trying to compile USBTINYISP with winavr

[ckeays]

Please help, I have been trying for 6 hours to compile the code from usbtinyisp with winavr.
I am getting an error like this:

Code: Select all

> "make.exe" all
avr-gcc -Os -g -Wall -I. -I../usbtiny  -mmcu=attiny2313 -c ../usbtiny/crc.S
avr-gcc -Os -g -Wall -I. -I../usbtiny  -mmcu=attiny2313 -c ../usbtiny/int.S
avr-gcc -Os -g -Wall -I. -I../usbtiny  -mmcu=attiny2313 -c ../usbtiny/usb.c
avr-gcc -Os -g -Wall -I. -I../usbtiny  -mmcu=attiny2313 -c -o main.o main.c
avr-gcc -g -mmcu=attiny2313 -o main.elf crc.o int.o usb.o main.o
process_begin: CreateProcess(NULL, python ../usbtiny/../util/check.py main.elf 32 2048 128, ...) failed.
make (e=2): The system cannot find the file specified.

make.exe: *** [main.hex] Error 2

Can someone help me? I want to compile the code for a 90S2313 because I don't have any atiny2313.

-mmcu=attiny2313

Don't you need to change this before you make?

-mmcu=attiny2313

Don't you need to change this before you make?

The problem is it won't compile the way it is right now without changes.

process_begin: CreateProcess(NULL, python ../usbtiny/../util/check.py main.elf 32 2048 128, ...) failed.

what on earth are you putting in for the chipburning to make it try to run " python ../usbtiny/"?

I am not sure what you mean.

I thought I would just compile it the way it is exactly as I downloaded it. (unzipped, a folder is created called usbtinyisp. I copied this folder to c:\winavr.) I did not modify the files in any way until I can compile them successfully.

FIRST I wanted to see if it would compile the way it is before I made any changes.

Of course someone compiled this because there is a hex file included, so I know it's possible!

I am using WinAVR-20081205.

Please help!

A Python program is used to validate the build. You could install Python or edit common.mk so it does not call check.py...

Code: Select all

Change this:

main.hex:   main.elf $(UTIL)/check.py
   @python $(UTIL)/check.py main.elf $(STACK) $(FLASH) $(SRAM)
   avr-objcopy -j .text -j .data -O ihex main.elf main.hex

to this:

main.hex:   main.elf
   avr-objcopy -j .text -j .data -O ihex main.elf main.hex

Thanks, that worked. HOWEVER, now the hex file is too big for the attiny2313!
here is the end of the hex file:

Code: Select all

:1007F0009F908F907F900895949A80E781BBBFDD92
:0C08000080E582BBC4DDFECFF894FFCF82
:02080C00D25ABE
:00000001FF

as you can see, its too big! I am by no means a "C" guy (obviously).
Is there a command to "optimize code" or something?

I would love to have this code in assembly!

An older version of AVR GCC is required to make it fit. Much of the code is already in assembly.

From http://www.xs4all.nl/~dicks/avr/usbtiny/ ...

I initially used gcc-3.4.3 with the -Os option, which generates reasonable compact code. Unfortunately, newer versions like gcc-4.1.0 generate about 10% more code, and as a result, the application code did not fit in 2K anymore. To make it fit, I had to remove the optional vendor and device strings, by undefining the USBTINY_VENDOR_NAME and USBTINY_DEVICE_NAME macros.

I downloaded WinAVR-20060125 and it worked! The code now runs in a 90S2313!

IF anyone would like the hex file, I can post it (if it's okay with the mods here)

Thank you for your help!
