Description: The upgrade method of Flash partition, ie., method by which new files can be downloaded into the partition. FLH stands for Flash Load Helper, a feature provided on run-from-Flash systems for upgrading Flash. This feature uses the bootstrap code in ROMs to help in automatic download. This object should be retrieved if the partition status is runFromFlash(2). If the partition status is readOnly(1), the upgrade method would depend on the reason for the readOnly status. For eg., it may simply be a matter of installing the programming jumper, or it may require execution of a later version of software that supports the Flash chips.

unknown(1) - the current system image does not know how Flash can be programmed. A possible method would be to reload the ROM image and perform the upgrade manually. rxbootFLH(2) - the Flash Load Helper is available to download files to Flash. A copy-to-flash command can be used and this system image will automatically reload the Rxboot image in ROM and direct it to carry out the download request. direct(3) - will be done directly by this image.
