Cyclone 10 LP Evaluation Kit Pinout issue - Cyclone 10 LP Evaluation Kit Pinout issue Hello, I recently purchased EK-10CL025U256 with Cyclone 10CL025YU256I7G and the problem is probably the documentation. I can't assign the right pins in Quartus Prime Lite. I have two documentations, one attached by the vendor (Mouser) and the other directly from the Design Files I downloaded. I noticed a discrepancy, in this table with pins, and what is in the schematics, but none of these pins are correct. I can't even turn on the LED. Also regarding to this: https://www.intel.com/content/www/us/en/docs/programmable/683580/current/evaluation-board-revisions.html I have revision A2.

Replies: Re: Cyclone 10 LP Evaluation Kit Pinout issue Maybe my program is a problem or a upload to the board even if it's successful. I've tried statically turn on the LED, but nothings change. After a few minutes D6, D7, D8, and D9 automatically starts blinking. This state is from the beginning and nothings changing it. library IEEE; use IEEE.STD_LOGIC_1164.ALL; entity ONE_LED_BLINK is Port ( led : out STD_LOGIC ); end ONE_LED_BLINK; architecture Behavioral of ONE_LED_BLINK is begin led <= '1'; end Behavioral; Replies: Re: Cyclone 10 LP Evaluation Kit Pinout issue D6, D7, D8, and D9 are the board references on the silkscreen, not device pin numbers, so L14, K15, J14, J13 are correct. As for why it looks like a power pin is showing up at location L14, check to see if that is perhaps a dual function pin.

But also in Design files pins for those User LED's have diff pinout I know that in PDF pins have the same description as on the top of the board and description in this schematics refers to Cyclon pinout. The case is none of them could be used in Quartus, because those pins have another assignment as I know. I have tried every of those pins and none of them works to blink User LED. F.e. pins D6, D7, D8, D9 in PDF are L14, K15, J14, J13 in schematics.
