RTOS: PDK_K2G_1_0_7 demo problem

Wujun He

Tool/software: TI-RTOS

Hi , thank you for your attention;

We want to sample real time voice of 13 Mic on K2GEVM board .We rebuild the PDK_K2G_1_0_7 and get the demos of Audio_evmK2G , AudioEQ_evmK2G and DeviceLoopback_evmK2G correctly as follow :

We want to use these demos to do our project ; but we are not sure that can these demos be run on K2GEVM and CMB board ，this is the first question.

The second questions comes from connections between K2GEVM and CMB, As we know the connection for K2G_bf_rt demo of K2GEVM and CMB is as follow :

While we want to run DeviceLoopback_evmK2G demo on the K2GEVM and CMB , what should we do to deal with hardware connection and software DeviceLoopback_evmK2G demo ? Thank you for your help !

Wujun,

1) The examples such as C:\ti\pdk_k2g_1_0_7\packages\MyExampleProjects\MCASP_Audio_evmK2G_armExampleProject are not designed ot run with the CMB, but rather stand-alone examples that use the EVMK2G's audio hardware. If you want to run these examples with the CMB, you will have to make some changes to the example. For reference, I would suggest taking a look at the software for www.ti.com/.../TIDEP-0088 which is located at C:\ti\processor_sdk_rtos_k2g_4_01_00_06\demos\audio-preprocessing\realtime_demo_bios. This will illustrate how the CMB is configured, etc.

2) For a loopback test that exercices the CMB, please see C:\ti\pdk_k2g_1_0_7\packages\ti\addon\cmb\test\evmK2G\analog\loopback for a diagnostics example. This is a great way to check that the CMB mics are working.

Hope this helps.
