    Can you program a Cyclone III using active serial mode with a USB-Blaster? I thought you could only program serial configuration devices (EPCSx) using active serial mode.

    Do you have any other application opened on the JTAG interface when you attempt to reprogram the FPGA? Such as a Nios console...
