Linux/OMAP-L138: Standalone McASP driver

Part Number: OMAP-L138
Other Parts Discussed in Thread: OMAPL138

Tool/software: Linux

Hi,

We want to use the McASP interface with ADC for analog signal sampling. We are using mainline linux kernel v4.10.

I have found the McASP bus driver as a part of Sound Subsystem, and the driver implementation is tightly coupled with the sound subsystem. Is there a standalone McASP driver which we could use? Is it possible to use the sound subsystem purely to record data from McASP interface into a kernel buffer?


Any recommendation is appreciated.

Thank you for help

    Hi Robert,

    Is there a standalone McASP driver which we could use?

    The closest to a standalone driver is the MCASP audio example project in OMAP-L138 RTOS, located in:
    pdk_OMAPL138_1_01_00_02/packages/ti/drv/exampleProjects/MCASP_AudioExampleProject
    Have a look at its sources.

    Best Regards,
    Yordan
