AM335X Cannot open root device "ubi0:rootfs问题

我们烧写AM335X SDK6.0 的提供的arago-base-tisdk-image-am335x-evm.ubi文件系统，跳线到nand flash启动，那么U-BOOT 的bootargs应该如何配置呢？sdk里文档说root=ubi0:<VOLUME NAME> ubi.mtd=<PARTITION_ID>,YYYY rw 。按照这个去配置了，但内核启动失败信息如下,

VFS: Cannot open root device "ubi0:rootfs" or unknown-block(0,0)
[ 11.349212] Please append a correct "root=" boot option; here are the available partitionsVFS: Cannot open root device "ubi0:rootfs" or unknown-block(0,0)
 
arago-base-tisdk-image-am335x-evm.ubi的:<VOLUME NAME>是rootfs吗？？

你烧写的文件系统是ubifs的吗？
