Celebrating 25 years of emulation systems design!
JTAGjet-ARM is a non-intrusive In-Circuit
Debugger for all AT91 ARM7 and ARM9
based devices. It features:
• High-speed USB 2.0 (480 Mbps) interface
allows downloading to target RAM at rates
exceeding 1 MBytes/sec.
• Chameleon Debugger for ARM7 and
ARM9 with integrated NOR and NAND
Flash Programmer.
• AT91 Peripheral device register window
gives detailed information about register
bits, bit fields and their descriptions.
• Based on high-speed logic (FPGA)
JTAGjet is optimized for fast downloads, fast
window refreshing and instruction stepping.
• Support for all popular (over a dozen) 3rd
Party Debuggers & Compilers.
• Up to 30 MHz JTAG clock with Adaptive
Clock support (RTCK).
• Virtual-to-physical address mapping
support for ARM cores with MMU
(essential for WinCE, PalmOS, OSE or
Linux operating systems).
• JTAG chain diagnostics for device
detection, identification and troubleshooting.
• Active JTAG probes support long and noisy
JTAG chains.
JTAGjet-Trace has the same features as
the JTAGjet-ARM but adds real-time trace
memory.
• Supports the AT91RM9200 and other
devices that contain the ETM (Embedded
Trace Macrocell) trace port.
• Non-intrusive trace capture at up to 400 MHz
CPU speeds.
• Up to 4M frames deep trace memory
(18 MBytes) captures the entire program
flow (PC) and all data transactions
(variables and CPU registers) in real-time.
• 56-bit, cycle-accurate time-stamp is
added to each frame to show detailed
execution timing as well as frequency of
execution of any function or interrupt.
• Pre- and post-capture trace filtering with
simple and intuitive user interface.
• Export trace data to Excel file for further
analysis and graphing.
• Quiet operation - no heat problems,
no fans.
• One connection to target via the
standard 38-pin Mictor connector.
• Single, palm sized unit - both the emulator
and the trace are in one enclosure.
• USB 2.0 interface
• Supports all major debuggers
• Integrated Flash programmer
•
Multi-core support
•
Cycle accurate trace up to 400 MHz
• Up to 4M frame deep trace
• 56-bit time stamp, cycle accurate
• ETB support
