Clawson, cool down please. In my case, as always, bootloader and main app are two separate applications, compiled separately. The main app uses bootloader code to save some space...

New avr-gcc on wrightflyer - based on AS5 (Revoked)
EW: Can we see your presentation as webcast in Internet? NY is rather pretty far away from me, but it is extremely interesting to hear something about toolchain future.

I's not necessary to use AVR32, Xmega has AES hardware acceleration too.

RE: Re: RE: Re: WinAVR continuation
Thanks. I know about mailing list, but I’m sorry to say that, but to me it seems that gcc developers are living in their own word, and it’s a problem to communicate with them...

RE: Re: RE: Re: WinAVR continuation
Hi, vtables again :) I’ve been looking into gcc internals described in online docs, and found something interesting. We already have instruction patterns, like tablejump, which...

RE: Re: RE: Re: WinAVR continuation
Probably you are right. But in that case it should be even simpler to modify. As I said, avr-gcc can perfectly work with look up tables. For example, if you have a big switch/case...

RE: Re: RE: Re: WinAVR continuation
To me vtable looks like look up table – in both cases we have a list o pointers. But look up tables are placed by avr-gcc entirely in FLASH, whereas vtables are copied into SRAM...

CPU core clock change
Yes, I will put a crystal. Just RFM22 has its own crystal, so I was thinking that it will be easy to use it.

CPU core clock change
I use RFM22 radio module, which can output selectable clock. But by default it outputs 1MHz clock, which is to slow for me, but later I can switch it to 10MHz. Do you think that...
