kangear注：此文描述了u-boot中的分区
开启调试
修改wyh2440.h
/*
?*debug enable
?*/
#define DEBUG
#define CONFIG_NAND_DEBUG
修改s3c2440_nand.c
+#if !defined(CONFIG_NAND_DEBUG)
+#undef debug
+#define debug(fmt,args...)
+#endif
+#define S3C2440_ADDR_NALE 0x08
+#define S3C2440_ADDR_NCLE 0x0c
修改 s3c2440_hwcontrol 函数
static void s3c2440_hwcontrol(struct mtd_info *mtd,int cmd,unsigned int ctrl)
{
?struct nand_chip *chip = mtd->priv;
?struct s3c2440_nand *nand = s3c2440_get_base_nand();
?debug("hwcontrol(): 0x%02x 0x%02xn",cmd,ctrl);
?if (ctrl & NAND_CTRL_CHANGE) {
??ulong IO_ADDR_W = (ulong)nand;
??if (!(ctrl & NAND_CLE))
???IO_ADDR_W |= S3C2440_ADDR_NCLE;
??if (!(ctrl & NAND_ALE))
???IO_ADDR_W |= S3C2440_ADDR_NALE;
??????????????? if(cmd == NAND_CMD_NONE)
??????????????????????? IO_ADDR_W = (ulong)&nand->nfdata;
??chip->IO_ADDR_W = (void *)IO_ADDR_W;
/*
??if (ctrl & NAND_NCE)
???writel(readl(&nand->nfconf) & ~S3C2440_NFCONF_nFCE,
????????? &nand->nfconf);
??else
???writel(readl(&nand->nfconf) | S3C2440_NFCONF_nFCE,
????????? &nand->nfconf);
*/
?}
?if (cmd != NAND_CMD_NONE)
??writeb(cmd,chip->IO_ADDR_W);
}
没完没了的hwcontrol() dev_ready打印信息
还是取消nand 的debug信息吧
