ARM ICE: Wiggler

Wiggler JTAG pod shcematic

The original device is developed by Macraigor systems. As far as I know, this is the schematic of the device, but I can't be sure, so use it at your own risk. Also, I've found this schematic on the internet and just give you it as a convinience.

GDB support

Macraigor systems also developed a utility to use GDB with the Wiggler HW. This is originaly available from here, but as a convinence I've created a ziped mirror of the Windows binaries here: DOWNLOAD. I've also added the required cygwin1.dll so you hopefully ready to go without a need to install the whole CygWin environment.
