关于emif16 nor flash bootloader



你好:

 现在我在调试C6678的emif16 nor flash bootloader时出现了一些问题,还麻烦各位专家帮忙解答一下,谢谢了!

 我们使用的BOOT方式是EMIF16 NOR FLASH boot,NOR FLASH连接在CE2上,连接仿真器查看寄存器DEVSTAT(0x02620020)的值为0xDBF1,BOOTCOMPLETE(0x026013c)的值为0x01。说明BOOT方式是设置为EMIF16 BOOT的,RBL完成后PC指针是指向的0x70000000空间的,但是仍然无法读取NOR FLASH中的数据,读取的值全部为0。查看EMIF16配置寄存器区域(0x20c00000)看见这些寄存器是初始化了的。
