Hi all,
I'm wondering why linux and u-boot are seeing different files when I use a jjfs2 image on my nand flash.
This is what I've done. I partitioned my nand flash with 3 partitions (u-boot, jffs2, user) Then I flashed the jffs2 image with nand write.jffs2 booted the uImage from my jffs2 with fsload That all worked fine (although fsload is extreamly slow) and I can use my linux. Then I created a new file in my root. A "ls" from linux displays that file. With a "ls" from u-boot the file is not visible... So what went wrong? Who is cheating on me?
Some additional info: I use the mtd stuff from mtd-snapshot-20050524.tar.bz2 with a 2.6.11 kernel. I executed patchkernel.sh from the mtd package. I created a jffs2 image with mkfs.jffs2 -e 16384 -qnd my_rootfs -o jffs2.img Then I flashed the image with nand write.jffs2 (or from linux with nandwrite). A "ls" shows me the contents of the image as expected.

Then I boot linux and mount my jffs2 partiton. I deleted the uImage from it. A "ls" from linux shows me that it is deleted. Then I rebooted and did a "ls" from u-boot.

The uImage is still there. And "bin, dev, etc, initrd, lib" are listed twice.

What I'm doing wrong?
