Description
Xglamo stops working after some time, complaining "Timeout idling
accelerator...", etc.
Restarting Xglamo solves the issue. But after a while, same thing happens.

so, this patch should be applied to u-boot in OE, is that correct ?

It might not need that much waiting cycles as added by the patch. I plan to fix
that this week.
Any idea on how this can be done? It looks to me that the original settings try
to fit the timing diagram given in glamo's spec, but somehow that doesn't work.

I have added this patch to OE for now just so people can use it easilly. Kick me
if you make newer versions.

- Attachment fix-glamo-memory-timing.patch added
fix memory timing between s3c2442 and glamo
Note: See
TracTickets for help on using
tickets.
It is a memory timing issue and the patch above fixes the issue.
It adds as many as possible waiting cycles to s3c2442 memory controller. It
should be possible to lower the number of waiting cycles and find a balance
between performance and stability.
