[U-Boot-Users] RE: unable to boot kernel using u-boot on MPC8272ADS

11 Sep 2005

      I am trying to boot kernel 2.6.10 (taken from kernel.org) on an MPC8272ADS board.
It hangs on a bootm command after decompressing the kernel. I'm using u-boot 1.1.3.
I've checked the BCSR value and the structure of bd_info and the kernel and u-boot values match.
What else could be the problem?

I'm still not having any luck.  I downloaded the patch and installed it and
everything looks right.
I'm trying to start the evb as if there wasn't any external ram or flash.
We have a project coming up that needs to run the 5282 in single-chip mode.
I suspect that I'm not defining the base addresses correctly or TEXT_BASE.
Can anyone help any further?

Thank you!

Read the manual at http://www.denx.de/twiki/bin/view/DULG/DebuggingUBoot

Then attach your BDI2000 and start your GDB session.

U-boot needs more RAM than 64K. Why? U-Boot copies itself to RAM and 
starts this ram copy.

That's ok with me, too. We won't change our current implementation anyway.

That's what I was afraid of.

I was able to get u-boot to start coming up.  The only way I made it happen
was by changing:
Move.l #(CFG_INT_FLASH_BASE + 0x21), %d0
To
Move.l (#CFG_INT_FLASH_BASE + 0x161), %d0

I downloaded CodeWarrior and looked at the code that was generated and that
is what they used.  I haven't looked into it at all.

Hi there,

Is there a way to know what memory segment U-boot uses (stack, etc) so I 
can give the smallest (safe) possible start address for running "mtest" 
on my memory?
