GPMC与FPGA通讯同步模式写成功,读不到数据

技术大神们,请帮忙看下,

在Evm3354上开发GPMC与FPGA通讯的驱动,7个config配置如下:

#define STNOR_GPMC_CONFIG1 0x28601000
#define STNOR_GPMC_CONFIG2 0x00011001
#define STNOR_GPMC_CONFIG3 0x00020201
#define STNOR_GPMC_CONFIG4 0x08031003
#define STNOR_GPMC_CONFIG5 0x000f1111
#define STNOR_GPMC_CONFIG6 0x0f030080

其中config7 = 0x00000f4d

采用同步读写模式,同步写已成功,读不能出数据,请问有谁配置成功,能否给个参考配置
