Subject: [U-Boot-Users] Problem with cache diag on sequoia board in PPC4xx branch for-1.3.2
Date: Thu, 20 Dec 2007 17:31:36 -0500 [thread overview]
Message-ID: <476AED48.9060303@arlinx.com> (raw)
Hi Stefan,
In testing my merge of Korat PPC440EPx board support into PPC4xx branch
"for-1.3.2", I found problem with the "DIAG RUN CACHE" command. The
same problem occurs in the latest for-1.3.2 code for sequoia. Here is a
copy of the console output showing what happens:
=> diag run cache

This problem does not occur on sequoia using the latest mainline (i.e.,
master branch) code from the PPC4xx repository.
Just thought you'd like to know. :-)
Best regards,
Larry
