Hi all :

i use dm8168 evm board dvrrdk2,80,

when i boot from nand flash with jffs2 file system, crc error will appear sometimes,

i use nandecc hw 2 before flash uboot to flash and after that i set nandecc hw 0 after flash over ,

do the nandecc setting has effect with crc check for nand flash?

how to set it then?

another questions it seems the bad block increase quickly when flash jffs2 system,

Is jffs2 file system stablity ?
