Hi,
I have couple of doubts regarding jffs2 filesystem.
1. I've found instances of writing mtd partitions with dd (like dd
if=rootfs.jffs2 of=/dev/mtd...) and another method is to use flash_erase
/dev/mtd.. and then copying rootfs.jffs2 to /dev/mtd.. using cp command
followed by sync. What is the difference between these two?.
2. How jffs2 works? I mean if my root partition is jffs2, if I access some
files, is it accessed real-time from the flash device?
OR
Does the kernel uncompress the jffs2 partition and stores it in memory during
boot and access it from there when a read request comes?
TIA,
Arun
