Like thousands of others, avrdude shows the hallmark output:
avrdude: Send: 0   avrdude: Send: 0   avrdude: Send: 0   avrdude: ser_recv(): programmer is not responding avrdude: stk500_recv(): programmer is not responding
I'm trying to move away from the toy ide and towards make and the avr/gcc toolchain on linux. The problem is not hardware... it is probably some setting (other than bitrate) that I just don't get. I am pretty sure of this because the arduino ide can burn the blink project, but I can't seem to find the right command line for avrdude. I've been using:
/usr/local/arduino-1.0.1/hardware/tools/avrdude \ -C/usr/local/arduino-1.0.1/hardware/tools/avrdude.conf \ -patmega2560 -carduino \ -P/dev/ttyACM0 -b38400 \ -D -F -v -v -v -v -V \ -Uflash:w:~/tmp/marlin.hex:i
Yes, /dev/ttyACM0 is correct (arduino uses ttyACM0). I've tried bitrates from 9600 to 115200. I can get the same failure/success under windows using avrdude under cygwin and the windows arduino ide. I'm sure the answer is a simple one. Thanks in advance.
