[uClinux-dev] how to upgrade the jffs2 of root in linux

[Crane, Matthew]

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.
 
Matt

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 
 
                                   advan
