L476 Problems getting the FMC working with SSD1963

We are having problems trying to make a 320x240 LCD Color Display working on the L476 FMC Peripheral.  The LCD uses the SSD1963 chipset.  We have hooked the SSD1963 up to the FMC like an 8080 SRAM device using the parallel 16-bit data bus and 1 Data Address bit to communicate.  For some reason, we can't seem to get the FMC to duplicate the waveforms on the SSD1963 specification.....A0 address line will not stay asserted during data write, and the CS line is way off from any Data Access signal.  Could someone point us to what is going on?  BTW, we are using the STMCubeMX HAL drivers for our project.

 

Let me also mention that we would be glad to pay someone who has gotten the FMC working with the SSD1963 as well.  Just E-mail me at rasmusjc@gmail.com, and I'll forward you to our manager.

 

Thanks,
