Hello All,

I am using ATmega329 but WinAVR-20050214 doesn't suppport it.

My requirements are very modest, I've rewritten my code so that I only need
support for the ATmega329 memory map:

FLASH  0x0000 - 0x3FFF
SRAM   0x0100 - 0x08FF
EEPROM 0x0000 - 0x03FF (This is now unimportant)

I set -mmcu=atmega32 and substituted iom329.h instead of iom32.h but the
SRAM began at 0x0060 instead of 0x0100, so it was no good. Niether
was -mmcu=atmega323. In fact no supported micro matched the SRAM

I am therefore resigned to performing a build of avr-gcc and have at least 3

1.  I have a Slackware 10.1 linux box available and can use instructions &
patches at http://www.kieltech.de/uweswiki/

2.  I have downloaded FreeBSD 6 and can use Joerg Wunsch's work at:

3.  I can be really masochistic and try a windows build using instructions

I cannot find any Windows build instructions on the WinAVR home page or
WinAVR project page so must assume Eric Weddington wants to keep this a
secret. Perhaps a Windows build is such a pig, that this is a deliberate
ploy so that he isn't besieged with questions day-&-night :)

Which option do people recommend ?
