I have configured the FPGA. The programmer board contains a DAC904 (14 bits 160MHz DAC) and ADS831E (8 bits 80MHz ADC) for testing purposes. I have generated some waveforms using the DAC and also piped the ADC input out the DAC. It might make a nice scope/function generator demo. I will be doing a real ADC/DAC board later with 2x LTC2299 and a MAX5893.
The only problem I am having so far is figuring out how to get ld to put instructions and data in seperate files so I can use instruction/data SRAM. It runs much faster that way, but it is not possible to fetch data from instruction SRAM. Hopefully I will get that one resolved with reading more man pages.
I look forward to getting this thing interfaced to GNUradio. Any questions are welcome.
