TMDSEVM5517: C55x CSL Audio pre-processing

Frangline

Part Number: TMDSEVM5517

hi,

When I tried the C55x CSL Audio pre-processing demo using CMB based on the information provided in this link,

processors.wiki.ti.com/.../C55x_CSL_Audio_Pre-Processing

the demo didn't work initially. While debugging I found that the HW connection information may be wrong. Could some one please verify this and update the document.

I had to swap/connect CMB_DATA1 (D1) to J28_P2 to get the demo working [From the documentation CMB_DATA1 (D1) is connected to J30_pin2].

regards,

Frangline.

Fragline,

Which software are you using? Is it based on the TI design guide www.ti.com/.../TIDEP-0077 and CSL 3.07?
This guide is geared toward the 4 mic linear LMB, but can also work with the CMB.

hi,
yes, software is from c55_csl_3.07.
HW used is CMB and 5517 EVM and I follow the connections as described in
processors.wiki.ti.com/.../C55x_CSL_Audio_Pre-Processing
I guess that the SW patches are required for c55_csl_3.07 + LMB; I did not use the patches.
regards,
Frangline.
