AM2432: AM243x MCU+ SDK SPI Sample Application

Part Number: AM2432

Hello,

I have a question regarding the TI AM243x MCU+ SDK.

I understand that the SDK provides several sample applications that use SPI. Could you please let me know if there is a sample application, or any reference design, that matches or is similar to the following requirements?

System Configuration

  • An AM243x device is connected to a controller via PCIe.
  • We would like to replace this PCIe connection with an SPI connection.
  • The AM243x boots using SBL (Secondary Bootloader).
  • After booting, the controller downloads and writes the application program to the AM243x over PCIe.
  • The AM243x and the controller currently exchange data by reading and writing each other's memory over PCIe at a cycle time of several hundred microseconds.

Question

Are there any SPI examples in the MCU+ SDK that could be used as a reference for implementing a similar communication architecture over SPI?

Any recommendations regarding relevant examples, libraries, or application notes would be greatly appreciated.

Thank you.

    Hi,

    Currently there is no pre-built example which exists in the SDK catering to your requirements.

    I would suggest looking at sbl_pcie, sbl_pcie_host, MCSPI examples(like MCSPI Performance/MCSPI Loopback).

    Regards,
