Hi
First I wrote a post because the initialization was crashing, but now I found out it was because the RX line was low. How to initialize the uart if the RX line is low without modifying the hardware. Thing is I have some devices which I power down to save power (gsm and such) and power up only when needed. I also have a uart exposed on the pin header which by default is not connected anywhere. How to make it ignore invalid input states?
