Date: Wed, 18 Jan 2006 21:04:45 -0200 Hey guys, We're trying to make a miracle : flash an undocumented Z80 processor through JTAG. The silicon is the ATJ2085 - the chip that powers the chinese "s1 mp3 player" There is a real problem : we need Z80 JTAG specification. If there is an electronics expert who know Z80 and can help, please, read the todo list: http://www.s1mp3.org/wiki/index.php/Talk:ICE/JTAG_how_to There are lots of missing info, but the most important are the JTAG register sizes. If you think you can contribute it anyways, please, edit the wiki page with new information! Thanks and I hope some of you can bring us any light! *project home page : www.s1mp3.org *project wiki : wiki.s1mp3.org -- Wladston Viana Ferreira Filho Belo Horizonte - MG, Brasil Visit the project: s1mp3.orgReceived on 2006-01-19 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
