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…
Hi Janardan,
Can you verify that the CMB BCLK is active before you attempt to initialize the McASP?
There is a note in the TRM that states "Before performing McASP global initialization, If external clock ACLKR is used, it must be running already for…
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:

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…
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 the pdk_k2g_1_0_7…
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…
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…
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…
Hello Minjeong,
Thanks for considering TI DSPs. TI DSPs are at the center of embedded solutions with the following advantages:
Real-time, deterministic processing
High performance
Power Efficient
Scalable
Easily Programmable
When you consider which…
Hi Sajad,
You are on the right track.
Check out these links for processors that are well suited for microphone arrays. These solutions can scale with more microphones per board and more EVMs communicating together.
