This problem is bigger than access to your SD Card, it is basically
issue of stability communicating with whole Glamo.  The SD Card is
handled by Glamo, so it gets impacted the same.

I guess report it as a bug, but I don't think your issue is anything to
do with SD Card per se, report it as Glamo corruption issue.

That doesn't sound good at all.  If you ever see juddery or noisy screen
thing then SD Card communication is totally corrupted.

It's juddering about because of problems with Glamo DRAM, all SD Card
communication goes through that DRAM and is similarly juddered or
noised.

I've seen the same thing at various times due to not yet understood
collection of problems with Glamo memory bus.  We (olv) worked around it
by cranking up bus wait states which seems to have been pretty
effective, however I still see madness from it on resume on 2.6.26.

Have you seen this screen corruption thing before or is this the first time?

It's the first time that i've got a tv-like corruption
But one night i kept it on and connected to the power trough the power
adapter
and there was also a corruption...a little bit like when a CRT monitor has

I don't think this is enough, the damage with not recognizing the card
at boot is done by then.

If you can amend the kernel commandline in U-Boot to have

~ glamo_mci.sd_max_clk=1000

then the change will have effect from the first time the card is looked
at in Linux and I guess it will work around it.

I just ordered a bunch of 8GB cards to see if I can reproduce this and
finally solve it.

The kernel in the Om2008.8 repository is built from git revision

version, which is about 4 weeks old.

Re: SD corruption(no suspend and sd_max_clk tested)

2008-09-19 Thread Neil Jerram
This is just another SD corruption data point, and a partial one,
since I'm afraid I've lost any detailed logs.

I am running Qtopia on flash, and Debian on the SD card.  Two days ago
I found that booting into Debian failed at the point of trying to
mount the rootfs; the last message was Kernel panic..., and before
that something about not having any filesystems able to mount the
partition (/dev/mmcblk0p2).

I recovered by rebooting into Qtopia and running e2fsck on
/dev/mmcblk0p2, then I could boot into Debian again.  I'm not an
expert on fsck messages, but I think they indicated that the
corruption had mainly affected the initial superblock.

Hoping this is is of some use to somebody,

 Neil

SD corruption(no suspend and sd_max_clk tested)

2008-09-18 Thread GNUtoo
Hello,
I've bought a MMBGR04GUACY-NA and its adapter...
but the card produce I/O errors in dmesg...
I was using the kernel from FSO milestone 3
if I remember well it does the same with 2008.8

I've tried lowering sd_max_clk to the 1000
I've tried increasing the drive strength to 3

I'd really like to try debian...and for this I would need a huge sd-card

What i've done to detect it:
*boot it using the flashed FSO milestone 3 kernel and the 2008.8 userland
*install debian
when I installed debian it stoped with I/O errors
so I changed some sd settings and i restarted installing debian without
rebooting...and it made others I/O errors

How did you do this, from kernel commandline or by changing module
parameter after boot completed?
