请问为什么AM3352 NAND FLASH UBI文件系统挂载失败？

本帖最后由 一只耳朵怪 于 2018-6-21 11:08 编辑

各位好：
   在NAND FLASH中写入ubi文件系统，内核启动时出现挂载失败。
SDK：ti-processor-sdk-linux-am335x-evm-01.00.00.03-Linux-x86-Install.bin
NAND FLASH（美光：MT29F16G08CBACAWP）参数：
Page size x8: 4320 bytes (4096 + 224 bytes)
– Block size: 256 pages (1024K + 56K bytes)
– Plane size: 2 planes x 1024 blocks per plane
– Device size: 16Gb: 2048 blocks;
32Gb: 4096 blocks
制作ubi文件系统的命令（使用SDK自带的文件系统arago-base-tisdk-image-am335x-evm.tar.gz解压后作为原始的文件系统）：
mkfs.ubifs -F -q -r /opt/ti-processor-sdk-linux-am335x-evm-01.00.00.03/filesystem/target_fs -m 4096 -e 1040384 -c 2047 -o ubifs.img
ubinize -o ubi.img -m 4096 -p 256KiB ubinize.cfg
另外：mtd0为SPI NOR FLASH设备，mtd1设备为NAND FLASH设备
启动信息如下：
