Hi, All
Each time JFFS2 initialized, uboot need to scan the whole flash. This is fairly time consuming.
So EBS(erase block summary) is used to JFFS2 to reduce mounting time. And I believe this can also be used to UBOOT to reduce booting time.
Does UBOOT support this feature? or does any other solution in uboot to reduce JFFS2 scaning time?
Well, I well answer the question myself, after I review the code. U-boot supports this feature around since 2008-12, but it just supports EBS for NOR flash. NAND flash EBS is still not supported yet. I think it's more important for NAND flash, for NAND reading-cycle consumes more time as far as I know. _________________________________________________________________ MSN十年回馈，每位用户可免费获得价值25元的卡巴斯基反病毒软件2010激活码，快来领取！ http://kaba.msn.com.cn/?k=1
