I would first check the board schematic and make sure all the JTAG lines are hooked up appropriately and have correct pull-up/downs where necessary.From there, you would need someone more familiar with the ARM7/9 JTAG commands to figure out what it is trying to do.Well, the pins are properly pulled high and low. Is it possible that the device ID is correctly read while the hardware is faulty? The wiggler cable is good since I tested it with another board with a different CPU. -- brian ------------------Cool-Karaoke - The smallest recording studio, in your palm, open- sourcedhttp://cool-idea.com.tw/xoops/ck-product.php iMaGiNaTiOn iS mOrE iMpOrTaNt tHaN kNoWlEdGe
My knowledge of the JTAG protocol and physical interface is pretty minimal. In theory it would be possible to get corruption like that, but I suspect it would be difficult. Could you add "debug_level 3" to your config file and rerun it. That should provide a lot more information about what is happening.
