ARM Cortex-M debugger with JTAG and SWD interfaces, based on CoLinkEX

ARM-JTAG-COOCOX is an ARM Cortex-M debugger based on the CoLinkEX design. It is meant to work right out of the box with the free CooCox CoIDE. With external plugins, it also can be used with Keil MDK and IAR EW IDEs (but the driver for IAR is not perfect). Its affordable price and the ability to debug via both SWD (Serial Wire Debug) and JTAG interfaces are the key points.

ARM Cortex-M SWD/JTAG Debugger Features

• Open hardware; you have access to board design and board schematic
• Supports Cortex-M0, Cortex-M3 and Cortex-M4 devices
• Supports SWD interface
• Supports JTAG interface
• Can be used with the free CoFlash and CoIDE, or the commercial Keil MDK and IAR EW (driver for IAR not perfect)
• Compatible with both 32-bit and 64-bit Windows 7, Vista and XP
