I am trying to use avrdude 5.11.1 on i386 Linux (Ubuntu 12.04) with an FT2232D wired tp an AT90S2313 in accordance with FTDI’s MPSSE application note AN_135 (which in summary says pins 23->MOSI, 22->MISO, 24->SCK, 21->nRESET).
But I am absolutely baffled as to what port to specify. I know to use -p avrftdi -p 2313 and be the superuser (until sensible permissions can be assigned anyway). If I put usb:999 or even complete garbage after the -P I don’t get any kind of meaningful error but does seem to know whether I have the FT2232D plugged in regardless of -P. It looks as if port selection is somehow completely automatic and -P is ignored. What if I have more than one FT2232D ? I cannot find clear documentation on how to specify the port for accessing this kind of device beyond a mention of usb:N which doesn’t seem to do anything. Maybe I have failed to find the right documentation. There is a reasonable chance the hardware has a silly mistake as last night was a late one but I would like to know I’ve got the software end right as well so would appreciate some input (and improved documentation for the next person).
