Supported Avid devices include: [[Avid E3 Engine]], [[Avid Stage 16]]
+
[[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.

Hardware
 +
; Processor : ARMv7 Processor rev 2 (v7l)
 +
; BogoMIPS : 719.25
 +
; Hardware : Diamond
 +
; RAM : 256M
 +
 +
### 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.

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.

      1. 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.

      1. 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.

Load quartz routing file.

``` diag -quartz loadpre /lib/rt/Bonanza/Stage16.rt ```

The `i2c*` commands don't seem to work on the carbonui devices.

      1. 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.

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.
