[avrdude-dev] ftdi_syncbb issues: no BUFF, wrong chip?

[Ing. Daniel Rozsnyó]

Hi,
 I have some issues with the FT232 programmer code.. I had to define a 
custom pinout, and the BUFF pin is not recognized. Is that okay, or the 
ftdi_syncbb does not support the BUFF pin?



programmer
  id    = "kac-cmos";
  type  = "ftdi_syncbb";
  connection_type = usb;
  miso  = 7;  # /DCD
  sck   = 4;  # /CTS
  mosi  = 6;  # /DSR
  reset = 5;  # /DTR
  buff  = 8;  # /RI
;


results in -v printout of:

         Programmer Type : ftdi_syncbb
         Description     :
         Pin assignment  : 1..8 = DBUS0..7, 9..12 = GPIO0..3
           RESET   =  5
           SCK     =  4
           MOSI    =  6
           MISO    =  7


 And the second issue is, that after that the text goes like:

 ft245r:  spi bitclk 75000 -> ft baudrate 150000
avrdude: ft245r_program_enable: failed
avrdude: initialization failed, rc=-1
         Double check connections and try again, or use -F to override
         this check.


  The chip I am using is however a FT232RQ:

I am using:
avrdude: Version 5.11svn, compiled on Aug 13 2012 at 21:14:46
(with FT2232 in custom configurations it works perfectly!)
