Datasheet

On a Pi 3 this will take many many minutes, so don't worry if its taking 15 minutes. On a Pi Zero it can take an hour or

longer!

Prepare to Compile the i2s module

Now you're ready to compile i2s support:

This may already be done - mount: debugs is already mounted - in which case keep going

If you are using Pi 3 or Pi 2 - make sure the module name is 3f203000.i2s

If you are using Pi Zero - the module name is 20203000.i2s
