I was considering that, but after much experimentation with the pins I've been able to get it to work better. In the images (and code) you'll see I'm using the A* header for connections. I found that the MISO pin seems to have an issue in the A* header. If I nudge the pin while it's in the A* header the card will initialize immediately (the nudge might temporarily disconnect it?).
If I move the MISO pin in the D* headers it will not need any nudge etc for it to work on the first/second try
Is there something special about the A* headers as compared to the D* header? I'm not sure why it would behave differently.
