Hello to everyone,
I've been using the DE1-cycloneV for two years at university. I bought one for me now but there is something which worries me: the board makes constant noises i didn't hear before. For example, at the startup flashing routine it periodically makes these noises whenever 7-segments/leds blink. Anyone has an idea on what could it be? Thanks.Link Copied

Hi,
May be because of the program which is loaded by flash / power issues. 1.Erases the flash memory and load new program check. 2.Check the hardware and setup side(power circuitry components). Best Regards, Anand Raj Shankar (This message was posted on behalf of Intel Corporation)- Mark as New

I did it (a single led single switch) but a noise (less than before) is still there. However when I switch off/on all the noises come with the flashing startup. It's like the noise is bounded to the number of elements being used (all the leds/segments at the start). 2.I'm using the box cables plus an adapter for us/eu (it cannot be that, it's a power plug!)
