raspberry ttyAMA0 permissions

Hi, i have to make the serial port ttyAMA0 accessible to non root user to run a python application that uses it. I changed the /dev/mdev.conf file adding ttyAMA0 root:tty 0660 right above the ttyUSB... line. After committing and rebooting the changes seems not to take effect unless i run mdev -s manually. Once i start the python application, the serial port reverts to root:root 0640 permission automatically crashing the app. Am I missing something in the mdev confguration? Thanks for support

To upload designs, you'll need to enable LFS and have admin enable hashed storage. More information
