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 § 5.3 for details and binary naming scheme.
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:
- D S P D I F _ T X =0
and
MIDI
as 1:
- D M I D I =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:
- D A U D I O _ C L A S S =1
