Dear Huang Changming-R66093,

Reposting _AGAIN_ because you again discarded the U-Boot ML address.

I don't know why, I replied to all, not discard any address.

Dear Huang Changming-R66093,

...

Andy, Do you agree my suggest to revert these codes to fix this issue?

Please ... do us all a favor, read [1] and stop being so inconsiderate of others! Given that I can no longer make any sense of this thread because of your top-posting making it complete utmost mess, my opinion is NAK on reverting them.

[1] http://www.ietf.org/rfc/rfc1855.txt

Then, could you give some suggest, how to fix the 12bit-width issue?

see drivers/mmc/mmc.c:

1089 width = ((mmc->host_caps & MMC_MODE_MASK_WIDTH_BITS) >> 1090 MMC_MODE_WIDTH_BITS_SHIFT);

Fix this snipped of code and the related code below ... that's the way to go about it.

Yes, I can change these codes to: Width = EXT_CSD_BUS_WIDTH_8;

Then, first value of width will be 2.

But, those modification is I said, the codes is reverted to the old codes.
