14:32 <Guest46> I all, I am trying to use the PRU UART with the arduino board. I cannot get the UART to read bytes sent from the arduino via Serial.write(). I am using the py-uio package to try and communicate in python

14:32 <jakllsch> is that running on the PRU?

14:32 <jakllsch> or are you otherwise accessing the PRU UART via the main CPU?

14:33 <Guest46> I know the UART code works on the BBB side because the loopback works fine but I cannot seem to get bytes read from the Arduino. I have confirmed that the Arduino sketch works

14:33 <jakllsch> baud rates configured correctly?

14:34 <Guest46> I have not read via the PRU but the  py-uio package has allowed me to drive it outside of a PRU code in the past

14:34 <Guest46> yes bauds match. I tried 9600 and 155200

14:34 <Guest46> baud rates match

14:36 <Guest46> on the arduino side i tried sending just Serial.write(100) and I have tried appending a Serial.write('\r')

14:36 <jakllsch> any potential for hardware flow control or carrier detect problems?

14:37 <Guest46> I am definitely a hobbyist in terms of knowledge, not sure what you mean there?

14:39 <Guest46> I have been looking at the source code https://github.com/mvduin/py-uio/blob/master/src/uio/ti/icss/uart.py

14:40 <Guest46> it is weird that it just hangs. I am wondering if I could call a lower level function to maybe see if I am getting anything in the buffer or something...

17:57 <zmatt> (pinmux?)

17:58 <Guest46> zmatt still around
