The TS-7558-BOX 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-7558-BOX is a powerful and extremely reliable industrial embedded solution. External devices can
connect to the TS-7558-BOX via Ethernet, USB, RS-232, RS-485, or CAN.
The TS-7558-BOX can be powered by PoE or by a DC power supply anywhere in the 5-30V
range. An internal microSD slot allows for expanded storage.
The rugged screw-down terminals provide the following interfaces:
- 8 opto-isolated digital inputs (0-30V)
- 4 opto-isolated digital outputs (0-40V)
- 4 analog inputs (0-5V, 0-10V, 4-20mA)
- power supply input (5-30V)
The digital inputs can act as edge counters, quadrature decoders, ADC triggers,
or simple inputs. The outputs can be used for PWMs. The TS-7558-BOX also provides
an internal header with the following functionalities:
- Debug console
Rugged Plastic Enclosure
Available with a DIN mount, the enclosure makes the TS-7558-BOX ready
for immediate deployment. The enclosure label clearly identifies the pinouts
on the rugged screw terminals.
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
The TS-7558-BOX FPGA programming is open-source. If the many features provided in
the standard load don't meet the needs of your application, you can modify the
FPGA logic or hire Technologic Systems to do so for you.
Upon bootup, the default software automatically checks for an FPGA bitstream
and loads it if it is present, overriding the default FPGA programming. To
create your own bitstream, you need only the following resources:
for more instructions on FPGA development.
The TS-7558 SBC boots to Linux 2.6.24 from either a microSD card or on-board XNAND
drive. The 256MB on-board 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-7558-BOX software
- 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 on-board XNAND drive erasure.
- Startup Linux mini-root scripts allow flexible root and backup filesystem
selection (microSD, NFS, USB flash) as well as software field upgrade
The TS-7558-BOX ships with a full-featured, open source data acquisition
driver utility called daqctl. This utility gives full control over a wide
variety of TS-7558-BOX hardware features including ADC, PWMs, quadrature, counters,
and timestamped glitch detection. The FPGA can easily be programmed to
interrupt the CPU under a wide variety of external conditions.
A data acquisition network service is also
supported, allowing for software control on a remote system.
Linux OS and Debian Support
Technologic Systems' TS-7558-BOX ARM Single Board Computers (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 ship 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-7558-BOX functions are included. In addition, the full Debian
binaries and services are available from the initial ramdisk after mounting the
The TS-7558-BOX SBCs are configured to load Debian "Lenny" Linux from the on-board
XNAND drive or microSD card during boot up time. The on-board XNAND drive 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.
CAN Bus Support in User Space
The TS-7558-BOX 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-7558-BOX 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..)
