Follow-up Comment #13, bug #41561 (project avrdude):

I just tried it (SVN version) using my own USBasp device.
Uploading a large (about 100 KB) file to an ATmega2560 worked
fine:


% ./avrdude -C avrdude.conf -c usbasp -B1 -p atmega2560 -U lorem.elf 

avrdude: set SCK frequency to 750000 Hz
avrdude: AVR device initialized and ready to accept instructions

avrdude: Device signature = 0x1e9801 (probably m2560)
avrdude: NOTE: "flash" memory has been specified, an erase cycle will be

avrdude done.  Thank you.


Alas, my device doesn't tell me which firmware version is
beign used.  I think it is the 2011 version, because I
remember the reason I built my USBasp was to test the TPI
stuff in AVRDUDE.

For reference, I also appended my -vvvv logfile.
