I'm in trouble managing by the fpga section some pins connected to the hps section.

I have two input pin as buttons connected to hps and their status are the input to a component in fpga, they work correctly.

The others 3 output pins, connected to hps as leds, are controlled by a component of the fpga managed by a NIOS routine, they doesn't work.

I manage the leds by a custom component programmed by Avalon Memory Mapped Interface,

its output is the status of single led ( off, on, slow blinking, fast blinking and so on)

They stay permanently in ON state, independently to the the status programmed by software.

in the attach, I have extracted the vhdl code of relative to the connection of the leds (not work) and the keys (working).
