xCORE VocalFusion Raspberry Pi Setup

This repository provides a simple-to-use automated script to configure the Raspberry Pi to use xCORE VocalFusion for audio.

Note: This repository is designed for use within the following xCORE VocalFusion repository:

• xCORE VocalFusion Kit for AVS: https://github.com/xmos/vocalfusion-avs-setup

This setup will perform the following operations:

• enable the I2S, I2C and SPI interfaces
• install the Raspberry Pi kernel headers
• install the required packages
• compile the I2S drivers
• add a cron job to load the I2S drivers at boot up

For XVF3510 devices these actions will be done as well:

• configure MCLK at 24576kHz from pin 7 (BCM 4)
• configure I2S BCLK at 3072kHz from pin 12 (BCM18)
• update the alias for Audacity
• add a cron job to reset the device at boot up
• add a cron job to configure the DAC at boot up

Setup

1. Install Raspbian Buster on the Raspberry Pi.

2. Ensure running kernel version matches headers kernel headers package. A typical system requires the following --reinstall command:

   sudo apt-get update sudo apt-get install --reinstall raspberrypi-bootloader raspberrypi-kernel

   followed by a reboot.

3. Clone the Github repository https://github.com/xmos/vocalfusion-rpi-setup:

   git clone https://github.com/xmos/vocalfusion-rpi-setup

4. For VocalFusion devices, run the installation script as follows:

   ./setup.sh xvf3100

   For VocalFusion Stereo devices, run the installation script as follows:

   ./setup.sh xvf3500

   For XVF3510 devices, run the installation script as follows:

   ./setup.sh xvf3510

   Wait for the script to complete the installation. This can take several minutes.

5. Reboot the Raspberry Pi.
