What would be interesting would be doing this with a Cubietruck because that has more flash memory. Part of the problem is that there are a lot of bits flying around - small, small ARM boards without good FPGA bolted on are not so good at this. Now if the Parallella had really taken off :( All the best, AndyC G0EVX _______________________________________________ HackRF-dev mailing list [email protected] https://pairlist9.pair.net/mailman/listinfo/hackrf-dev
