I am seeing strange behavior when I try to toggle a GPIO output on a MIO pin. The pin will toggle while in a debug session, but when the Zynq is configured by QSPI flash there is no pin response. The flash was programmed both by Impact and also through the SDK with the same result.
I configured the GPIO over MIO through Vivado and am using this blog post as a guide: http://forums.xilinx.com/t5/Xcell-Daily-Blog/Driving-the-Zynq-SoC-s-GPIO-Adam-Taylor-s-MicroZed-Chronicles/ba-p/389611
I am using MIO pin 12.
Any ideas?
