[U-Boot] MMC problem in PXA270 hardware

18 Jan 2010

      Hi,
I am trying bring up MMC in our hardware which is running on  PXA270
processor with 128 MB RAM.
But i am not able to detect the SDCARD, as it is showing the invalid
partition table (the dos partition magic number is not correct, it is 44aa,
instead of 55 aa), what could be the problem for such a behavior ?
But the same card is working properly in Linux on the same board.
Thanks & regards,
