Pi Minimal boot

[bear-in-the-air]

As a musician I would like the vocoder to boot quickly and launch directly in to the vocoder software.

Sucess criteria

• unnecessary OS components disabled
• vocoder software launches with boot
• method to switch between minimal boot and full boot to update and debug software

For this to work we will need to tell ALSA which devices on the codec zero we want to use (AUX in, AUX out). This can be done with a script as specified here: https://www.raspberrypi.com/documentation/accessories/audio.html#codec-zero-configuration

Using raspi-config in Rasbian the Pi can be set to a command line only boot mode which doesn't load X server or the desktop, considerably reducing boot time and background RAM and CPU use.

The software once compiled can be run on boot with a script called on bash startup, once it is completed.
