dm8168 uboot nand问题

板子是别人的，没有其uboot代码，自带uboot的nand检测和操作都正常。

我是通过

tftp 0x81000000 u-boot_dvr.bin

go 0x81000000

启动自己编译的uboot。

uboot是DVRRDK_04.00.00.03上面的，nand是MT29F2G16ABAEAWP

什么都不改，启动后出现：

NAND info: HW ECC BCH8 Selected
NAND device: Manufacturer ID: 0x2c, Chip ID: 0xca (Micron NAND 256MiB 3,3V 16-bit)
NAND bus width 8 instead 16 bit
No NAND device found!!!
0 MiB
MMC: OMAP SD/MMC: 0
*** Warning – bad CRC or NAND, using default environment

nand无法读写。

然后在uboot中代码里面强制改成16位（nand_get_flash_type函数中注释掉下面一句话）

//busw = (extid & 0x01) ? NAND_BUSWIDTH_16 : 0;

能检测到了。

但是读写的时候出现

UBOOT # nand read 0x81000000 0x00280000 0x300000

NAND read: device 0 offset 0x280000, size 0x300000

3145728 bytes read: OK

结果读进内存的内核是错的，无法启动，提示wrong format..

user1369122：

你用的是DVRRDK的哪个版本？

你好：

uboot是DVRRDK_04.00.00.03中的

你好，2.8你指的是mcfw 2.8版本么？

下面是自带uboot的打印：

还有奇怪的是，我运行自己编译的uboot命令提示符竟然是U-BOOT

大白他弟：

回复 user1369122:

你好，问题解决了。我修改顶层Rule.make中编译选项DVR_RDK_BOARD_TYPE

改为： DVR_RDK_BOARD_TYPE := DM816X_TI_EVM

然后就一切正常了。但我还是不太懂，请问在dvr_rdk4.0的包子中这两个选项对uboot的nand驱动有啥影响？
