AM2632-Q1: Adding QSPI to working project causes the project to ABORT in the QSPI initiailzation code

Jeffrey Hanzlik
Prodigy 90 points
Part Number: AM2632-Q1
Other Parts Discussed in Thread: SYSCONFIG

Tool/software:

I have just migrated our project from MCU SDK 9 to MCU SDK 10.01.00.31 and Syscfg 1.22.  The project built and ran as expected.  I have ran the project on the Control card.  I add the QSPI device to the syscfg for the project.  

The application runs until is gets to the QSPI_open(), this function is in qspi.c of the SDK.  The function never returns.  A pause in the debugger shows that it is in the ABORT handler.

NOTE: If I remove the QSPI device from syscfg things work correctly.  We are not using the QSPI device in our application just trying to add it so that we can do work.

    I have a zip file of the project ready to share.  The insert file does not appear to let me attach the file.  It is a small file ~100KB.

    Hi Jeffrey,

    I have assigned this query to out SW / Sysconfig expert. 

    Jeffrey Hanzlik said:

    Can you please help me understand this statement and  your usecase.

    Can you please help us with the below information: 

    1. Which API in the QSPI_open() did the fail occur?
    2. What type of abort is it ? Prefetch / data
    3. Screenshots of the Sysconfig configurations , MPU region configurations 


    Regards,
    Rijohn

    Rijohn,

    This is the flow into the QSPI driver

    ti/mcu_plus_sdk_am263x_10_01_00_31/source/drivers/qspi/v0/qspi.c
    - QSPI_open()

    ti/mcu_plus_sdk_am263x_10_01_00_31/source/drivers/qspi/v0/qspi_lld.c
    - QSPI_lld_initDma()
    - QSPI_programInstance() line 913.

    The ABORT is handled:

    ABORT:
    ti/mcu_plus_sdk_am263x_10_01_00_31/source/kernel/freertos/dpl/r5/HwIP_armv7r_handlers_freertos_asm.c

    I am not certain how to determine the type of abort.  Can you provide some guidance.

    This is memory region information from Syscfg

    Hi,
    you can check the call stack/debug window  in CCS, it will look like the attached image. See if its DATA abort or something else.

    Thank you  I will add that information.

    Additional information.  I consulted the basic hello world FreeRtos  sample.  I used its memory region configuration as a reference for our application.  I removed the extra regions.  I also modified a couple of regions to match what the hello world config.  The only region I had to change from HelloWorld was OCRAM.  I had to increase it from the 256KB to 1.5MB.  Our application is currently ~600KB.  The changes allowed the application to work as expected.  

    My assumption is that we had some invalid memory region settings.
