TMDSEVM5517: C55x_CSL_Audio_Pre-Processing with PCM1864CMBEVM

Kaka

Part Number: TMDSEVM5517

Hi TI Expert,

Now we are trying to run the demonstration of C5517 Audio Pre-processing TI Design with following wiki site.
processors.wiki.ti.com/.../C55x_CSL_Audio_Pre-Processing
But I got some questions to do the run.So, please let me confirm the following questions.
[Question.1]
According to the "Circular Mic Board (CMB) to C5517 EVM Connections", the I2S_BCLK, I2S_LRCLK is connected to J31 pins on EVM. But the PCM1864CMBEVM does not mount the header pins on EVM. Should we mount the pins on EVM?

[Question.2]
On "C5517 Audio Preprocessing TI Design Patch Files" session, I download the patch files from this wiki site, but the C files including the zip file was not correct. Would you please double check that file?

Best regards.

Kaka-san,

Yes, you would need to mount the header on the CMB so that you can access the extra LRCLK and BCLK lines.
The C5517 TI design was written for the LMB (linear mic board) www.ti.com/.../TIDA-01470. The patch files are for using the LMB.

If you are using the CMB (which is the case with you), then the patch files are not needed.
The patch files referred to in the wiki have been fixed, thanks for pointing that out..

Hi Lali,

Thank you for your comment.
I got it. By the way I met other issue when I load the sample demo.
So, I will make another thread.

Best regards.
