I am using Vivado 2016 which only support Zedboard target. Already set JP1,2,3 to SD mode. I can not boot any thing from uSD card, seem to be interface uSD is not detected. I search many topics then they said need to set CD and MIO 0 pin to 0 when durring SD boot mode, but it is fixed when design in Vivado. So anyone can help me how to set CD or MIO 0 pin to 0 or other solutions. Thanks
