再开一贴 V851 使用SPINAND ubifs ，始终没有生成ubiblock块，无法挂载根文件系统

[liuqiang]

使用以下命令，以及配置ubi.cfg
ubinize.cfg放在
target\allwinner\generic\image

make -j1 BLOCKSIZE=131072 PAGESIZE=2048 SUBPAGESIZE=2048 UBIFS_OPTS=' -F -m 2048 -e 131072 -c 736 ' _UBI_OPTS=' -m 2048 -p 131072 -O 2048 -s 2048 '

烧录启动后

使用是mtdblock，没有ubiblock，

提示：
“内核关闭readonly-ubi块的配置，让系统可以顺利创建出可读可写的ubiblock”

请问大家这个配置在哪里关掉

内核没有配置ubi，没有挂载ubi功能

我在發生內核恐慌的同時也遇到了類似的問題，這可能是 ?

@liuqiang 关闭readonly 是在Enable UBI下面
