GPIO LED from MIO is not working in self designed board

Former Member
Former Member over 8 years ago

Hi there,
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?
Thanks
Shruti

    This Adam Taylor's MicroZed Chronicles chapter details using the MicroZed PS GPIO to drive the LED:

    In the MicroZed design MIO48 is connected to the USB-UART. If you are using the MicroZed board definition files to start your hardware design that could be your issue.
