Hello Wolfgang,

...

$ ppc-linux-gdb

Is this really how you called GDB?

It is indeed.

...

GNU gdb 5.1.1

Where did you get this GDB from?

This version of gdb is actually the version you pointed me to a few weeks ago when I asked about debugging start.S, it does the same with the MVL toolchain as well so I suspect that maybe I've broken something.

<snip> This is probably a known problem. If you like, you can try out our latest patches; you can find a test version of our cross GDB at ftp://ftp.denx.de/pub/tmp/ppc-linux-gdb - don't forget to set the CROSS_COMPILE environment variable as needed (= ppc_82xx- in your case) as with all our ELDK tools. <snip>

As you illustrated, it should work, I think I'll take a look at what happens on our ep8260s.

thanks

Mark.
