RE: Problem while booting with uImage and xipImage

My board has two N25Q512A devices on it, and I am working in dual flash configuration.

I am loading "UImage" and "squashfs" image in dual flash configuration.

=> sf probe 0:1

SF: Dual SPI mode

SF: Detected N25Q512 with page size 256 Bytes, erase size 4 KiB, total 64 MiB

for writing uImage to flash:

=> sf erase 100000 280000      

=> sf write 0x0C000000 100000 500000

for writing  squashfs to flash:

=> sf erase 400000 1C00000

=> sf write  0x0C000000 400000 3800000

To use single flash of 64MB do i need to make some changes to u-boot and kernel?

Thanks
