Thank you ,but I have a trouble ,which is be short of memory . free memory
only has 600K-1.2M , then ,the jffs2 size is 3M (flash size is 4M ,1M as kernel
and redboot),I think it's able to read 64K from web client to write into jfffs
partition very time (total times : 3M/64K), please give me some advise or clue
. Thank you again

Hi,
Many options are possible. If you have the memory:
- load new jfffs2 into RAM,
- mount jffs2 in RAM, using mtd device
- chroot to mtd filesystem in RAM
- unmount flash based jffs2 filesystem
- copy new image to flash
Generally you will have to find a temporary root and unmount the flash root
before copying over to it.

Subject: [uClinux-dev] how to upgrade the jffs2 of root in linux
hi, everyone
I build jffs2 as root file system in my embedded platform with uclinux os , I
also build a web http server(boa) , through httpd server , I can upload a new
jffs2 root file-system into the platform memery ,then I want to use new jfffs
file to re-write jffs2 partition ,because linux is using this partition as its
root file system , if I directly write it into the jffs2 partition ,then linux
will cause crash and errors . anybody know how to do ?
thank you in advance
