I am using LMS7002 and STREAM board. I used USB blaster to develop in Quartus after I connected USB to LMS7002 and STREAM board respectively, and updated firmware with FX3 using cypress suite. Suddenly, the STREAM board did not connect to the computer, even though I used a different cable. What should I do??
