Subject: problems with ppc405 on 2.6.11.8.
Date: Fri, 13 May 2005 19:37:02 -0400 [thread overview]
Message-ID: <3086.1116027422@marajade.sandelman.ottawa.on.ca> (raw)
-----BEGIN PGP SIGNED MESSAGE-----
A customer of mine has a PPC405 system, which was based upon the
Embedded Planet design. It runs U-boot 0.4.0, and the system currently
ships with a kernel based upon Timesys 2.4.18.
We are in the process of upgrading to 2.6.11. (linus, not timesys. We
see no value add from timesys)
The major stumbling block was using boot/simple/{head,relocate}.S,
and the inftrees.c. For reasons we do not understand, the system would
fail in huft_build() when (setting up for) decompressing. We traced
through this using our bdi2000, after failing with puts() additions.
My gut instinct was originally that we were blowing our stack, or
overwriting running code while decompressing.
Kyle McMartin tried (I'm not sure why yet) replacing the head.S with
the one from 2.4.18-timesys. It seemed to solve the problem.
I'm posting this in two hopes:
a) that someone else not hit the same problem.
b) that someone else might have a suggestion on
what might be different between head.S+relocate.S and head.S(2.4.18).
