Subject: MMC on MPC8379
Date: Mon, 31 Jan 2011 13:12:29 -0700	[thread overview]
Message-ID: <4D4717AD.2040905@mlbassoc.com> (raw)

I'm running 2.6.32 on MPC8379, trying to use the SDHCI interface.
It seems to work, reads are fine, but when I write to the device
(I've tried both eMMC soldered-on and pluggable MMC/SD cards),
I get intermittent failures.  Specifically, some blocks will be
written while others fail.  I haven't yet found a pattern.

Is there anything special about this interface?  I notice that
it's not really used by any FSL platforms although the driver
claims support.

Any ideas?

Thanks
