各位TI大神，
现在遇到一个问题使用东芝TC58NVG1S3HTA00的FLASH，出现以下问题。
UBIFS: start fixing up free space
[ 9.472429] uncorrectable error :

[ 9.762693] 1f07 254464 mtdblock7 (driver?)
nand参数如下：
Organization
x8
Memory cell array 2176 128K 8
Register 2176 8
Page size 2176 bytes
Block size (128K 8K) bytes
感觉是ECC校验问题，之前的flash ecc是1bit的没有问题。
