I have a RPI3 and was doing a loopback test of SPI.
https://www.raspberrypi.org/documentati ... /README.md

I am able to send/receive data, but the waveform doesn't look good. Is there something wrong with my PI or do all PIs have the same "sad" looking waveform.

Perhaps your test set up is faulty.
