Assuming Joachim's correct about it not mattering if you use 0:1 or 1:1 it looks like u-boot can't access your SD cleanly either, and it may be an intermittent problem since with both ext2ls and mmcinit you sometimes get the error lines and sometimes not. It will probably take a u-boot expert or a close look at the code to see what the error means, and possibly sight of the glamo documentation :-( It seems like a hardware error to me, though there's a faint possibility it's got into some odd state that's being kept alive by the backup battery. All I can suggest at this point is to check the contacts on the SD and its socket are clean, and try leaving it with the battery out long enough for the backup battery to go flat before trying again. I don't know how long that takes, but over night should be plenty. If it was long enough the rtc will have lost the time. And try mmc 1:1 just in case it makes a difference. _______________________________________________ Shr-User mailing list [email protected] http://lists.shr-project.org/mailman/listinfo/shr-user
