Quartus can successfully program the device (at least it shows 100% success), but nothing works.
All LEDR are On
CONF_DONE LED is Off.
May I know, which configuration (JTAG Configuration or Internal Configuration) are you doing?
Have you checked the board settings as per device handbook?
Please refer the FPGA Configuration Troubleshooter,
especially link below,
Thank you for the support.
But I believe the board is damaged.
Back to work on Monday, it worked. Then, I thought it could be some problem with my computer.
Today, with same Computer, USB port and project, it stopped working again.
Have you gone through the my previous post? especially configuration issue link?
please do visual check of board especially pins, rather clean it properly, monitor configuration signal voltage levels using standard oscilloscope & try to check implementation of simple D flip flop using JTAG Configuration on same board.
