My NEEK (3C25) is resetting

Hi,

I found a NEEK board (3C25) which is not in use for a long time. As i am trying to play with linux, this is a very good platform. This board is getting reset continuously with any sof file provided with examples except standard. I restored all flash and SD card to factory restore, which did not solve the problem. when I hold the reset button, fpga configures from flash. nothing happens on lcd.

If I load sof from stabadrd exaple, i can run hello world (Iinfine loop) program without a problem.

Is my board gone? or Is it a Power problem? Any ideas?
