Hello,
Once again the FMC230 reference design is perfectly able to configure the DAC, so the SPI module in the reference design is operating just fine, please refer to the reference, which is delivered as source code and with documentation.
As explained already, StellarIP will not generate IP core but use IP core to generate a firmware, which in this case contains the FMC230 star.
You could decide to also ask 4DSP to provide you with the reference design you need, a one channel DAC on ML605 LPC. If this is a path you are willing to take, let me know and I will get one of our sales engineer to get in touch with you.
Best Regards,
Arnaud
