it seems that some cards don't connect well to the sd socket.

it shouldn't be a bug of driver.

Is it also a hardware problem?

 

--- Vivi Li                                                  2009-02-11 05:56:18

The card failed just now has started to work again. It seems like the hardware

problem.

 

I tried 5 cards here, only one card never works(an orange SanDisk 256MB SD

card).

Great.

 

--- Vivi Li                                                  2009-07-02 02:24:09

On latest bf518f-ezbrd board version 0.2, SD cards can all be detected.

 

--- Vivi Li                                                  2009-07-02 02:26:33

OK now. Close this bug.
