PROCESSOR-SDK-AM62X: Testing the MMCSD RAW IO Application

Part Number: PROCESSOR-SDK-AM62X

Hi Team, 

I am trying to test the MMCSD RAW IO application, Based on the documentation the R5 wake-up firmware should be booted through SBL. 

https://software-dl.ti.com/mcu-plus-sdk/esd/AM62X/08_06_00_18/exports/docs/api_guide_am62x/EXAMPLES_DRIVERS_MMCSD_RAW_IO.html

Is this possible to test the application without SBL boot, with SPL boot (EMMC boot mode)?

Can you please help with the problem?

Thanks and Regards,

Aneesh

    Hello Aneesh,

    Please note that the MMCSD_RAW_IO is a special example which has DM integrated into it. This application when run on Wakeup R5F core serves as the DM firmware. So, if you want to test this example with the SPL boot flow, you can simply replace the Wakeup R5F image used as DM firmware in the PSDK with the image generated in MMCSD_RAW_IO.

    Please refer to the following thread for the guide to replace DM firmware in the PSDK

    For credibility, the screen recording attached below shows the example booting with the SPL boot flow

    Regards,
