Shlomi, We do not have any Linux API we can offer. The ADS54J20EVM has no way to bring in an external interface for the SPI signals. You will have to use the FTDI device as is. On the DAC EVM, there are resistors you can remove and try to use the available pads to connect a harness to another source or your FPGA to drive these signals. That is the best I can think of.
