How to build the USB-Audio 2.0 sample in XDE 11.11? (errors)

[isymc]

I followed the instructions in the quick start manual and imported the downloaded sample code 'USB-Audio-2.0-XS1-L2-Software-Release(5.3)[11.2.0].zip' to an empty workspace in XDE 11.11.1.

First I get a lot of 'Unresolved Include" warnings in some .xc code files. Running the build process shows several errors:

I successfully built an simulated some new applications (my own code) based on the 'github howto' instructions, but I can't get the USB reference code to build without errors/warnings.

Maybe it's a version mismatch problem between XDE 11.2 and 11.11, thus the project structure looks somewhat different.

There is an XDE option to create a new project based on an legacy project but it does not allow to import from external location/archive.


Any hint welcome ;)

Update ...

I could get rid of the 'unresolved include' and 'external scanner' errors by creating a new XDE project and manually adding the files via drag&drop.

Still leaving a bunch of warnings:

Update++

Builds and runs now, but...

Code: Select all

#warning USING FAST MIXER
#warning IN Vols in mixer, AFTER mix & map	
#warning OUT Vols in mixer, AFTER mix & map

There is a switch for conditional compilation but not explained why setting this switch may cause problems.

Isn't 'fast mixer' a good mixer or does it cause unwanted heavy processor load ... so what?

If 'Out Vols after mix&map' is a bad idea why is it enabled in the USB reference code?


Further I really can't figure out what's going wrong here...

Code: Select all

control reaches end of non-void function   sw_usb_audio_l2  ...XMOS\DevelopmentTools\11.11.1\target\include\flash.h

Any hint?

Fast mixer is fine, its fast but no very easy to read code (this is why the original version is left in). The fast version actually modifies instructions during configuration.

These warnings are just for info really, do not worry about it (it is just a way of getting info to the user during build)
