I have same setup and same toolchain, but Fedora Core version is 4.
Where your EDK/XMD is running? Mine is on Windows XP machine connected
to the same L2 switch.

So do I.

Well, mine allows me to connect, set one break point and continue. But
as soon as breakpoint is reached, any further command (next, step,
continue) kills the session and target doest run either:

[leonid@mylinux u-boot]$ /opt/mb/bin/mb-uclinux-gdb -nw u-boot

Target doesn't do anything after this "continue".

Can you think of any other differences between our setups? Some special
EDK settings you had to do? BTW, what card you are working with? Mine is
Spartan-3e Starter Kit (though I also tried on proprietary Spartan-2e
based board with same success) connected via USB ) speed up to 24000000
bps.

Thanks,

Leonid.
