We'd like to format linux kernel and rootfs image partitions (and the others) with jffs2, because the two images may be replaced with newer ones while Linux is running.

It is not a problem to replace the linux image while it is running, because Linux runs from RAM. You can always replace the Linux image.

A first question is: Is it possible to boot (bootm command) the images stored in partitions formatted using jffs2?

U-boot can read JFFS2 partitions, but as I said, this should not be necessary if your goal is only to replace the kernel images. And u-boot does not need to understand the rootfs, too.

Hi all,

I work with Fabio Ubaldi. The problem is this: the new linux kernel image is send to system from a remote site and the system has to update the image automatically. Our ideas was this: after the system had mounted the jffs2 linux kernel partition, it copy the new image in /mnt/kernel (jffs2 linux kernel partition) and after that the system is rebooted. To perform this U-Boot must be able to boot a linux kernel image from a jffs2 partition. I hope that the problem is now more clear.

Thanks. Marco Stornelli
