[Solved] Broken Mimas V2?

After some initial success with simple examples with push buttons and LEDs I wanted to move on to VGA.
My first attempt caused the monitor to display an "out of frequency range" message. Since then NOTHING works. A trivial Push button & LED example appears to download OK, but does not function.

--------------------------------------------------------------
//Simple_LED file

`timescale 1ns / 1ps

module Simple_LED(A, B);
input wire A;
output wire B;
assign B = !A;
endmodule
--------------------------------------------------------------
# User Constraint File for NOT gate implementation on Mimas V2

# Onboard LEDs
NET "B" LOC = T18;

# Push Button Switches.
# Internal pull-ups need to be enabled since
# there is no pull-up resistor available on board
NET "A" PULLUP;

NET "A" LOC = M16;

The Power LED is on and there is power at various places on the board.

I cannot see any obvious damage and there seems not to be a fuse anywhere.
Have I bricked my Mimas V2?

 

Hello Tom,

thanks for the quick response. I have loaded the example file into my Mimas...
and it all works as expected. A relief that I had not damaged the board so soon.

My actual problem turned out to be with the project configuration.
After downloading and trying various examples, copying files etc I had propagated an
error into all the following projects.

In project Design Properties I had selected an incorrect device.
Among other things this resulted in the downloaded bin file to be the wrong size.
So no wonder it did not work.

Thanks again
Martyn
