StorCenter Help?

StorCenter Help?

[Jon Loeliger]

Folks,

Anyone out there with an 8241 board such as
the IoMega StorCenter who would be willing to
help me debug my arch/powerpc cuImage problems?

I feel like I am missing something very basic in
my port... like, "Did you map this memory right?"
or "Did you set _this_ magic bit?"

I have posted the 3 patches that provide the basic
port and cuImage support as well.  The U-Boot that
I have is still legacy, so I'd like to get linux
working first via the cuImage, and then work on U-Boot.

The problem is that as soon as U-Boot uncompresses the
cuImage and loads it, I get no further console output.

The failing log follows.

And I don't have a BDI-2000 or JTAG thing I can use here.
Which is sort of why I'm tossing this out for general help.

Thanks,
jdl

Since you're getting absolutely no output after uncompression it
probably means that you're failing in the boot wrapper... which means
mmu is off, and the serial port is already set up by u-boot.

You should be able to add direct writes to the uart fifo register from
within the bootwrapper code to see how far you get in the progress.

Cheers,

So, like, the other day "Grant Likely" mumbled:

Or not getting to the boot wrapper...

Tried that.  Didn't work at all.

I think I have some variant of BAT setup failure or so.

Hmm, yet it boots a regular uImage?

weird...  Can you get *any* custom code to run *at all*?  Even if it's
just a loop that writes a char to the serial port?
