Just a quick summary of our JTAG meeting: http://www.hackerspace.be/JTAGNight 1. we managed to get JTAG access on a WAP54G and WRT54GS with an Olimex adaptor with all the pins connected, needed to get 3.3v from the serial port pin, Intel flash support is missing on both routers, we also tried urjtag.exe on windows and it was working fine. 2. we did not managed to get JTAG access ("TDO stuck at 1" message error) with the Amontec Jtag key tiny, despite having the same pinout, I tried to add some 82K pullup resistors, without any luck, there is an R7 2 pads connector, we tried to strap it (the Olimex has a 0k resistor in there), but no change For some pictures, see here: http://www.flickr.com/photos/zoobab/sets/72157622918012427/ If someone can help with the Amontec JTAG key configuration, I can try to share the exact pinout by looking at the pictures. Maybe there is a trick I don't know yet wtih the Amontec. -- Benjamin Henrion <bhenrion at ffii.org> FFII Brussels - +32-484-566109 - +32-2-4148403 "In July 2005, after several failed attempts to legalise software patents in Europe, the patent establishment changed its strategy. Instead of explicitly seeking to sanction the patentability of software, they are now seeking to create a central European patent court, which would establish and enforce patentability rules in their favor, without any possibility of correction by competing courts or democratically elected legislators." ------------------------------------------------------------------------------ This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev _______________________________________________ UrJTAG-development mailing list UrJTAG-development@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/urjtag-development
