1/. which HW module you're referring to? i.e. MCSPI or OSPI as listed below in AM64x TRM?
https://www.ti.com/lit/pdf/spruim2
12.1.4 Multichannel Serial Peripheral Interface (MCSPI)
12.3.2 Octal Serial Peripheral Interface (OSPI)

2/. which SDK SW package, Linux SDK or MCU+SDK?

Hi,

Thanks for clarifying it is MCU+ SDK that you are using.

The functions for MCSPI is located under SDK_INSTALL_PATH/source/drivers/mcspi/v0

Also note, that we have a top level API called, MCSPI_transfer which calls Transmit or Receive API based on the configurations made by the user in the SysConfig tool.

To accelerate development using MCSPI on MCU+ SDK, highly recommended to refer the following:

MCSPI Integration Guide: [FAQ] SK-AM64B: MCSPI Integration Guide

Drivers for MCSPI: https://software-dl.ti.com/mcu-plus-sdk/esd/AM64X/11_01_00_17/exports/docs/api_guide_am64x/DRIVERS_MCSPI_PAGE.html

Examples of MCSPI which comes along with MCU+ SDK: https://software-dl.ti.com/mcu-plus-sdk/esd/AM64X/11_01_00_17/exports/docs/api_guide_am64x/EXAMPLES_DRIVERS_MCSPI_LOOPBACK.html

Hope this helps.

Regards,

Vaibhav
