Hi all,
My current default partition layout is as follow: 1) u-boot, 2) environment variables 3) kernel, 4) filesystem
I have seen in some implementations, that there is one partition of "data" after the filesystem's partition as follow: 1) u-boot, 2) environment variables 3) kernel, 4) filesystem 5) data(or rest)
What is the purpose of this data partition?
Who reads/writes there (kernel or filesystem(like jffs2)) and *How*? If kernel writes there, then do we have to change kernel configuration? If yes, then what changes are required?
What happens in case, when I don't keep that separate partition of data and only filesystem is given the rest of the flash memory(as I have used)? And How it differs from the partition layout with data as the last partition?
I don't know about this.
Please, help me understand these.
