Avid devices including the Diamond Platform embedded Linux controller include: - Avid E3 Engine - Avid E6 Engine - Avid Stage 16 - Avid Stage 64
This controller connects to all of the ADC (Analog to Digital Converters), and runs the `avbd` daemon, which provides AVB connectivity. The `avdecc` and `diag` commands are used for configuring the ADCs.
Both the E3 Engine and the Stage16 contain this Linux device.

- Operating system**
The OS is Linux, and looks to be named "Bonanza Green Salamander". On the S3L-X 4.6.1.4 release this OS version is 1.2.0.152.
- Networking**
This controller provides two Ethernet interfaces, `eth0` and `eth0:avahi` (a virtual interface managed by `avahi-daemon`).
The `eth0:avahi` interface has a link-local address that is available even though the `eth0` interface, and is accessible using the address `diamondXXXX.local`, where `XXXX` is replaced by the hex characters of the last two octets of the system MAC address.

- Quartz
Configure INSA for Audio IO. From `/usr/sbin/avb_dd_io.sh` (as `/opt/etc/routing_layout.sh`).
``` diag -quartz write 0xc00 0x501 ```
Load quartz routing file.
``` diag -quartz loadpre /lib/rt/Bonanza/Stage16.rt ```
[Un]mute IO boards – change will be reflected within Avid VENUE
``` diag -iomute 0 # unmute diag -iomute 1 # mute ```
- Devices
- /sys/bus/i2c/devices
Device numbers:
- 1 (bus 1)
- generic
- 4 (bus 4)
- carbonui
The `i2c*` commands don't seem to work on the carbonui devices.
- carbonio (/sys/bus/spi/devices)
carbonio is a Linux module that directly controls the audio I/O devices.
Audio settings that can be controlled: - Gain - Pad - Phase - Mute - Phantom
Non-audio settings that can be controlled: - LEDs on the Avid Stage 16 - The opamp (operational amplifier) for each channel.
`/sys/bus/spi/devices`
Device overview:
- spi1.[0-8]
- channel gain and pad
- spi2.[0-3]
- unknown
- spi3.[0-2]
- unknown
- spi4.0
- power, mute, phantom, and status LEDs
The `_en` extension on some files represents "enable".

- (\*1)** Each directory controls a bank of 4 channels. The directory 0 or 4: Ch 8-5, 1 or 5: Ch 4-1, 2: Ch 12-9 3: Ch 16-13). E.g., `spi1` channel #1 == `spi1.1/ch3_*`. **NOTE:** Changing file values directly will not be reflected in the VENUE UI.
- (\*2)** The `preamp_gain` values are set to 0 before the device is first initialized by the E3 Engine.
- /usr/bin/carbonui-util.sh**
This command seems to control the LEDs on the Avid S3 console using the `/sys/kernel/carbonui/oled` interface.
- /usr/bin/carbonio-dump.sh**
This command dumps the values of the IO board devices in `/sys/bus/spi/devices`.
