Current CAS is ISTAP version,we need flash CAS firmware to continue.

Tips:

Why do we need to read cas flash and eeprom before continue?

It will be not avialable to use if reflash the firmware if fails.So we strongly suggest if you have VVDI Prog,please use VVDI Prog read the flash and eeprom data,save it. If fails,we can use the data to restore.
