I could not get the arduino pro mini to work with just comport no matter how i tried, so i installed "Pduino" and after installing
pd-mapping, pd-pure, pd-moocow [pdstring] i got it to work
...and connect Tx to Rx and Rx to Tx and don't forget to connect the grounds together.Martin

Two more considerations: making sure you have the right firmware on the Arduino (sometimes it gets corrupt for seemingly no apparent reason and you need to reupload it), and finally making sure that it's getting enough power through RPi's USB port to provide stable operation.

If connecting to serial port works when you run pd with sudo privileges, you will need to add your user is to the dialout group. See http://unix.stackexchange.com/questions/14354/read-write-to-a-serial-port-without-root for more info. HTH

I have done all of that for use with the ardunio uno, it's when the raspi2 is directly connected to the serial pins that it does not connect.
I tested the device on mac and used the ALLINPUTS firmata and it works with a virtual serial created by FTDI
just can't seem to talk to it with Linux debian running vanilla
comport works fine with the UNO

these days mknod is hardly ever needed: instead any devicefiles will be
created on the fly by the resp. drivers.
selecting device in the toggles in the pduino stuff only finds device 0a little bit of googling hints that /dev/ttyAMA0 is indeed the name for
I am wondering if it's a linux issue because the only serial port at all is
serial 0 /dev/ttyAMA0
the serial interface on the GPIO ports - which afaiu is what you want.
so you just use that device.
then you need to get the permissions correct.
check whether the device is already setup to allow group-members to
write to it, and which group that is:
$ ls -l /dev/ttyAMA0
crw-rw---- 1 root dialout 4, 67 Sep 3 16:12 /dev/ttyAMA0
and eventually add the user running Pd to that group:
pd@raspbian $ sudo bash
root@raspbian # adduser pd dialout
after that you only need to re-login as that user to let the new group
membership have any effect.
