I'm trying to connect a JTAG emulator and debugger up to a BitsyX board. I was told by one of the ADS engineers that there are some additional components in the JTAG chain before the PXA255 processor. How many devices are there and how many instruction registers are on each component so that I can setup my emulators correctly to step through the Xscale processor?
Our products include application-level debuggers for Linux and Windows CE, so you shouldn't need a board-level debugger.
If your application development requires JTAG emulation/debugging, please drop us a line with details about your requirements and we'll be glad to help.
