If you have never used it before,\u00a0avr-size<\/a> is a very useful command that\u00a0does a relatively simple thing – it tells you how large your compiled avr-gcc programs are. \u00a0This is very useful knowledge when you are trying to fit as much code as possible into a part with only a few K of flash memory. \u00a0Additionally, the actual flash footprint of an AVR program is not something you can easily distill from a .hex file. \u00a0Hex files are usually much larger than the actual compiled code due to the overhead of that file format.<\/p>\n

avr-size comes with the binutils-avr package in Ubuntu (and is installed as part of WinAVR and CrossPack on Windows and OSX, respectively). \u00a0Unfortunately, Ubuntu 10.04 (Lucid Lynx) ships with a broken version of avr-size that doesn’t include the necessary patches to support the AVR.<\/p>\n

To see if your avr-size is working, open a Terminal in Lucid and try executing this command on a compiled avr-gcc .elf file of your choice:<\/p>\n

avr-size -C --mcu=attiny2313 main.elf<\/strong><\/code><\/p>\n

You’ll probably see something like this:<\/p>\n

avr-size: invalid option -- 'C'

Bad news, but it’s not surprising. You have the broken version of avr-size that comes with binutils-avr for Lucid.<\/p>\n

The solution:<\/h3>\n

I was able to fix this issue by installing the binutils-avr package for Debian Squeeze, an approach I learned about from\u00a0this Ubuntu bug report<\/a>.<\/p>\n

To download the Debian binutils-avr package, either go to the Debian package repository<\/a> or execute this command:<\/p>\n

wget \"http:\/\/ftp.us.debian.org\/debian\/pool\/main\/b\/binutils-avr\/binutils-avr_2.20.1-1_amd64.deb\"<\/strong><\/code><\/p>\n

Now install the package by double clicking on it or executing:<\/p>\n

sudo dpkg -i binutils-avr_2.20.1-1_amd64.deb<\/strong><\/code><\/p>\n

If you tell Ubuntu to “hold” the package you just installed, it should stop trying to revert to the broken version in the Lucid repository every time you run a system update:<\/p>\n

echo \"binutils-avr hold\" | sudo dpkg --set-selections<\/strong><\/code><\/p>\n

You can check the hold status by running<\/p>\n

sudo dpkg --get-selections | grep binutils-avr
\n<\/strong><\/code><\/p>\n

The status should be shown as “hold” (not “install”).<\/p>\n

Now if you run avr-size, you should see the special AVR option ‘-C’ is now present.<\/p>\n

It works! \u00a0You now have a working avr-size command for Ubuntu.<\/p>\n

There is a good chance this package will eventually be fixed in the Lucid repository, but based on the bug report above, it could be a while (2012?) before we see an update. \u00a0Until then, installing the Debian package seems to be a good solution.<\/p>\n

If anyone reading this is close to the Ubuntu package maintainers, can you please kick them about this issue?<\/p>\n","protected":false},"excerpt":{"rendered":"
