Dear Forum,
I have problems with enabling serial port communication with Volumio.
My system is:
- a Raspberry Pi 3B,
- no DAC,
- Volumio 2.452 (volumio-2.452-2018-08-27-pi.img)
As soon as I try to enable the serial communication via the “normal” ways, the RPI will not boot properly anymore.
The normal ways I tried out were:
- adding “enable_uart=1” to the /boot/config.txt file
- installing raspi-config, running it, disabling the console via serial and enabling the serial port
This would do it for Raspbian Wheezy and/or Stretch, and I’ve tested it out there and got everything to work.
But with Volumio, as soon as the RPI is rebooted after this step, the system hangs; the red power LED is on, but the green activity LED does not light, the system is unreachable via SSH, and there is no connection to the WEB UI.
Only when I remove the “enable_uart=1” from the /boot/config.txt, the system boots again…
Perhaps I’ve missed something crucial here, or should do it differently?
I would greatly appreciate any help or pointers here!
Thank ever so much,
Gerben.
P.S.1. I’ve seen another post on this forum with the same problem, but no response yet.
P.S.2. The purpose behind this all is to develop a plugin for serial communication to an Arduino which handles the HMI and can control Volumio over the serial connection between Arduino and RPI.
