Schematics for the various boards. IMO such doc would be a good addition. It would help answering questions like your first one... > Do I have to add the Interface in the C-Sources, if yes what > files I have to modify? My impression is that you will. ft2232.c is the only thing you should need to change, other than adding a new tcl/interface/...cfg file for anyone else using this ICDI board.

Schematics for the B90 EK also show ACBUS0 as a VSENSE input, so the debugger can tell if there's a board there.

(System is Ubuntu, with gcc4.2.4) I'm guessing Ubuntu 8.04 or 8.04.2 with that version of GCC ... I'd just use libftdi code. You may need to install a newer version of that library though, or upgrade to a newer Ubuntu. - Dave _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
