[avrdude-dev] FTDI support in avrdude 6 (problems)

[Roman Volodchenko]

Hello everybody,

My OS windows 7 64 bit/windows XP 32/64 bit.
Programmer: FT232RL+gate section. Schematics is here:

Assembled version:

It have simple 1 side board, no chicken and egg problem, very reliable (i
use it more than 1.5 years).

First of all.
I downloaded mingw32 binary version (i tried all 6's builds) and it can't
start with next message:
avrdude: error: no pthread support. Please compile again with pthread
installed. See http://sourceware.org/pthreads-win32/.


So it's not working....
ok. Using ming32 (i tryied Cygwin also - bad result - it's build but not
working properly), src and there new problem.
If include libftdi support program can't be linked. ./configure result says
that there are pthread support, but compiler says next:
gcc -Wall -Wno-pointer-sign -g -O2 -DWIN32NATIVE  -static -o avrdude.exe

Also, looking in internet says that compiler option -lpthread should to be
in end of command.

After that i disable static linking and it's linked. I copied dll,
avrdude.exe and conf file to my folder and try to work with MCU. There are
new surprises:
1. New config format - ok. I made need changes.
2. avrdude didn't see ft programmer without changing standart ftdi inf file
to inf maded by libusb utilites. It's really bad - because FT232RL have
many pins and can be used as virtual com-port. But if i change inf file - i
can't acces to ft COMport. I have to delete device, update it inf to
standart - after that i can use COM-port, and can't use it as programmer....
There are patched avrdude 5 version with ftdi support - there is no this
problem. Plug ftdi, standart inf and you have working programmer with
COMport. And can used it.
3. After changing fuses avrdude can't see device, but when i tried to read
- it's working normall. I think delay needed little bit more.

Good news - 6 version working little bit faster (The same size flash write
on 5 version need 0.9 seconds, 6 version need 0.7 seconds). eeprom reading
problem was fixed (5 version have this problem). Also i tried to changes
fuses (switch working frequency from 1 to 8 MHz) - it's changed ok with one
problem (number 3 upper).

P.S. Can test ftdi part in future...
