I test SD card driver for uClinux with the NEEK board.
When I start the board is OK. (SDHC 2.0 Class 4 4GB)

When I redownload the hardware and software image to the board, it is error:

I try a few times, it show same error.
Only press the power, it show ok in first times.
But I use 128MB or 256MB SD card to test the driver.
These are ok with "Ctrl+C".
The problem is SD card 2.0's problem? Or else?
BTW: I aleady used the up to date driver. I update it today.
