I am an FPGA newbie and want to interface a M328P AVR with an A40MX02 FPGA.
The FPGA is already programmed and I would like to check if it is functionally working. I did not see any on board EEPROM to read back memory contents. What would be the best way to test functionality? Would using the JTAG pins ensure a good test? I also saw it has the SDI, SDO, SCLK pins. Can I use these with the MISO, MOSI, SCK pins on my AVR? I already have a board with these pins mapped out so it would be easy for me if I can check for FPGA functionality with these pins.
