Arduino Pro 5V and FTDI Basic and avrdude = no joy. Help?

Development Boards Arduino

I have a SF Arduino Pro 328 5V board and a “red” FTDI Basic board that works fine with the Arduino environment. However, when I try to use my avr-gcc and avrdude to program it (This is not an uncommon environment) using this invocation:

avrdude -c arduino -p M328p -P /dev/cu.usbserial-A700e5Jl -U flash:w:gen328.hex

This doesn’t work. It acts like it isn’t toggling the reset line and gives this error:

avrdude: stk500_recv(): programmer is not responding

Those in the know - Since this setup works fine in the Arduino IDE and fails outside of it, can I assume that avrdude simply doesn’t know the “DTR = reset” trigger trick? If so, how come you use -c arduino? I’m probably just showing my ignorance and assuming too much here!

Thanks all,

I hate answering my own questions… I saw another post on this topic which mentioned the baud rate. DOH. Set the -b 57600 and all works peachy.

I hope that talking to myself helps someone…

DOH!
