TI中文支持网本人用CPU是DM365，采用的是368的方案
之前文件系统是通过nfs挂在服务器上启动，可正常启动。现在我把文件系统ubifs烧到flash上启动，同时修改了启动环境变量：
setenv bootargs 'mem=48M console=ttyS1,115200n8 noinitrd ip=dhcp rw ubi.mtd=3,2048 rootfstype=ubifs root=ubi0:rootfs cmemk.phys_start=0x83000000 cmemk.phys_end=0x88000000 cmemk.phys_start_1=0x00001000 cmemk.phys_end_1=0x00008000 cmemk.pools_1=1×28672 cmemk.allowOverlap=1 cmemk.useHeapIfPoolUnavailable=1 nohz=off highres=off clocksource=acpi_pm lpj=1077248 eth=$(ethaddr) quiet'
启动错误：

ubifs文件系统我是在ipnc_rdkZ直接make ubifs生成镜像，是否因为配置不对，或者那些地方需要修改的？
Rules.make修改如下：

求大神指点，万分感谢！
Eason Wang：
1. 确认你的Kernel和文件系统来自于同一套RDK
2. 以前是否有过能够用的ubifs？回溯一下看看，确定bootargs之类配置没有问题。
3. 重新烧写整个nand，先用nand scrub指令清除nand上的数据。
4. 请问试了几个硬件，是否每个硬件上一样的问题？

你好：
感谢您的回复！
1、kernel和文件系统是用同一套RDK
2、之前是用NFS的方式挂服务器上启动，现在想烧到nand flash上用ubifs启动，bootargs参数配置是根据UserGuide_IPNC_RDK_DM36x.pdf手册，应该是没错。
setenv bootargs 'mem=48M console=ttyS1,115200n8 noinitrd ip=dhcp rw ubi.mtd=3,2048 rootfstype=ubifs root=ubi0:rootfs cmemk.phys_start=0x83000000 cmemk.phys_end=0x88000000 cmemk.phys_start_1=0x00001000 cmemk.phys_end_1=0x00008000 cmemk.pools_1=1×28672 cmemk.allowOverlap=1 cmemk.useHeapIfPoolUnavailable=1 nohz=off highres=off clocksource=acpi_pm lpj=1077248 eth=$(ethaddr) quiet'
3、已经试过把整个flash擦除掉，可是还是一样的问题。
4、我手上只有一个硬件，我想nfs能够启动，硬件方面应该没有问题吧。
编译成ubsfs镜像是不是只需要修改Rules.make?？
现在我如果插着网线，还能启动到文件系统，可是报一大堆错误：
