Hi Eric, Glad to hear of an impending new release. Thanks to all involved for all your efforts! > As an aside, I've heard of some issues with AVR GCC 4.5.x. You might want > to check the GCC bug list for the avr bugs to see what's been reported. Thanks for the advice. I actually had (quickly) scanned the various "open bugs" lists a couple days ago, but I think it might merit some extra attention on my part. > I think that the 4.4.x series has had more testing on the avr port, > so it might be a bit more stable. > > Also note that binutils 2.21 has just been released and AFAIK the avr patch > set has not been updated for that version (I'm in the middle of doing that > work). However 2.20.1 is the latest stable for the avr. It looks like I happened to pick a bad time to rebuild my AVR toolset. :^) When I did this (for the first time ever) about a year ago, it went more smoothly. This time around, new things like GMP/MPFR/MCP prerequisites for GCC added to the confusion, but I eventually stumbled across this recent blog entry by Jonathan Manton, which was very helpful, even though it didn't get me all the way to a working toolset: http://jmanton.wordpress.com/2010/08/08/compiling-avr-gcc-toolchain-from- scratch/ To be specific, I still had to hand-edit to the 'avr-devices.c' file for GCC to add entries for the 'atmega6490a' and 'atmega6490p' and, of course, I had to add the missing 'iom3000.h' file for avr-libc. For the time being, my avr-gcc compiler seems to be working, but I need to actually upload to an MCU and do some testing. Thanks again for the advice and info -- much appreciated.
