Hello, I have a board that always outputs a high signal on all D pins. I tried to completely erase the firmware, but even without the firmware loaded, it still outputs a high signal on all pins. The LED on the board is lit.

In your opinion, what could be the malfunctions? Could it be that the chip itself is broken?
