need help - malta board mips5kc

[amit lubovsky]

Hi,
I try to load a Linux image with HW debuger
(Lauterbach) to a malta board with mips5kc with no
success.
With vxWorks image it loads and run with no problem,
Any idea what is wrong?, the load address? the 'go'
address?
Thanks,
Amit.

I don't know the Lauterback tool at all, so I can
only suggest two possible things to worry about.
One would be that the debugger is making use of
memory in a way that conflicts with the download
of the Linux image.  The other would be that the
Malta drivers very likely still assume that some
set up has been done by the on-board ROM
monitor (YAMON), and that perhaps your
setup isn't allowing that to happen.  But if you
really want some help diagnosing stuff, you need
to provide more information (like *which* Linux
image, whether YAMON is still booting up on
the board before you start your session, some
description of the failure mode more detailed than
"no success", etc, etc).

I've been doing some relative work with the Green 
Hills probe and a Malta 4kc.  The configuration of 
the kernel I am using requires parameters to be 
passed in to the kernel to tell it were to find 
the root device (ie root=/dev/hda1).  To make things 
simple, I would load using YAMON, connect with the 
debugger, then set a breakpoint in a section of 
the kernel I was interested in, then run using the 
YAMON command go . root=/dev/hda1.  I plan to eventually 
figure out where it is being written to memory and just 
write it myself after downloading the image through 
the probe. 

There are many other issues you might run into when 
using Linux with a probe.  We have updated the GHS 
probe firmware to behave nicely with Linux.  This 
helps when debugging loadable device drivers, etc. 
I will forward your email to our Linux integration 
engineers to see what other issues you might run into. 
They have more experience with the Malta 5kc. 

Regards, 
Mike
