Hi,Matt 
the  netflash also needs enough memory space ,when I use './netflash -K -r /dev/mtd1 192.168.1.218 jffs2.bin' via tftpserver through ethernet , the netflash requestes  virtual memory  always to store the data and that it's very slow . like my case , the embedded device's memory is very limited . free memory is only 1M ,otherwise the size of jffs2.bin is 3M , it seems it's difficult to netflash too , 
what do you think ? 
Thank you very much 
 
Best Regards

Can netflash upgrade a mounted root partition?

If you don't have the memory to mount the tmp partition in ram, then keep a small second tmp partition in your flash, switch to that, run netflash, and then switch back to the new main parttion.

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
