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
Hi, do you update the preloader on the device? Note that the Pin Mux for the IO is located within the HPS - as such you will need to update the preloader once you set a Loan I/O to the HPS.
