"Fail to Connect your development board"-Cyclone III Starter Kit

Honored Contributor II

Dear All, 


Anyone can help me? 


After I install the USB blaster driver, My Cyclone III FPGA Starter Kit worked at the first time, but can not be detected afterwards after I disconnceted the power and connect the power again. 


It says ""Fail to Connect your development board" using the starter kit controal panel. 


I re-install the driver again and again , still failed, I also used Windows device manager to delete the USB Blaster, and reinstall again, still does't work anymore. 


What should I do? It is Winodows 7, a notebook. 


Thank you very much!

Was it due to I erase the flash memory last time?
