Thread: Programming ATMEL AVR fails to open interface ports

    Programming ATMEL AVR fails to open interface ports

    Has anybody been able to make AVRDude or PonyProg work directly in Debian Linux? I seem to be unable to open the I/O ports so my programmer dongles will see the chip to be programmed (Tiny 2313 and/or Mega8A). My preference would be to use the parallel port with AVRDude and a DAPA cable, but at this point I would be satisfied with almost any method and hardware that actually works.

    avrdude -p t2313 -c dapa -P lpt1 -n -v

    complains about not being able to see the AVR device being programmed.

    Re: Programming ATMEL AVR fails to open interface ports

    I've been using this makefile to build and download programs to the AVR Butterfly controller for the last several years. It seems to work well.

    (Despite having a lot of win-avr lines in it, I use it on Ubuntu with avr-gcc and avrdude without any issues.)

    Code:
    # WinAVR Sample makefile written by Eric B. Weddington, Jörg Wunsch, et al.
    
    # Released to the Public Domain
    # Please read the make user manual!
    #
    # Additional material for this makefile was submitted by:
    #  Tim Henigan
    #  Peter Fleury
    #  Reiner Patommel
    #  Sander Pool
    #  Frederik Rouleau
    #  Markus Pfaff
    #
    
    # On command line:
    #
    # make all = Make software.
    #
    # make clean = Clean out built project files.
    #
    
    # make coff = Convert ELF to AVR COFF (for use with AVR Studio 3.x or VMLAB).
    #
    # make extcoff = Convert ELF to AVR Extended COFF (for use with AVR Studio
    #                4.07 or greater).
    #
    # make program = Download the hex file to the device, using avrdude.  Please
    #                customize the avrdude settings below first!
    #
    # make filename.s = Just compile filename.c into the assembler code only
    #

    Obviously my setup is a little different than yours; I've got the device connected to a USB-to-serial adaptor (/dev/ttyUSB0), not a parallel port. Have you tried that kind of a setup?

    Re: Programming ATMEL AVR fails to open interface ports

    You need to add yourself to those groups which have the permissions to access the desired ports.
    eg: uucp for the serial port


    However, I've had a nightmareish experience with serial/parallel programmers for AVRs and I've wasted a lot of precious time in trying to get them to work correctly 100% of the time (I'm not sure it was Linux's fault)

    I suggest you buy a cheap, USB-based programmer. It will save you nerves, time and you will grow up loving programming uC, not dreading it.


    If you already have experience on Windows using these kinds of programmers, then ignore my ramble from above.

    Re: Programming ATMEL AVR fails to open interface ports

    Hi! If you are okay with using any hardware, I would suggest:
    1. PonyProg: Very simplistic hardware that will connect to the Serial Port. Does not require preprogrammed MicroController for operation. http://www.lancos.com/pplinux.html
    2. USBasp: Slightly better sophistication. Requires a preprogrammed MicroController for operation. http://www.fischl.de/usbasp/


    To setup my working environment (4 years back), I first built up a ponyprog circuit and used ponyprog to dump the firmware .hex for usbasp. I then shifted to usbasp and avrdude as I found it to be more convenient and sophisticated. Since then I have been distributing programmed chips to friends and colleagues, makes the task pretty simple.

    Also, if avrdude fails to open interface ports, the most common problem generally is the user not having permissions. A solution that works for me is running avrdude as a super user like this:
    Code:
    sudo avrdude . . .
    e.g.
    Code:
    sudo avrdude -c usbasp -p m8 -U flash:w:file.hex
