Raspbian Jessie – Enable ttyAMA0

Posted on Updated on

I spent a bit of time trying to find out how to enable the gpio port /dev/ttyAMA0.

  1. In terminal
    sudo raspi-config
  2. Select 9 Advanced Options
  3. Select A7 Serial
  4. Select No for: Would you like a login shell to be accessible over serial?
  5. reboot
  6. Enable uart in /boot/config.txt
  7. reboot
  8. Done

to check tty:

dmesg | grep tty

Use command-line gpio util to check state of all pins

gpio readall
