Hi All,
There is a problem still exist when you try to use avr-gcc with devices which has more than 64k of the flash memory.
Whole problem is described in the thread:
http://www.avrfreaks.net/index.php?name ... highlight=
Is it possible to apply patches from above thread ? |

But did you follow the link to the GCC bug report?
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45263
Georg-Johann Lay (SprinterSB on this board) fixed it in April 2011. So GCC versions issued after that should have the problem fixed. Maybe try one of his 4.7 builds? |

I built the avr-gcc tools using the script on this thread to build the 4.5.1 version. It built several compiler executables including avr-gcc, avr_g++, avr_c++. Arduino is giving me the following error:
error: Cannot run program "avr-g++":, the manual states a missing avr-gcc-c++ program. Maybe it expects a simlink to avr-c++ or avr-g++? Any ideas? |

I seem to have avr-c++, avr-g++, and avr-gcc in /usr/local/avr/bin as you do but the arduino ide gives me the error:
"Cannot run program "avr-g++" java:io Exception:error=2, No such file or directory. My path is set so I can find these files from a user terminal shell why can't the Arduino IDE find it? Maybe it's looking on a specific path but I don't know what that is?
The arduino site says to install avr-gcc-c++ whatever THAT is.
Maybe a simlink to something else? |

NB Atmel have a 4.6.2 for Linux (and Windows) available at:
http://www.atmel.com/tools/ATMELAVRTOOL ... LINUX.aspx
this is the same toolchain that is found in the first release of AVR Studio and is not bad (like some of their previous attempts) and has the advantage of supporting a lot of new AVR models like the USB enabled Xmegas and the small tiny4/5/9/10/20/40 devices. |

Cliff,
We're current users of 30-Apr-2010 toolchain (gcc version 4.3.4), though we really only use the compiler, not the debugger or loader (we just use avr studio for a bootloader once).
Is there much of an advantage to Atmel's new toolchain to warrant changing for new projects (targets are generally xmega A4 series).
I did see a code space saving:
Old:
Code:
Size after:
AVR Memory Usage
----------------
Device: atxmega128a1
Program: 29822 bytes (21.4% Full)
(.text + .data + .bootloader)
Data: 2478 bytes (30.2% Full)
(.data + .bss + .noinit)
New:
Code:
Size after:
AVR Memory Usage
----------------
Device: atxmega128a1
Program: 28844 bytes (20.7% Full)
(.text + .data + .bootloader)
Data: 2478 bytes (30.2% Full)
(.data + .bss + .noinit)

p.s. The script and the ubuntu package is excellent. It saves us a huge number of hours in sorting out our own toolchain on Linux. The effort is deeply appreciated. |

| I wouldn't change for changes sake but if you pick one of the new AVRs then I think this is the only toolchain that has support for the additional models. |

ftp://ftp.dkuug.dk (for binutils and gcc) Seems to be down. Permanent or just wait?
Its the getfiles.sh that fails.
I may resolve it for binutils by using this link instead (or?)
ftp://ftp.gnu.org/gnu/binutils/binutils-2.20.1.tar.bz2
And for gcc link
ftp://ftp.gnu.org/gnu/gcc/gcc-4.5.1/gcc-4.5.1.tar.bz2
Or has it been done changes to the archives that would bring me troubles if using the mentioned ones... I downloaded today, 5.aug...
By the way, if no changes, why not use the above as default in the script? |

Actually, I got something similar too, though it was on an upgrade from 11.10 to 12.04. The fix is to remove the blank lines in the offending control files (mine were the dpkg cache files over an upgrade where it broke), but it should be fixed more permanently.
