Writing into Flash Successfully!

Now, the system returns to Net Port Download Menu.

If you select option 3 in the menu to directly download the program to the SDRAM and run it

there, the downloaded application image cannot survive a reboot because the file is not written

to Flash memory.

 Note:

Upon completion of application image upgrade, the router reboots and checks Boot

ROM version for consistency before starting the VRP software. If the version of the

current extended Boot ROM image segment is not the same as that of the extended

segment to be started, the system automatically updates the Boot ROM image, and

displays “Upgrade Bootrom............! Download completed. Please wait, it needs a

long time###### Writing into Boot ROM Succeeds.” Then, the system continues its

boot process.
