Reduce your complexity.
Build an SOPC system with a JTAG-to-Avalon-MM master and a PIO component and an LCD component. Connect the PIO component to LEDs on your board.
Then use SystemConsole to perform read/write access to your LEDs. When you can blink your LEDs, you know that you have SystemConsole working.
Then perform read/write accesses to the LCD.
The LCD needs to be initialized before you will see characters.
