Hi,
I'm a bit rusty on writing makefiles, and I'm trying to write one to
compile and upload a simple blink program to an atmega48 using avrdude
and an avrisp2. However, when I run make I get the error "makefile:9:
*** target pattern contains no `%'. Stop."
I have a feeling the problem is pretty simple, but I just can't see it.
Below is my makefile. Any help is greatly appreciated.
CC=avr-gcc
CFLAGS=-g -Os -Wall -mcall-prologues -mmcu=atmega48
OBJ2HEX=avr-objcopy
TARGET=blink
PART=m48
PROGRAMMER=avrisp2
program : $(TARGET).hex
avrdude -p $(PART) -c $(PROGRAMMER) -e flash:w:$(TARGET).hex
%.obj : %.o
$(CC) $(CFLAGS) $< -o $@
%.hex : %.obj
$(OBJ2HEX) -R .eeprom -O ihex $< $@
clean :
rm -f *.hex *.obj *.o
