Hi Hemant, i had add a spiflash chip to the EVM use the SPI CS1 i had modified the UBL to load u-boot image from the SPI flash so i can boot the kenel , but i have not modify the CPLD logic.

The reason is, when the (unmodified) EVM is put into PCI slot, the on-board logic automatically enables PCI (EMIF disabled). Can you clarify how are you loading U-Boot and kernel images?
