ALSA linux driver for Bela cape
The Bela cape rev C comes with a ES9080Q 8-channel DAC and a TLV320AIC3104 stereo codec. The former has no support on Linux, while the latter is well supported. This project involves: - writing a driver for the ES9080Q, which interacts with existing McASP and DMA drivers - have the ES9080Q and TLV320AIC3104 show up as a single ALSA device with 2 inputs and 10 outputs. Explore whether this can happen via a simple wrapper in the device tree or requires a dedicated driver.
Goal: Upstream support of ES9080Q; simultaneous access to ES9080Q and TLV320AIC3104 via ALSA
Hardware Skills: basic wiring, logic analyzer
Software Skills: C or Rust, Linux
Possible Mentors: Giulio Moro
Upstream Repository: Design files for the Bela cape Rev C
References: The Bela repo shows how to access these devices with a custom driver and DMA running on the PRU.
