I did try setting the clock lower, (e.g., sd_max_clk=500, even
250), but that didn't help.
Keep going to 1/5 of the last value. Does that help? A 2GB card I bought
was only stable at about that clock rate.
At 1/2 of that last value, I think

Hi all,
I have problems accessing my 8Go SD Card
following different advices found in the wiki and the mailing list, I
managed to change env in uboot
after boot :
[EMAIL PROTECTED]:~# cat /proc/cmdline
glamo_mci.sd_max_clk=1000 rootfstype=jffs2 root=/dev/mtdblock6

Hi Nicolas,
search the list(s) or the wiki for the various parameters in ( I think )
/sys/module/glamo_mci/parameters/ :
It boils down to either setting idle_clk=1 prior to suspend to avoid
getting the MBR trashed, and/or reducing the sd cards max speed on bootup to
get the card recognized

What helped me was setting up another menu entry in u-boot adding to the
bootargs:
glamo_mci.sd_drive=3 glamo_mci.sd_idleclk=1 glamo_mci.sd_max_clk=500
rootdelay=5
The relevant part was sd_max_clk ( might work with higher value, but is ok
as is for me) and the rootdelay, after that the card
7 matches
