[U-Boot-Users] Help with u-boot 0.4.0 and IBM ASH board

[Wetterlind, Eric]

Good afternoon...

I have an IBM ASH (NPe405h) board that I am trying to get U-Boot 0.4.0
running on. 
Ultimately, I'll port this over to our custom board that is very similar to
the ASH,
but I figured it would be better to start on a known platform.

I downloaded the new 0.4.0 U-Boot and ran these two commands (after
modifying 
the Makefile to run 'ppc_405-' instead of 'ppc_8xx'):
	make ASH405_config
	make all

It flew through compile and link to produce the nice u-boot.srec.  I put
that in 
my tftpboot directory, telnet'd over to the abatron 2000, erased ASH flash
and 
programmed this new image in there.  

The result is an immediate SystemError LED illumination.

I then switched from Flash to SRAM (one of the dips on the ASH board) and
reloaded.
Running from SRAM produces a program exception and jump to 0x700 almost
right off
the bat.  

I am running out of ideas on how to get U-boot and my ash board to
cooperate.  Has 
anyone else that has tried this had the same problems?

Regards,

U-Boot 0.4.0 is pretty old. Is there any special reson for not  using
a recent version?

Well, you h ave a BDI2000, so just fire up GDB and check what's going
on. Or single step at the BDI's telnet prompt.

Best regards,

There's an old proverb that says just about whatever you want it to.

Good idea!

Sorry, but the U-Boot ASH405 target is an "esd" custom board (PPC405EP
based) and _not_ the IBM Ash Eval Board! :-(.

I am afraid, but the IBM Ash Eval Board is not supported (to my
knowledge) right now. I don't think, that a NPe405h target is supported
at all. This should not be so hard starting from the PPC405GP.

Best regards,
Stefan.
