The system I am developing does only do little amount of disk writing so I have been considering to using two partitions: a read only boot partition containing the entire linux root and boot dir and one writeable for the dynamic application files. But from the mail archive I can see that the two partition solution does not solve the problem if NFTL is involved as the wear levelling will be done across partition boundaries, so the writeable partition may corrupt the readonly. Another solution would be to run jffs2 on the DOC. But the drivers that comes with the kernel I use (2.4.18) does not support this. Are there any version of the mtd drivers that currently support this ? If no, do there exist a patch that makes the DOC driver compatible with jffs2 or can anybody supply me with description of the necessary modifications. Any advice are appreciated. Thanks, Poul Lund Jørgensen
