Zylin社製 ZY1000 JTAG Debugger 定価
\128,000
The ZY1000 is an easy to use stand-alone JTAG
Debugger and flash programmer. It communicates with your computer over TCP/IP.
This enables the ZY1000 to be used with any operating system: Windows, Linux,
Mac OS, Solaris and others. The flash programming capability requires only a web
browser, whereas for debugging only GDB is required on the host operating
system.
The ZY1000 supports the ARM7, ARM9,
ARM11, XScale and Cortex M3 line of processors. Support for
all the processors is included in the ZY1000 at no extra cost.
It's web GUI covers tasks such as flash
programming, production, testing, diagnosis and hardware development/debugging.
ZY1000 Start web page with status summary.
The hardware developer, tester or production
team members will be able to upload new firmware as quickly and easily as the
software developers and the software developer will no longer have to develop
special procedures for the rest of the team.
The ZY1000 comes with support for a wide range
of flash devices, including CFI flashes. With a few lines of code you can add
your own flash driver should a driver for your flash device not be included.
In order get you quickly up and running with the
ZY1000 and debugging your target, the ZY1000 includes configuration scripts for
a wide range of target boards. These scripts are made for setting up the
complete board... not just the CPU.
The ZY1000 has 3 different modes of operation
that can be combined as needed. Setup of both the target and the ZY1000 is done
using the easy to use web interface. The web interface can also be used for
common tasks like resetting the CPU, programming the flash, or browsing/editing
the target memory. If you prefer to use a command line interpreter, you can
connect to the telnet server.
Software developers can use the GDB-server for a
full feature debugger with all the features available in a modern debugger. This
means integration into your design environment, like Eclipse or Insight, and the
ability to set hardware and software breakpoints, single-step, and browse
variables, memory and CPU registers.
With a JTAG speed of up to 32 MHz, and upload
speeds (GDB load) over 400 kBytes/s, the ZY1000 is fast for both flash
programming and debugging. With the image already uploaded to the ZY1000, target
programming reaches 1.1mBytes/s @ 16MHz. The actual performance depends on the
target.
Equally important as throughput/bandwidth is GDB
single stepping performance. The ZY1000 has been designed to maximize the GDB
single stepping performance by reducing the latency of smaller requests. GDB
will issue a number of small requests during single stepping to fetch various
information such as registers, local variables, etc.
There is no hassle involved with starting to use
the ZY1000. Just power up, set the IP address of the ZY1000, and you are ready
to connect it to your target!
