AM3352: How to use McASP to read the ROM data and send it to the codec

Conor

Part Number: AM3352

Hi,

My customer is using McASP of AM3352 to create a program that reads the data in ROM and sends it to the codec.
Development uses CCS.

The processing functions are as follows.

■ Output ROM data to EDMA
■ Reading McASP from EDMA
■ Writing from McASP to the codec

Could you give me some sample code and required functions to achieve the above three behaviors?

SDK: sdk_rtos_am335x_6_03_00_106
CCS: Ver.10.0.2

Thanks,

Hi Koki,

The best place to get started is to use the MCASP LLD examples in the Processor SDK RTOS :

https://software-dl.ti.com/processor-sdk-rtos/esd/docs/06_03_00_106/rtos/index_device_drv.html#mcasp

I am guessing the customer is using TI EVM for this evaluation so please generate the CCS project for MCASP examples using PdkProjectCreate and import in CCS.

The example does a loop back of data from RX to TX serializer. This is the best starting point available.

Please clarify what you mean by read ROM data to EDMA, I am not sure that I understand the usecase. Please use graphic if possible for clarity

Regards,

Rahul
