Other Parts Discussed in Thread: 66AK2G02 , TIDEP-0088 , AUDK2G Tool/software: TI-RTOS Hi , thank you for your help
From TI Designs: TIDEP-0088 Audio Pre-Processing System Reference Design for Voice-Based Applications Using 66AK2G02. We know that in…
Part Number: EVMK2G Tool/software: Code Composer Studio Hi,
I could reproduce the same issue of MCASP failure during the audioAnalogLoopbackTest initialization, that was signaled by Rob in:

Rahul,
I think you might have a different project in mind. The 2.2.4.2 section named audioAnalogLoopbackTest in the tiducr7a.pdf, which is the main documento for TIDEP-0088 reference design specifically states that "The cmb project is part of the Processor…
Rafael,
As I'm seeing you are using coefficients generated by bfgui.exe tool as it is described at:
training.ti.com/.../Voice-Processing-Tools-Software-SLIDES.pdf
but the coefficients can vary depending on Beamformer parameters as it is described…
Hi Yimin,
There are various solutions to connect 4 microphones to C6746 based board but I suggest you some resources about PCM1864 4-Channel Software-Controlled Audio ADC which can be connected via McASP.
You can use for reference design TMDSLCDK6748…
This design is now available on ti.com here:

Please let us know if you find any design files/schematics missing in the links provided on the Design folder.

Hi Lenin,
You are correct. The CMB board has DSP header which has BCK and LRCK signals which can be connected to the AM5728 I2S interface. In addition, below table lists the rest of the signals that you can interface with the CMB to communicate w. the…
Morgan,
Unfortunately, there isn't a voice trigger demo for the C67x, it only exists for C55x. Porting the demo from C55x to C66x isn't trivial since C66x is 32-bit floating point and C55x is 16-bit fixed point.
- There is a voice processing TI…

The board we designed is not same as the TI design (TIDEP-0088). I find the failture of output MICBIAS PCM1864 devices, because output is low .we have ordered the CMB board but we have not get it at present . I have another problem , the address…
The TI design that you referred is a audio equalizer example that takes data from audio Line in and processes the data and sends the data out from Line out. The design does use AIC3106 for converting audio to digital input to MCASP on K2G . The same concept…
