initrd problems on CLLF860T, please help.

[Zheng, Haifei]

Hi there,

We are trying to boot our CLLF860T board with an initrd. We are using Monta
Vista Hard Hat (kernel 2.2.14) and we built out own ramdisk image. ( I know
there is an example ramdisk.image.gz from Hard Hat but haven't found it) and
we are getting the following boot messages:

Page table -> SDR1

[Sébastien Côté]

Hello again,

Can someone explain me how the base address for the page table is set ?
Looking at hashtable.S, it should be set to 0x180000 and be 256 kB long.
However, when SDR1 is set in turn_on_mmu (head.S), they use _SDR1 to set
the value but I couldn't find anywhere where _SDR1 is set!

Also, when I check the value in the register SRD1, the HTABORG part (bits
0-15) show 0xE so this isn't 0x180000.  Finally, the value of HTABMASK
(bits 23-31) doesn't correcpond to what is recommended in the PowerPC book
from Motorola for 32 MB of RAM and a 256 kB page table.

To me, it seems like the page table isn't set up correctly but since I
don't really understand how it is done, maybe I'm wrong.  I would also be
very surprised to get that far (jumping to the first instruction of init)
without page table.  A little help about this would be very appreciated.

Well, this kind of tells you something, doesn't it?  Either you
don't have an init program of some type (even /bin/sh), or you don't
have enough shared libraries on the ram disk and the program can't
be loaded properly (although you often get messages about not able
to load some .so).

To start up /bin/sh, which is a good thing to try initially, you
need the entire glibc RPM from the CDK and libtermcap.so.  You also
need that funky sym link:
	/opt/hardhat/devkit/ppc/8xx/powerpc-hardhat-linux -> /
in the target filesystem.

This one comes up pretty often, so I've added a mention of it in the HOWTO
(including a link to Joe's cool ldd script) at:
    http://penguinppc.org/usr/embedded/howto/PowerPC-Embedded-HOWTO-20.html

pls make sure you have the link in
/opt/hardhat/devkit/ppc/8xx/powerpc-hardhat-
linux -> /
you can check it in the past mailling list
hope this help,
Jari
