The TS-7550 is a ultra-compact embedded computer module based on a 250MHz ARM9 CPU from Cavium Networks. In comparison to the TS-7400, it is less expensive, about half the size and over 50% faster. The TS-7550 offers additional features such as High-Speed USB host and device, 256MB XNAND flash and 5K LUT programmable on-board FPGA. The 44-pin header allows an external board to interface with the TS-7550 via DIO lines or FPGA cores. Please, contact us for further information. Hardware Description
The TS-7550 features a 250MHz Cavium ARM9 CPU and a 5000 LUT Lattice FPGA.
With 64MB RAM and a bootable 256MB on-board flash with our new XNAND technology the
TS-7550 is a powerful and extremely reliable embedded solution. External devices can
connect to the TS-7550 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 44
pin downward-facing general-purpose header makes it easy to interface the
TS-7550 with a base board of your own design. Using just under 400mA at 5V, a
TS-7550 driven product can be fully powered by a USB device cable.
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-7500 FPGA configuration for an elegant and affordable solution.
The TS-7550 development kit includes the
TS-ENC750 enclosure with the TS-752 base board. The TS-752 base board
demonstrates the power of the TS-7550, implementing Relays, RS-232, RS-485,
power over Ethernet, and signal protection for DIO.
The standard TS-7550 FPGA configuration implements the following features:
- up to 8 UARTs (XUARTs*)
- SPI
- Watchdog timer
- up to 33 DIO lines
Differences between TS-7500 and TS-7550
The TS-7500 and TS-7550 are very similar products. The TS-7500 has a MicroSD Card whereas the TS-7550 does not. The TS-7550 instead includes 256MB of NAND flash with our XNAND technology for ultra-reliability.
XNAND Technology
Technologic Systems XNAND technology is a 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 or MLC 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. There is also one serial port in the CPU for a total of 9 serial ports. |

The TS-7550 SBC boots to Linux 2.6 from onboard Flash
using the proprietary TS-BOOTROM bootup firmware residing in ROM memory. 4MB of the
onboard Flash is used to store a bootable Kernel image and a initial ramdisk
image. A bootable NAND flash 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-7550 software
features include:
- Boots Linux 2.6 out-of-the-box in less than 3 seconds (to a shell
prompt).
- Un-brickable design ensures 100% recoverability from external flash of TS-752 in case of
onboard flash erasure.
- Startup Linux mini-root scripts allows flexible root and backup filesystem
selection (NFS, USB flash) as well as software field upgrade
support.
Linux OS Support
Technologic Systems TS-7550 ARM Single Board Computer (SBC) is 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 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-7550 functions are included.
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 SD
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-7550 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-7550 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.
