(PicoZed SDR + breakout carrier + kernel v4.6.0)
Every time I boot up the platform, when kernel is loading and until I execute my program, some signal appears at the TX output:
Why? How to solve it? I suspect it could be the oscilloscope application auto-starting up, maybe? (PicoZed doesnt allow to connect a monitor nor I cant see any oscilloscope related process using htop), if so.. where's the script that autoexecutes it?
And also: when I want to finish my custom program with CTRL+C, I've got a handler that destroys the iio_context, iio_buffers, etc. but when they are destroyed, the radio starts transmitting some undesired signal. I solved this configuring the TX attenuation ("out_voltage0_hardwaregain") to its maximum before exiting the program, but it does not look like the right way to do it. Any suggestion?Regards, Leroy.
