6.4.5 Validated Build Options

The reference design can be built in several ways by changing the build options.
These are described in §7.1.
The design has only been fully validated against the build options as set in the
application as distributed. See
These fully validated build configurations are listed below. In practise, due to the
similarities between the U-Series and L-Series feature set, it is fully expected that
all listed U-Series configurations will operate as expected on the L-Series and vice
versa.
6.4.5.1 Configuration 2ioxs
This configuration runs in high-speed Audio Class 2.0 mode, has the mixer disabled,
supports 2 channels in, 2 channels out, supports sample rates up to 192kHz and
S/PDIF transmit.
6.4.5.2 Configuration 2iomx
This configuration disables S/PDIF and enables MIDI.
This configuration can be achieved by in the Makefile by defining SPDIF_TX as zero:
- DSPDIF_TX =0
and MIDI as 1:
- DMIDI =1
6.4.5.3 Configuration 2ixxx
This configuration is input only ( NUM_USB_CHAN_OUT set to zero). I.e. a microphone
application or similar.
6.4.5.4 Configuration 1ioxs
This configuration is similar to the first configuration apart from it runs in Audio
1.0 over full-speed USB.
This is achieved in the Makefile by:
- DAUDIO_CLASS =1
XM0088546.1
