This commit checks -U update requests for - Typos in memory names - Whether the files can be written or read - Automatic format detection if necessary before opening the programmer. This to reduce the chances of the programming failing midway through. Minor additional changes: - Give strerror() system info when files are not read/writeable - Lift the auto detection message from MSG_INFO to MSG_NOTICE - Provide fileio_fmt_autodetect() in the AVRDUDE library - Rename fmtstr() in the AVRDUDE library to fileio_fmtstr() to avoid name clashes when an application links with it Example: $ avrdude -U - -U typo:r:.:h -U eeprom:w:testin:r -p ... -c ... avrdude: can't auto detect file format for stdin/out, specify explicitly avrdude: unknown memory type typo avrdude: file . is not writeable (not a regular or character file?) avrdude: file testin is not readable. No such file or directory |

AVRDUDE
AVRDUDE - AVR Downloader Uploader - is a program for downloading and uploading the on-chip memories of Microchip’s AVR microcontrollers. It can program the Flash and EEPROM, and where supported by the programming protocol, it can program fuse and lock bits. AVRDUDE also supplies a direct instruction mode allowing one to issue any programming instruction to the AVR chip regardless of whether AVRDUDE implements that specific feature of a particular chip.
AVRDUDE was originally written in 2003 by Brian S. Dean. Since 2006, AVRDUDE has been maintained by Jörg Wunsch, with the help of various contributors.
The latest version of AVRDUDE is always available here:
https://github.com/avrdudes/avrdude
Documentation
Documentation for current and previous releases is on Github Pages.
Getting AVRDUDE for Windows
To get AVRDUDE for Windows, install the latest version from the Releases page.
Alternatively, you may build AVRDUDE yourself from source.
Getting AVRDUDE for Linux
To install AVRDUDE for Linux, install the package avrdude
by running the following commands:
sudo apt-get install avrdude
Alternatively, you may build AVRDUDE yourself from source.
Getting AVRDUDE for MacOS
On MacOS, AVRDUDE can be installed through Mac Ports.
Alternatively, you may build AVRDUDE yourself from source.
Using AVRDUDE
AVRDUDE is a command-line application. Run the command avrdude
without any arguments for a list of options.
A typical command to program your HEX file into your AVR microcontroller looks like this:
avrdude -c <programmer> -p <part> -U flash:w:<file>:i
For instance, to program an Arduino Uno connected to the serial port COM1 with a HEX file called blink.hex
,
you would run the following command:
avrdude -c arduino -P COM1 -b 115200 -p atmega328p -D -U flash:w:objs/blink.hex:i
There are many different programmers and options that may be required for the programming to succeed.
For more information, refer to the AVRDUDE documentation.
