AM3354通过GPMC读取FPGA数据的问题

Other Parts Discussed in Thread: AM3354

准备用AM3354的板子和FPGA通过GPMC总线通信,FPGA作为norflash设备,使用了CS1 ,采用的是Synchronous Burst Read Access,通过cs和oe来控制数据读取,用示波器也能看出来GPMC总线上是有数据发送的,但是FPGA上对应片选的地址空间数据都是零,GPMC的配置参数如下,

GPMC_CONFIG1_1                            0x78001200        
GPMC_CONFIG2_1                            0x00000B00
GPMC_CONFIG3_1                            0x00000200
GPMC_CONFIG4_1                            0x00000B03
GPMC_CONFIG5_1                            0x010A000B
GPMC_CONFIG6_1                            0x00000080
GPMC_CONFIG7_1                            0x00000840

请问这可能是什么问题导致的?谢谢
