Running Wifi audio app on TI-RTOS.

Other Parts Discussed in Thread: CC3200

I've got the CC3200 Audio BoosterPack and successfully make running the "Wifi audio app" example in <cc3200-sdk>\example\wifi_audio_app.

But, I need to change the Wifi audio app example to be running on TI-RTOS rather than running on FreeRTOS, so, I changed the project to TI-RTOS from FreeRTOS, but the callback function(DMAPingPongCompleteAppCB_opt()) for I2S_INT_XDATA was not called.

So,it seems that there're some special required steps for changing FreeRTOS to TI-RTOS when the INT_I2S interrupt is required(like I2S_INT_XDATA), is my understanding correct?

Thanks & B. Regards,

Hi Inbae,

Apologies for delayed response.

Did you optimized code for memory as TI-RTOS need more memory compare to freertos. We ported wifi audio example on TI-RTOS with reducing buffer size and it working without any issue For your reference attaching working TI-RTOS base wifi_audio example(wifi_audio_app_tirtos.zip) . Also to use attached project you need to modify <sdk-path>cc3200-sdk\ti_rtos\ti_rtos_config\app.cfg for increasing heap from default 32K to 64K. Below line you need to change

from

Program.heap = 0x8000

Program.heap = 0x12000
