Subject: mmc0: unrecognised SCR structure version 1

Hello,

using MMC/SD support on my PXA270 based board I get this error:

mmc0: unrecognised SCR structure version 1

when I insert a MINISD card.

I tried to find on the net some specifications for the SCR structure
version 1 but I found nothing useful... someone has a similar problem
or can suggest to me where I can find such specifications?

Thanks,

Rodolfo

To my knowledge, no such version exists. So either your card is broken or you
have some transfer problem on your board. What's the name of this card and have
you tried any others?

I suppose the same... but this is the only cards who gives me such
problems! What do you think it could be the problem? Maybe some PXA
MMC special settings?

The card is a 512MB MiniSD by Viking InterWorks.

Thanks,

Rodolfo

I'm afraid I have little experience with PXA. Perhaps you can find
someone on the linux arm kernel mailing list with more insight?

Sounds like a fairly common card. Cards so broken that they give an
incorrect scr version should be rare, so I would guess that there is
some transfer problem with the PXA. I don't suppose you have any other
linux based platforms to test the card in?

I already asked for.

Unluckily not! :'(
