We have designed a Zynq7030 based board, similar to microzed board with some additional peripherals. The LED for PS GPIO is connected to MIO48 in our board whereas it is connected to MIO47 in Microzed board. The circuit is exactly same as given in Microzed schematics. Our LED is permanently glowing. We are not able to find the reason. We have not got any reference design for GPIO for Microzed board. Could anyone please explain the reason or share Microzed refrence design for PS GPIO peripheral test?
