7 years ago I tried to reproduce a working serial on the May "Raspbian" and also did further tests on a PIXEL version. If I use Node-red and access the serial on pins 8/10 everything works ok. (Using Node-Red serial module) The second I run a sketch that tries to use the serial.println.... it stops working, even if i kill the arduino sketch and try the node-red again, it still does not work. The sketch does not write to the serial ttl pins. If i look in the run/sketch log it shows the text that was supposed to go out the serial.
If I run the resulting bin file directly from a command prompt on the PI it outputs the serial to the console, not the ttyAMA... port.
I have to reboot to get the node-red tty access working again, simply stopping the sketch is not enough
I also tried this on the earlier version of Raspbian again, I must have done something off the first time around and made it work, but following the instructions on a new PI2 and New imaged SD card, it does the same thing as with the PIXEL version of raspbian. I do not recall what I did the first time but the raspbian image had other installs tried to get an arduino sketch to run prior to using this version so it is possible one of them had changed something. Using a brand new SD image this process fails with the serial, and as Pete Scargill has reported, there are other stability issues needing to be addressed.
I hope you can fix this as I was hoping to use this version of RasPiArduino in my training videos on my youtube channel.

Tried the RasPiArduino on a Pixel version of Raspbian and it fails every time I try to use the ttl serial (Pins 8,10). I2C and Digital IO still seems to be ok.
I reverted back to Raspbian from about may 2016 and everything worked great so it looks like the RPI folks have changed something.
