fpga is getting heated unusually

It doesn't sound like your board is particularly usable as is. So, I'm not sure what you've got to loose.

However, one final thing to try before reprogramming it. Do this to establish if it is already in it's factory state. This isn't foolproof but it will tell you whether the FPGA is booting it's factory image.

Run the "Board Test System" software (runs on your PC) that came with the kit. Download the 'Kit installation' from board's homepage on Altera's site if you can find it.

This software allows you to test certain FPGA interfaces. If it works from power up then the FPGA is being configured with the default factory image and there is little or no point in reprogramming the board's FLASH.

Get familiar with the Board Test System software without the hardware on. It'll complain it can't find the board - fine. I suggest you find the 'Toggle All LEDs' button. Exit the software.

Then:

1) Power up the board.

2) Run the software.

3) Try toggling the LEDs.

4) Power off the board.

I think you can do all that in 3-4 seconds.

If the LEDs (LED1-LED4) toggle when you push the button, then the FPGA is (almost certainly) being configured with the factory default image. So, you need not reprogram the FLASH.

If they don't toggle the FLASH has probably been changed and I suggest you do try to reprogram the FLASH.

Like I say - the board doesn't sound like it's of much use at the minute. What have you to loose?
