When you say Serial, do you mean USB or RS232? I have not used gnoduino, but with had no problem compiling and uploading to Arduino Mega2560 over USB on Arch using avr-gccand avrdude. This is the avrdude settings I use: avrdude -c stk500v2 -p atmega2560 -b 115200 -P /dev/ttyACM0 -U flash:w:program-file.hex (You will need the root privileges for this). Attached the makefile if it helps you to get an idea. Sudaraka Wijesinghe On 07/17/2012 01:43 PM, andrea crotti wrote:
I'm trying to use my arduino mega2560 with arch but there's no way to get it working yet.. I installed the arduino 1.0.1-1, and everything seems to work, until I try to use the Serial, when I get (compiling from gnoduino):
avr:5 architecture of input file `/tmp/build1342512569.47XizyI/core.a(HardwareSerial.cpp.o)' is incompatible with avr:6 output collect2: error: ld returned 1 exit status
I saw about a bug in avr-gcc but it should have been fixed long time ago, and it's probably not the same thing... Anyone got it working?
