Linux Atmel AVR Simulator with GUI
There is the nice simulator VMLAB, which is basically a Windows application,
but it runs smoothly in Linux with WINE. Since the avr-gcc version for Windows, WinAVR,
did not install in WINE, I used the coff option in VMLAB (set that option when creating a new project).
Making a COFF out of an ELF binary is not supported by avr-gcc (avr-objcopy) by
default so you need to look for the "cdk-avr-binutils" for your linux distribution.
Most likely there is a package out there.
In order to avoid overwriting of the avr-gcc binaries by the cdk-avr-binutils package,
I just unpacked the .deb/.rpm file and used the avr-objcopy binary in a custom
directory.
MCU=atmega16
CC=avr-gcc
OBJCOPY=avr-objcopy
# optimize for size:
CFLAGS=-g -mmcu=$(MCU) -Wall -Wstrict-prototypes -Os -mcall-prologues
TARGET = adc-noise
# path to your VMLAB project directory in WINE
VMLABDIR = ~/.wine/drive_c/avr/adc-noise/
# location path of avr-objcopy which supports the coff-avr option
OBJCOPYCOFF=/path/to/cdk-avr-binutils/avr-objcopy
all: adc-noise.hex
adc-noise.hex : adc-noise.out
$(OBJCOPY) -R .eeprom -O ihex adc-noise.out adc-noise.hex
adc-noise.out : adc-noise.o
$(CC) $(CFLAGS) -o adc-noise.out -Wl,-Map,adc-noise.map adc-noise.o
adc-noise.o : adc-noise.c
$(CC) $(CFLAGS) -Os -c adc-noise.c

--change-section-address .noinit-0x800000 \
--change-section-address .eeprom-0x810000
coff: $(TARGET).out
$(COFFCONVERT) -O coff-avr $< $(TARGET).cof
cp -f $(TARGET).c $(VMLABDIR)
cp -f $(TARGET).hex $(VMLABDIR)
cp -f $(TARGET).cof $(VMLABDIR)
Troubleshooting:
avr-objcopy: adc-noise.cof: Invalid bfd target
Problem: You're not using a coff-avr option enabled avr-objcopy
Solution: Use the "cdk-avr-binutils"
