@zack What are the default configuration of gateware?
if i program default gatware bit file in FPGA through flash memory what will be the output in spectrum analyzer?. I don’t want to configure limesdr through GUI i want to play with gateware but first of all i want to test default gateware output if it shows some output in spectrum analyzer then i will start making changes in the gateware
As I said before, all the configuration is uploaded from the host PC. Gateware itself does nothing in this respect. But you may re-write the gateware and implement this functinality.
