Nios II LCD Driver

Greetings. Quite simply my LCD doesn't "work" with Nios II. It has and does work with Nios I. From the simple "web server" default reference design where the display should show something...

UPDATE:

It appears as though I have a work-around to the LCD errata that was discovered previously in this post re:

The LCD will not operate if the Compact Flash card is plugged in[/b]

I have the LCD now working with the CF card plugged in to the devkit...

Here&#39;s how:

I tied the internal I/O pins: CF_CS_N to Vcc to disable the Compact Flash chip select and set CF_POWER to GND to disable power to the CF interface...

Note that if you want to talk to the CF card, you will have to enable both the CS and CF_POWER signals; thus running into the same problem as before... (or so it seems).

temp fix anyways.
