我把demo上的NAND驱动位宽从16位改到8位,GPCM好像不工作了,ID都读不出来了,哪位知道为什么?其他的都没有任何改动。

多谢,搞定了,把NAND的ALE/CLE/DATA从UINT16改成UINT8就可以了!!!
#define NANDFLASH_CLE *( volatile Uint8* )( NANDFLASH_BASE + 0x7C ) // change to uint8
#define NANDFLASH_ALE *( volatile Uint8* )( NANDFLASH_BASE + 0x80 ) // change to uint8
#define NANDFLASH_DATA *( volatile Uint8* )( NANDFLASH_BASE + 0x84 ) // change to uint8
