPGA. Software Description
The TS-4500 SBC boots to Linux 2.6.24 from either a MicroSD Card or onboard XNAND
Drive. The 256MB onboard XNAND Drive is enough to store a bootable Kernel image,
initial ramdisk image, and a minimal version of Debian "Lenny" Linux. Storage
memory can be expanded through the MicroSD Card socket. A bootable MicroSD Card
must contain a Linux Kernel image, a initial ramdisk image and a valid Linux
root filesystem. The fast Linux bootup solution was optimized for speed and
includes kernel, initrd and filesystem (Busybox) tweaks. Since this board boots
to an initrd (initial ram disk) with a read-only mounted filesystem, it is
possible to have something other than a shell prompt running after bootup by
editing the /linuxrc shell script on the initrd. Additional TS-4500 software
features include:
- Boots Linux 2.6.24 out-of-the-box in less than 3 seconds (to a shell prompt).
- MicroSD card pre-installed with minimal Debian "Lenny" Linux distribution.
- Un-brickable design ensures 100% recoverability from MicroSD card in case
of onboard XNAND drive erasure.
- Startup Linux mini-root scripts allows flexible root and backup filesystem
selection (MicroSD, NFS, USB flash) as well as software field upgrade
support.
Linux OS and Debian Support
Technologic Systems TS-4500 ARM Single Board Computer (SBC) are compatible
with a wide range of Operating Systems (OS's). The Linux choice is highly
recommended and our products are totally integrated with the open-source vision.
The boards ships with Linux 2.6.24 Kernel running out-of-the-box. There is no
proprietary source code in the kernel since all the hardware specific
functionalities are handled by user-space utilities. The Linux kernel includes
driver support for on-board hardware, enabling quick time to market of end-users
applications. Examples and source codes are also available for downloading.
The compact initial ramdisk filesystem is based on Busybox and uClibc and is
improved for performance and flexibility. Specific Linux scripts and utilities
that handle the TS-4500 functions are included. In addition, the full Debian
binaries and services are available from the initial ramdisk after mounting the
MicroSD Card.
The TS-4500 Macrocontrollers are configured to load Debian "Lenny" Linux from the onboard
XNAND Drive or MicroSD Card during boot up time. The onboard XNAND Flash uses
a minimal Debian "Lenny" Linux distribution that has been compacted to fit in
the 256MB space and leave about 70MB free for the user and includes utilities such as apt-get for installing and removing
programs. The MicroSD card uses a full featured Debian "Lenny" Linux
distribution which includes a complete GNU C/C++ embedded development
environment. In addition, Apache Web Server, FTP, SSH, Telnet and Samba network
services are available with C/PHP/Perl for embedded CGI development.
Eclipse IDE for TS-7000 and Windows
The Eclipse IDE configured for embedded development with the TS-7000 ARM9
computers running Debian Linux is provided along with the 2GB development
MicroSD Card. Technologic Systems makes use of the Eclipse Europa release and
the DSDP+CDT plugins in order to provide an advanced IDE and makes embedded
development easier. ARM crosstool chains, cygwin runtime-libraries and a Java
Development Kit are installed on the card, therefore Eclipse IDE will run
out-of-the-box (no need for installation) in your Windows PC. The Eclipse
environment is already configured to allow a quick startup with a TS-7000
embedded development. After start-up, the installed 'helloworld' example shows
the user how to use the Eclipse functionalities, including cross-compilation,
build-management configurations, binary download to the TS-7000 target, target
management via SSH, FTP, telnet or serial console, client-server debugging with
Eclipse debug view, etc.
CAN Bus Support in User Space
The TS-4500 utilizes an SJA1000C-compatible FPGA core out of the box complete
with documentation and sample code.
The sample code provides a simple utility to send/receive CAN packets and perform
useful and common functions with the CAN bus from userspace. Additionally, this
sample code includes network CAN service and can be automatically started on
TS-4500 bootup which makes the writing of CAN enabled applications even simpler
and furthermore allows for the possibility of development in languages other
than C (Java, Python, etc..) and on systems other than the local Linux SBC
(Linux/x86, Windows, etc..)
Please contact Technologic Systems for further information regarding
Operating System and software support for this product.
