Subject: MPC8555CDS & CCSRBAR
Date: Tue, 9 Aug 2005 07:04:27 -0700 (PDT) [thread overview]
Message-ID: <20050809140428.13450.qmail@web41211.mail.yahoo.com> (raw)
Trying to port an SEC driver to Linux/PPC8555. Reading
the default CCSRBAR @ 0xFF700000 I read 0xFFFFFFFF
which is wrong. Looking at Metrowerks init files and
uboot code (1.1.2) I see it's likely been moved to
0xE0000000, but I get a seg fault when I try to read
there.
So, what am I doing wrong, and even better, how do I
at runtime find out where CCSRBAR is? Thanks in
advance, and please forgive the likely ignorance,
Eric
