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

    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.
