Re: [Avr-eclipse-user] What versions of eclipse/cdt are known to work with AVREclipse?

Hi,

I can confirm that avrEclipse works with Helios. My set-up is Ubuntu 10.04 running under VMWare on a 
WIN7 host. On the host the ATMEL jtag USB driver has been replaced with the usblib driver from 
winAVR (C:\WinAVR-20100110\utils\libusb\bin)

On Ubuntu I have:

eclipse-cpp-helios-SR1-linux-gtk.tar.gz

and (just, no other plugins)

avreclipse-p2-repository-2.3.4.20100807PRD

To setup for debugging using an ATMEL JTAG ICE MK2 I load the hex onto my target and kick off 
avarice in a linux terminal window with:

avarice --erase --file myprog.hex -2 --ignore-intr --jtag usb :4242

OR if the target is already flashed:

avarice -2 --ignore-intr --jtag usb :4242

Then follow the "Debugging on the target/Helios" instructions in

http://embedded-linux.co.uk/tutorial/eclipse-cross-compile

The only difference being:

GDB Debugger: avr-gdb
Connection: TCP, localhost, 4242

Pressing "Debug" brings up the debug perspective with the source code window on main(). Breakpoints 
work.

I imagine the same set up will work directly on Windows/WinAVR/Helios though I've not tried it.

Cheers, Steve.
