I've been shown a new dev kit for the AVR AT327000 that uses embedded linux and I wanted to get advice and opinions on this processor. I'm not familiar with AVR processors at all. I'd like to use the GCC compiler. Is this well supported? Does anyone know who's done the Linux port and is it well supported? I'd like to use this also outside of an embedded linux environment. Is it a good choice? (I know that's a pretty general question.) I've found avrfreaks.net, any other good sites? Dan

I am not familiar with the AT327000 and I found no mention of it on Atmel's website so perhaps you intended to type something like AT32AP7000. N.B. AVR32 processors (which seem to be what you are thinking of) should not be confused with AVR (8 bit) processors: thank Atmel for the confusion. "I'd like to use the GCC compiler. Is this well supported?" GCC is fairly well supported for AVR (if you use the patches in the FreeBSD ports, the GCC steering committee does not care about AVRs and has let patches wait for over a year) but it is flawed. I do not know whether AVR32 is supported. "Does anyone know who's done the Linux port and is it well supported? [..]" I do not know. "I've found avrfreaks.net, any other good sites?"

Is this well supported?I have not used GCC on the AVR32 AP7000 but have on the AVR32 UC3A - which is its little brother. See here: http://www.freertos.org/portAVR32.html There is a basic WEB server running that uses lwIP on top of FreeRTOS.org.

They're $70 from Digi-Key.> I'd like to use the GCC compiler.

I've tried using "buildroot" to build an root filesystem but haven't had any luck with it. Bob

Just after the tools not an ide. Avr gcc is easily available both binaries and source. Any plans to make the sources available so they can be built for other systems ? Alex
