DM/AM37x EVM TF card boot up error

Hi, all

      I used a TF card( encapsulated with a SD  cover, 4Gbyte, sandisk )  to start up a DM/AM37x evm.

     The tool is from the dvsdk 4.02, and using the prebuild image.

     When boot up it can have the following erors:

lost page write due to I/O error on mmcblk0p2

mmcblk0: error -110 sending read/write command, response 0x900, card status 0xe00

mmcblk0: error -110 transferring data, sector 1917293, nr 24, card status 0xc00

end_request: I/O error, dev mmcblk0, sector 1917294

Buffer I/O error on device mmcblk0p2, logical block 229621

lost page write due to I/O error on mmcblk0p2

end_request: I/O error, dev mmcblk0, sector 1917301

Buffer I/O error on device mmcblk0p2, logical block 229622

lost page write due to I/O error on mmcblk0p2

end_request: I/O error, dev mmcblk0, sector 1917309

Buffer I/O error on device mmcblk0p2, logical block 229623

lost page write due to I/O error on mmcblk0p2

mmcblk0: error -110 sending read/write command, response 0x900, card status 0xe00

mmcblk0: error -110 transfer

        For the first time boot, it can boot up with many error messages and the demo matric can't toot up.

        For the second time boot, it will have kernel panic, the detailed message is attached.

         If I used the sd card to boot with the same procedure, there is no any errors.

        So could any one give some suggestion on it?

        In my opinion, it should be the driver is not so good...

  Thanks!

    Is this a brand new card or one you've had for a while?  I'm assuming that like the demo cards MLO/u-boot and the kernel were loaded off the card so we can rule out things like the card not being fully seated in the SD cover.  Assuming a brand new card, can you please tell us what class/etc it is?  If you post the full dmesg the information will be in there.  Thanks!
