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.
On the surface, it looks like it should work and I'm perplexed
by the failures.
Does anyone have any ideas or experience with this device?
