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

[Ing. Daniel Rozsnyó]

I got no reply so I started to add the BUFF code to ft245r driver. The 
patch is in the attachment, I did some debug prints (one may not like 
the prefixes I use...) because the thing did not worked even with the 
BUFF signal.

In the end I realized, that for a low active BUFF, it would be enough to 
set the DDR to output the default zero.

Anyway, the clean ATmega32A did not responded, until I used a bitrate 
below or equal of 2400. That is strange, but now I get that:


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

 ft245r:  spi bitclk 2400 -> ft baudrate 4800
avrdude: AVR device initialized and ready to accept instructions

avrdude done.  Thank you.
