I am trying to get Xilinx microblaze to do the simple operation like output = input, I don't want to include UART port or any other similar port to it at this point. (Later on I want it to work with an external RAM)
This is how I tried to do it:
1- In ISE I did "project\new source" and chose "Embedded systems"
2- double clicked on it and opened Xilinx Platform Studio" tool.
3- In XPS in "IP catalog" double clicked on "AXI General Purpose IO" and defined two (one input, one output) ports and called them DataIn and DataOut, and I made them external ports
4- Then "Export Hardware Design to SDK" open SDK tool, where I first did "File\new\board support package" and created "standalone_bsp_0"
5- Then "File\New\Application project" and select "use existing standalone_bsp_0" and "language C" and created a "Helloworld.c"
6. This is my code:
7- I built the elf file and took it to ISE, I made a testbench in ISE and instantiated the microblaze, and apply CLK_P, CLK_N, RESET and DataIn, and DataOut, but the code doesn't work and dataOut stays 0. I think in my code I don't have access to my I/O ports (dataIn, and dataOut). I tried to use XIOModule instead of xgpio but SDK doesn't recognize #include "xiomodule.h" it gives me the error: Unresolved inclusion: "xiomodule.h"
What am I missing here?
