AW: [En-Nut-Discussion] Just a minor patch...

[Radek Podgorny]

Harald,

the tools I use come AFAIK from the CD I got with Ethernut 1.3 box I bought 
some time ago. The bad thing is that I can't check now because the CD is 
lost. Stupid me. Anyway, my OS is linux. Versions follow:

avr-binutils-1.12.90.20020708
avr-gcc-3.2.0.0-20020708
avr-gcc-c++-3.2.0.0.20020708
avr-libc-20021118cvs

I found the defines you were talking about but the TCCR0 ones were like CS10, 
CS11, etc. which looks strange. I'm downloading the latest tools right now to 
check it out...

...after a while...

...so, my new tools:
avr-binutils-2.14
avr-gcc-3.3
avr-libc-1.0.2

The iom1028.h file seems to be fixed now (just like yours)...

I'm sorry for wasting your time. My fault. I should have stayed up-to-date 
with the latest avr-libc...

Sincerely
Radek Podgorny
