when i first got the board and when it was connected by the usb, all the leds blinked and the 7 segment displays cycled from 0 to F. that is it was alright. however, when i downloaded my project, it just gave the same outputs again n again for different sets of inputs.

thats why i put it to program mode instead of run and did AS programming. and erased the .sof file.

and from that time onwards whenever i turn the board on, i just find the 4 0s on the 7 segment displays. no cycling and no blinking of leds.

please help in this regard.
