I implemented Zynq+Interconnect+EMC controller on FMC connector, and try to access NOR flash by UART port. e.g. using "mw 0 1" to write data to Flash memory. But it's failed and there is no output on FMC port. I used same way to implement GPIO module and access onboard LED successfully. Would you help?
BTW, there is no design guide or doc of ZedBoard, so I'm using Xilinx Zynq7000 EPP design guide. Is there any significant difference between Zedboard and Xilinx ZC702 board?
