Yup, definitely need to program the control panel SOF to erase/write the 
flash. The USB Blaster is connected directly to the FPGA (or the FPGA serial 
configuration flash via the PROG switch) and no other devices. When you 
select flash operations in the host control panel software, it relays 
commands to the flash controller IP block in the Control Panel SOF in the 
FPGA. See pg 17 of the DE! user manual for the system architecture.
