We have the DbAu1200 evaluation board from AMD.
With the help of the buildroot utility project http://buildroot.uclibc.org we have successfully:
- crosscompiled / booted the Linux 2.6.11-r00058 kernel sources (from AMD which include patch for the db1200)
- crosscompiled / booted the Linux 2.6.16 kernel (vanilla sources)
Building the AMD Alchemy Au1200 MAE drivers and tools was also possible with the same tools but when we want to start the maiplayer front end for the mae driver we get this message:
* The source tar.gz used was: amdms2-1.0-01.02.75-src.tar.gz
MAIplayer - console-based player using MAIengine
According to this document 40351a_dbau1200_openemb_appnote.pdf (from AMD's developer's website), It is possible to build en entire Linux system for this platform using the OpenEmbedded project http://oe.handhelds.org
AMD Have on their developer's website a tool kit for the Au1200/DbAu1200 for OpenEmbedded which is mainly a set of patches and config files for their specifics hardware, processor and piece of software like mae drivers and a patched 2.6.11 Linux kernel sources for au1200. (the kit used was: au1200-dev-kit_v1.0-r3.tar.gz)
The catch is that OpenEmbedded is a very active project and a daily snapshot of the development archive is available and the older snapshots are kept for about 30 days. The problem is the AMD's OpenEmpedded toolkit was based on a quite old snapshot (oe_20050727083537.tgz) July 27th 2005 and most of the patches doesn't apply anymore to the current OE snapshots.
We managed to manually patch what is blocking the compilation of openembedded by disabling things that aren't important four our needs and finally we where able to boot this openembedded linux for db1200.
And we had the same poor results for the MAE Driver as we had with buildroot earlier. (We built OE with either glibc or uclibc)
We have chosen to use OpenEmbedded for theses reasons;
I am desperately seeking help before diving into debugging this MAE thing (wich is supposed to work)
