Hi!

Last days I read a lot about embedded linux and flash devices:

Ipronto is working with jffs2 - a file system for devices with flash rom instead of hdd.

The memory is partitioned into 7 partitions:

0 - boot image
1- linux kernel
2 - filesystem (I think this is what is called "root file system")
3 - intent
4 - storage
5 - epg
6 - icf

what i found out while analysing the update script: Everything is ok as long as partition 0 is untouched. If you modify the kernel image or the file system the worst what can happen is ipronto will crash during boot sequence.

In case of crashing linux kernel just run the original update process and the firmware is restored. After that the ipronto should work fine again.

But NEVER touche partition 0!! If this partition is damaged, Ipronto will not boot and there is nearly nothing you can to by yourself to restore the system.

p.s.: Today i downloaded the vmware player and a suse machine where i will try to mount the jffs2 image. I hope it works.
