All,

Our system requires the software upgrade feature (for both application and
kernel) during the user space application is running.  I don't know how to
go about it in Linux environment.  

If I can get an image (from USB flash) and copy it to the RAM while the
system running and some how reboot the system in U-boot (without reset the
RAM).  From there I can run the uboot script to copy the image from RAM to
flash.  Would this work? Is there any better way to do this?

Thanks

HN
