New Contributorconf_done LED blinks once
Hi,
I'm a FPGA newbie with a DE10-nano board and have a problem with it.
I use the USB blaster.
When I supply power on my board,
3.3V Power LED, conf_done LED go HIGH, and USER LED blinks.
At first, LED 0:7 also blink sequentially.
It's a simple test code and I think my code doesn't have any problem.
The four input pins are assigned to SW 0:3, and the eight output pins are assigned to LED 0:7.
So if I turn up each switch, two leds go HIGH.
Like this.
It works well, but after several seconds (around 18s ~ 20s) conf_done LED (LED10) goes LOW and quickly goes HIGH. (This takes less than 1 second.) So the loaded data is gone. Everything got reset. So led 0:7 blink sequentially again.
I did nothing. The power goes to the board constantly.
What is the problem? What should I do?
Waiting your help.
Thank you.
Do you have an SD card installed? If so, the HPS is probably booting and then reconfiguring the FPGA back to its default design.
