Hi Jerry, That being said, a weekend with a logic analyzer on a BDI2000 JTAG connection would probably give you all the info you need to figure out the appropriate JTAG commands. The problem is that it is going to be different for every processor family and it may even change between

Hi, There has been shown interest on the OpenOCD mailing list (last week or so) to reverse engineer the PowerPC COP JTAG commands, so that OpenOCD could support PowerPC architectures as well. If there is a developer on that list in need of hardware, give him my email, and I can send one of
