I have a serial ISP programmer of protocol type "stk500v1" which expects 115200 baud data rate. I have used it successfully with Atmel Studio by calling avrdude manually (custom tool) in the past. This just involves the avrdude option
But recently I wanted to do use the Arduino software instead of Atmel Studio for a quick mockup. But everytime I try to "Upload with Programmer", the avrdude commandline includes the option
and so the programming fails.
I can make it work by changing the hard wired serial rate in the programmer from 115200 to 19200, but then of course the programming is dead slow, which I don't want.
I have also looked for a baudrate entry for stk500v1 in "avrdude.conf", but didn't find any. How can I change the baud rate for "Upload with programmer" in the Arduino software?
