Hi, here are my comments: * Do you have a particular purpose for the JTAG_OE signal? I can't see the point of letting the cable put all the JTAG wires in high impedance mode, so in my opinion this feature should be removed. Or, at least, the cable should be driving the JTAG pins by default so that we don't have to modify usual FT2232H JTAG software for this cable to work. * You might want to add ESD protection devices on USB and UART (the JTAG level translator is already quite ruggedized itself) and connect the shell of the USB connector via a 1M and 4.7nF 250V resistor and capacitor in parallel for improved noise immunity (as recommended by USB spec).
Otherwise, all seem OK to me, good job :) Thanks, Sébastien _______________________________________________ http://lists.milkymist.org/listinfo.cgi/devel-milkymist.org IRC: #milkym...@freenode Webchat: www.milkymist.org/irc.html Wiki: www.milkymist.org/wiki
