ARM-JTAG

FEATURES

• Parallel port JTAG dongle interface, can be used with all ARM devices for programming and debugging
• uses ARM's standard 2x10 pin JTAG connector
• no need for external power supply, all power is taken from the target board
• compatible with Rowley's CrossConnect, IAR EWARM and GCC (OCD) software for programming, real time emulation, debugging, step by step program execution, breakpoints, memory dump etc everything all high priced emulators do
• with IAR EWARM you can write in assembler unlimited code size and to write in C with 16K limit for all LPC21xx arm microcontrollers
• works with free GCC C compiler and Insight toolchain and debugger
• dimensions 50x40 mm (2x1.6") + 20 cm (8") cable

HARDWARE:

• ARM JTAG connector (top view)

SOFTWARE:

The available options are Rowley CrossWorks, IAR EW-ARM, GNUARM (GCC, OCD, Insight).

• CrossWork for ARM (so far most recommended by us) C compiler and debuger from Rowley Associates, this is the easiest to use package we have tested, works smoothly with ARM-JTAG and programs both Flash and RAM on LPC21xx and many other ARM microcontrollers.
• EW-ARM C compiler and debugger (free for assembly language, 16K limit for C) from IAR Systems. Latest release can program LPC21xx Flash. C-SPY driver for ARM-JTAG have some glitches on newer and faster computers and does several crashes before connecting to target. It works fine on older and slower computers though. IAR either is not able to support Wiggler or is interested to not support it to may sell their expensive J-LINK USB tool.
• GCC C compiler from Macraigor Systems. Works smoothly with ARM-JTAG but can't program Flash and user can compile debug programs in RAM then re-build for Flash and use Philips' RS232 bootloader. It may be tricky to setup working environment by unexperienced user.
• GNUARM another GCC toolchain from Arius.
