Hi Chengxian,

I saw you tried to add the SD file I/O into the multiple channel playback example.

Have you tried the following MMCSD File I/O example?

C:\ti\freertos_sdk_am275x_11_01_00_16\examples\drivers\mmcsd\mmcsd_file_io\am275x-evm\c75ss0-0_freertos.

Best regards,

Ming

Yes, the MMCSD File I/O example can be used to read and write the SD card normally.

Hi Chengxiang,

Can you share your modified multiple channel playback example with SD file I/O?

Best regards,

Hi Chengxiang,

The error was caused by the heap size is too small:

Please change the linker.cmd file from

-heap 0x1000

-heap 0x8000

Best regards,

Ming
