Utility will help in signing the firmware.


Limitations
--------------------------------------------

The Sas35/Sas4 firmware has the same Firmware header signatures. Hence, user must be knowing which firmware they are using for the any operations.

Below are the sub image types supported: 

Manufacturing, FlashTable/Bootloader, Signature, FW Status, SBR, Key Update, EROM.

In addition to this, OEMs could have their own image types and it is not possible to always add every new type and display the name. "Unknown" is displayed for this reason. That is the reason the Image type is also displayed in Hex, so that this can be used as a reference to check the product documentation for further details.
