No Hex file created by avr-gcc

Hi,
I have 2 Minipov3 kits, My OS is WinXP, I'm using a USB adapter
One kit worked perfectly straight away. The other just displayed 10000000 and shifted this value about 1/sec.

I installed avrdude on my winXP machine and flashed the broken miniPOV3 with the make.hex file. It seemed to work fine, and now, both my devices work - to display "Make!"

My problem is this: I'd like to recompile so as to display different words. So, I installed avr-gcc from WinAVR-20100110-install.exe at sourceforge.net.

Now, I'm recompiling make.c using:
avr-gcc -mmcu=attiny2313 -DF_CPU=8000000UL make.c
but it doesn't create a new "make.hex" file.

I'm brand new to AVR microcontrollers, although I have some experience with PICs.

Here's my whole session trying to recompile the stock make.c file:

C:\WinAVR2\POV>
C:\WinAVR2\POV>avr-gcc make.c

make.c:134: error: 'TIMSK' undeclared (first use in this function)

----------------
so then I added -mmcu=attiny2313 to the command line
----------------

C:\WinAVR2\POV>
C:\WinAVR2\POV>
C:\WinAVR2\POV>avr-gcc -mmcu=attiny2313 make.c
In file included from make.c:3:
c:/winavr-20100110/lib/gcc/../../avr/include/avr/signal.h:36:2: warning: #warning "This header file is obsolete. Use <avr/interrupt.h>."
In file included from make.c:5:
c:/winavr-20100110/lib/gcc/../../avr/include/util/delay.h:85:3: warning: #warning "F_CPU not defined for <util/delay.h>"
c:/winavr-20100110/lib/gcc/../../avr/include/util/delay.h:90:3: warning: #warning "Compiler optimizations disabled; functions from <util/delay.h> won't work as designed"


----------------
so then I added -mmcu=attiny2313 and -DF_CPU=8000000UL to the command line
----------------

C:\WinAVR2\POV>
C:\WinAVR2\POV>
C:\WinAVR2\POV>
C:\WinAVR2\POV>avr-gcc -mmcu=attiny2313 -DF_CPU=8000000UL make.c
In file included from make.c:3:
c:/winavr-20100110/lib/gcc/../../avr/include/avr/signal.h:36:2: warning: #warning "This header file is obsolete. Use <avr/interrupt.h>."

c:/winavr-20100110/lib/gcc/../../avr/include/util/delay.h:90:3: warning: #warning "Compiler optimizations disabled; functions from <util/delay.h> won't work as designed"


So, as I said above, it seems to run with warnings but no errors, but I don't get a new "make.hex" file.

here's my version info for avr-gcc:

C:\WinAVR2\POV>avr-gcc --version
avr-gcc (WinAVR 20100110) 4.3.3

use the makefile. it will pass all the proper flags to the compiler and get the compiler output converted to a hex file.

try
Code: Select all | TOGGLE FULL SIZE
make program-make


see instructions here.
