Tool/software:

Hi,

We want to change the base board from CC1352P1 to CC1353P7-1 due to memory shortage.

As you know, LP-CC1352P7-1 board uses the TI-RTOS7.

We want to migrate from rfAudioTx_CC1352P1_LAUNCHXL_tirtos_ccs program to LP-CC1352P7-1 board.

Please let me know how to migrate ti-rtos based application to ti-rtos7 one.

Thank you very much.

I have a question before migration.

I had a test using i2secho_LP_CC1352P7_tirtos7_ticlang demo program.

But I couldn't hear the sound of mic input.

Are there any options to play the audio?

Attaced fig is the environment for test.

Thank you very much.

From JM KIM.

Hi,

Can you double check your hardware? We have a thorough guide in the Audio plugin:

Not all headpfones/speakers are compatible with the BP.

The other thing to check is to use a logic analyzer to check that the signal is going as expected.

Cheers,

Hi,

We have already tested the example program in audio_plugin_3_30 using CC1352P1.

When I use the opus codec, the sound is good.

We needed the processor with more sram. So we tested the example of i2secho_LP_CC1352P7_tirtos7_ticlang

in stead of rfAudioTx_CC1352P1_LAUNCHXL_tirtos_ccs in the LP-CC1352P7-1 board with the same audio board.

Because rfAudioTx example is not provided in LP-CC1352P7-1 board.

Have you tested the i2secho_LP_CC1352P7_tirtos7_ticlang in the CC1352P7?

Thanks.
