CCS/EVMK2G: EVMK2G & CMB & MCASP

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:

https://e2e.ti.com/support/dsp/c6000_multi-core_dsps/f/639/p/655489/2423369

Given the jumper settings as per TIDEP-0088 (which BTW are labeled differently on the CMB board, as Rob pointed out J2=J3,   J6=J8,J7=J10, J8=J11), I could verify that the CMB board generates the MCLK, BCLK & LRCLK (e.g. works in master mode).

By checking the wiring mapping to the K2G as per TIDEP-0088, it looks like all the signals from the CMB ADC are connected to the SOC_MCASP1, except the MCLK which is connected to SOC_MCASP2AHCLKX (pin 48 of Audio Expansion connector). This doesn't look right to me. Could you please reproduce the issue, and suggest a solution.

Setup:

K2G Board rev D1.3

CMB: TDA-01454B (latest)

Thank you,
