HPS GPIO's ouputs stuck in high impedence?

Ravi,

I am sorry you need to start with the basics... it involves creating a simple system with your cyclone v soc process (or other processor of your board) with Qsys within quartus, generate the design and create a top level design in either Verilog or VHDL hardware languages. You can then get to grips with it all.

Please if you require further help follow the tutorials within this website. Although might not be available for your board you will be able to follow the process accordingly.
