WinAVR and AVR toolchain are different tool chain packages made by different people.

Atmel would presumably say that Studio itself is so good at generating Makefiles there'd never be any need to use Mfile. It is, however, a shame that things like Mfile, avrdude and many of the gnuwin32 utilities are missing from their distribution as it always forces an installation of WinAVR20100110 alongside to get all the things they missed.

For Mfile specifically, you can download it from it's home: http://www.sax.de/~joerg/mfile/

I guess you need the AVR Toolchain from Atmel for support for new(ish) devices? If not, then an alternative would be to skip AVR Toolchain altogether and use WinAVR-20100110.

Or you could continue to use AVR Toochain but for the side-dishes missing from it have a parallel WinAVR installation.

For the time being that seems to be it, yes. While the world is moving towards modularized stuff Atmel is going monolithic.. They have talked about more modularization of Atmel Studio, but that seems to imply starting with Studio, and you want it the other way around - a separate download for AVR Toolchain - so there might be less hope for solving your situation.

Finally: There was talk about a new WinAVR build a while back but nothing has been heard about it lately..

Brilliant info, Dean! (Our mole in the ministry is doing well :mrgreen:)

EDIT: I see it is dated June 2011. Is that the version that ships with Atmel Studio 6?

No it is not(Even 5.1 ships with 3.3.1.27) Maybe we can find a standalone download somewhere else.

I've just emailed the Toolchain developers asking for the latest version to be put up. Their office is now closed for the weekend, but hopefully I'll receive a response Monday.

My (and Thomas') aim is to be some Atmel engineers that Freaks actually like ;). Hopefully with us on the inside we can help out better here and make everyone a little less grumpy.

Microchip users are forced to download MPLAB in order to write their codes for PICC compilers from Hi-Tech, because their command line is a serious PITA. Now Atmel is following the same policy, but unfortunately creating more chips that hobbyists can never use, contrary to Microchip, interesting... Also squeezing us on the software we have to use, more and more interesting...

I was feeling very comfortable with WinAVR "Ok, I did not like the icons ;- )", and seems I will just go back to it. Technically speaking, does avr tool chain offer major improvements or it is just the newer chips support?

One thing, why is WinAVR no longer updated? Everyone who used WinAVR alone, knew very well that they did not want to use that silly studio..

abcminiuser: Why does Atmel ask me to give my email in order to download software? Most large companies are doing this, and most of us ended up creating a dummy email for this dumb policy that we never check unless we register to download some software... Just you know...

I do feel sorry for what things turned out to be these days, much effort, and less satisfaction.

Signature: We need more peripherals in DIP packages. Namely, USB, 12-bit ADC, 16-bit timer, cheaper tool as a programmer/debugger coz STK600 is expensive! Atmel Studio 5/6 sucks! coz it brings MS visual studio crap to AVR world..

How so? The maXTouch chips aren't sold to the unwashed masses, but all the rest generally are.

Bug fixes and device support. You can install the new toolchain and use your old makefiles from WinAVR, if you keep WinAVR installed and preferenced second in your PATH variable.

The creator, Eric (EW) got hired at Atmel, and a dedicated toolchain team has taken over.

As far as I can see, there is

Support of Xmega core
Tentative support of tiny Tiny core
Optimized support of some fixed point types
Support of AVR-specific built-ins
Support of nmi function attribute

I could not find documentation of nmi attribute anywere, so maybe nmi is just noise on the sources...

There was an announcement in https://www.avrfreaks.net/index.p...

I don't know what was the reason for the delay; AFAIK there was no WinAVR release after 20100110 (avr-gcc 4.3.3).

Such a release is a lot of work so that alone might already be a good reason for why there is no new WinAVR yet.

Moreover, it was unclear what GCC base version would be best. Maybe just waiting for 4.7.0 release to base a new WinAVR on; would make much more sense than 4.6.3 because:

Tentative support of Xmega core
Tentative support of named address spaces like __flash
Better optimization
Support of AVR-specific built-ins

GCC 4.7-branch has been created just now, so that we can expect 4.7.0 release very soon.

How to modify the makefile to be able to compile an asm file. Code is written for use with AVR-GCC in assembler mode, I never came across compiling assembler file only under AVR-GCC, I am used to compiling c files indeed, and I am no expert with assembler.

You just change the extension to .S (that is upper case) and add it to a normal "C" project. avr-gcc knows to hand off any .S files to avr-as

I'd prefer the solution as mentioned in the source:

-x assembler-with-cpp

Under windos I'd avoid .S extension becuae it meght get messed up with .s. If you cannot add -x assembler-wih-cpp, you can also use extension .sx which is detected as "assembler with preprocessor" like .S.

Some notes on the code:

The ISR messes up SREG. You will get wrong additions in the main loop because of messed-up carry.

Instead of

down_ten:
	sbiw	r24,10		
	clr	r23
	sbc	r26,r23
	ret

you can write

down_ten:
	sbiw	r24,10		
	sbci	r26,0
	ret

You can let the binutils machinery setup the vector table for you:

#include 

#define SFR(X) _SFR_IO_ADDR(X)

.text

;; Interrupt Service Routine (ISR)
;; Vector Names are defined in avr/io.h
;; The binutils Machinery will setup the Vector Table for you

.global TIMER2_COMPA_vect
TIMER2_COMPA_vect:
    ; Toggle PORTB.0
    sbi SFR(PINB), 0
    reti

Thank you all indeed, this is a great help to me, I appreciate all the replies, seems people here have extremely good knowledge :- )

I attached makefile, main.c and minidds.S files. There are too many errors when I compile :?

SprinterSB:
I hope I cound have more understanding of what you said, but I did not know how to apply all the things you said, sorry :?

You should stop for a while and look at what you are trying to do.

Instead of using Makefile that are more complex than Linux kernel, write it yourself or use a simple shell script.

If there is a small (but obvious) error you will drown in the flood of messages...

Don't include assembly in a C file.

Okay, I removed the include of assembly file from main.c as you suggested, and I added #include in the assembly file as well, things have changed much indeed:

minidds.S:169: Error: number must be positive and less than 64
minidds.S:172: Error: constant value required

Look at _SFR_IO_ADDR() as shown in this example:

http://www.nongnu.org/avr-libc/u...

but read this:

http://www.nongnu.org/avr-libc/u...
http://www.nongnu.org/avr-libc/u...

You may prefer the "#define __SFR_OFFSET 0" solution (I do).

I read them, the example shows how to declare variables in assembler and C files in order to use them in both files, this is not what I need. I only need to compile this assembler file under avr-gcc. Using a main.c will be meaningless indeed, because the code in this assembler file is already complete. There must be a way to compile an assembler file under avr-gcc without the need for a c file. I can't figure out what the command line should look like.

Just compiler it:

avr-gcc main.S -mmcu=atmega8 -o main.elf

or, if you frefer other extension:

avr-gcc -x assembler-with-cpp main.asm -mmcu=atmega8 -o main.elf

This will use avr-gcc as driver to call assembler and linker. You get the C run time as explained in this example:

#include 

;; Redefine __SFR_OFFSET to 0 so that we
;; get I/O Addresses instead of RAM Addresses
;; for SFRs that are I/O-addressable by
;; IN, OUT, SBI, etc.
#undef __SFR_OFFSET
#define __SFR_OFFSET 0

;; Some convenient Macros

#define F_CPU       1000000
#define IRQs        1000
#define PRESCALE    8

.text

;; The Startup-Code calls main
.global main

Thanks a lot. I replaced:

.org 0
rjmp	RESET

with

.global 	main

and changed:

RESET:

to

main:

Then I used this command line:

avr-gcc.exe -x assembler-with-cpp minidds.asm -mmcu=attiny2313 -o minidds.elf

Now to produce hex file, I executed this command:

avr-objcopy.exe -j .text -j .data -O ihex minidds.elf minidds.hex

Is omitting .org 0 Ok?
Also, are the command lines I am using correct, is there any thing I am missing?

.org is deprecates since 20 years now...

The commands look reasonable. Also look as a disassembly, e.g. with avr-objdump -d minidds.elf to see if everything is in order.

Thanks SprinterSB.

BTW, how can I show the size of the hex file and memory used?

The size of teh hex file is not interesting. Wat is interesting is the size occupied on the device. For data in static storage and code you can use avr-size. For dynamic data there is no general clue. Static code analysis is an option but not all programs can be statically analyzed.
