[Feng Tang (feng-tang)]

several points need clarification:
1. Is the code based on Intel MSS(MMC/SD/SDIO) stack?
2. If answer to 1 is yes, is it the latest code base on moblin.org?

1. Is the code based on Intel MSS(MMC/SD/SDIO) stack?
Yes
2. If answer to 1 is yes, is it the latest code base on moblin.org?
The code released on Aug 15

[Feng Tang (feng-tang)]

"The code released on Aug 15", is it the code on moblin.org/kernel-mid.git?, we usually only put our latest patch in that git

[Feng Tang (feng-tang)]

I just check in some fix to the moblin.org, please help to verify it fix the bug

[rob rhoads (rob-rhoads)]

Feng: if this bug has been fixed, please update the status to fix.

[Feng Tang (feng-tang)]

As it's reported on Midinux 2.0, I have no way to verify it directly. I verify it on moblin-kernel, most card are OK, except some card claimed with extra protocol brand like "MMC Plus" "MMC Elite".

So now I'd change the status to "fix commited"

[Jing Wang (jing-j-wang)]

Hui, on moblin kernel, per my check, SD card can be recognized correctly. How about your side right now? if this issue disspear, please let me know.

[rob rhoads (rob-rhoads)]

Confirm this fix on CB w/ Moblin kernel and close this bug. RF Midunix doesn't use moblin's kernel.

[Jing Wang (jing-j-wang)]

Verified on moblin kernel w/ CB
