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
Hi, all
If I wish to support uImage in jffs2 FS in NAND flash, how many size will be
used for JFFS2 FS itself, such as wearing level, GC, JFFS2 INODE header?
For example, NAND fash size is 32M and uImage is 8M including application and
kernel.
Thanks
Leon
Thank you, Scott :)

Hi, all
I'm a little confused on NAND read operation.
According to NAND character, NAND flash is read page by page, which mean's once
you read, at least you should read data with page size (such as 512Bytes)
But the nand_read_byte() is implemented as following: static u_char
nand_read_byte(s
