Issue Description

The conventional upgrade method is transfer the package to Flash, and then specifies the next starting files, restarts the device at last. Due to majority of the current packages are more than 32M, and the largest space of the Flash is only 64M, cannot accommodate two software packages, so have to delete the original software package of the flash before upgrading, and deleting files is a very time-consuming task, the greater the file, the time to delete is more longer, how can accelerate the speed of deleting files and shorten the time of upgrade?

Handling Process

Before the upgrading, upload the file of the Flash which needs to be backup to computer, and then restart your device to enter the Bootrom menu, in the hidden menu formatting the Flash, and then upload package, because the formatting speed is faster than the speed deleting the software package, through this can save upgrading time, speed up the upgrading.

Due to the restriction of Flash erasable mechanism, deleting the data block operation is relatively slow, the greater the file is, the deleting time is longer, and the formatting operation to the entire Flash is very fast, it is quicker several times than completely deleting a file which is dozens of M. 


Through the format Flash mode to upgrade usually can save more than 10 minutes time at least.
