Hi Abeer,
These symbols are all defined within our example flash programmer driver code - you would need to add (meaningful) definitions of all of the required symbols within your own code.
I recommend starting by looking at the examples, such as the BF548 EZ-KIT Lite Flash Programmer Drivers for parallel (burst) and serial flash, which are in the VisualDSP++ installation directory at "...\Blackfin\Examples\ADSP-BF548 EZ-KIT Lite\Flash Programmer\".
Regards,
Craig.
