Blinking LED pin on HPS using FPGA logic?

Hi, 

 

I am trying to blink a LED which is connected to the HPS from a button connected on the FPGA. I have built the Qsys design and Loaned the I/O desired pins to the top level entity, then by setting the loan_io_oe[x] to 1 will let the connection be as an output and could be controlled by the loan_io_out[x], however I get no response. When doing the opposite procedure it works!! by letting a button connected to HPS to control a LED connected to FPGA. 

 

So what could be the problem here? I have been stuck for days on it. 

 

Thanks, 

Yazen
