Subject: Manually setting timings on PDC20269
Date: Thu, 21 Aug 2003 18:01:26 -0500	[thread overview]
Message-ID: <3F454F46.3000207@sbcglobal.net> (raw)

Hi,

Is there any way to manually set the UDMA timings used to interface with 
a drive?

I can see in the PDC20269 driver that it is responsible for setting the 
timings, but I'm not sure how to adjust them at runtime.  My UDMA-2 
drive reverts to PIO after trying a write.  Oddly, I can read from the 
drive using UDMA, it just times out and reverts to PIO when I try to 
write anything to it.

This is with kernel 2.6.0-test3...

Thanks,

Wes
