关于AM335X文件系统制作完成后ubi.img太大以及ubi无法挂载（cannot open "ubi0:rootfs", error -19）

Other Parts Discussed in Thread: AM3352, TPS65910

大家好，我制作文件系统使用的是arago-base-tisdk-image-am335x-evm.tar.xz，NAND 是256M的MT29F2G08ABAEAWP，将其解压到rootfs/filesystem目录后用如下指令制作：

mk_ubi.sh：

echo "start to create ubi ... ..."
echo "make ubifs.img ... ..."
mkfs.ubifs -r filesystem/ -F -o ubifs.img -m 2048 -e 126976 -c 2047
echo "make ubi.img ... ..."
#ubinize -o ubi.img -m 2048 -p 128KiB -s 512 -O 2048 ubinize.cfg
ubinize -o ubi.img -m 2048 -p 128KiB ubinize.cfg
echo "create over!!!"

ubinize.cfg内容如下：

[ubifs]
mode=ubi
image=ubifs.img
vol_id=0
vol_size=200MiB
vol_type=dynamic
vol_name=rootfs
vol_flags=autoresize

但是制作出来的ubi.img有120MByte，什么原因？是我操作过程不对么？

再有是启动内核在加载ubi的时候出现了如下错误，请问什么原因：

请问您是按照哪个文档做的？

周工你好，基本上是按照你的这个文档http://www.deyisupport.com/question_answer/dsp_arm/sitara_arm/f/25/t/59921.aspx做的，因为之前在其他版本（SDK-01.00.03）上也做过，貌似都能正常挂载，现在在SDK-03.02.05上重新做好像就不行了，我UBoot按照你的文档增加了宏定义，内核也按照你的文档配置了对UBI的支持（am335x_evm_defconfig默认就支持的）！设备树文件或者内核是否还需要进行其他配置？

我的uboot环境变量如下：
