移植内核，启动时分区显示不一致，求助？？？
我移植的内核是2.6.27uboo是2011.12平台是at91rm9200我的疑惑是？为什么我这里是三个分区
Creating 3 MTD partitions on "NOR flash on AT91RM9200":
0x00000000-0x00050000 : "u-boot"
0x00050000-0x00190000 : "Kernel"
0x00190000-0x003f0000 : "rootfs"
后边怎么成了5个分区
Please append a correct "root=" boot option; here are the available partitions:
1f00 2048 mtdblock0 (driver?)
1f01 4096 mtdblock1 (driver?)
1f02 320 mtdblock2 (driver?)
1f03 1280 mtdblock3 (driver?)
1f04 2432 mtdblock4 (driver?)
下面是启动信息：

谁知道的话？加一下我的QQ？手机在线等？我的qq：858846479有点事请假，纠结了好几天了？
你可以修改 uboot分区，在include/configs下的配置文件中，也可以修改内核分区信息，一般在arch/arm/mach-xxx下，也可以直接用uboot的命令烧写文件系统到你内核分区信息中文件系统的位置 你可以用ＵＢＯＯＴ命令烧写，那样就与ｕｂｏｏｔ分区没关系了
