Tool/software:

Hello.

My development environment is as follows
  Environment:
    CCS 12.7.0
    MCU-PLUS-SDK-AM243X  10.01.00.32
    LP-AM2434

I get an error when I start the ipc echo sample with SBL OSPI MULTI-PARTITION.

Is this a problem with the SBL?
Or is the LP2434 faulty?

    Hi,

    There is a known bug, which I would like you to incorporate and take into account.

    Basically, when you look at the file ospi_lld.h

    The method OSPI_NOR_PROTOCOL is incorrectly defined.

    The correct definition should be:

    #define OSPI_NOR_PROTOCOL(cmd, addr, data, dtr) (uint32_t)(((uint32_t)(dtr) << 24) | \
                                                            ((uint32_t)(cmd) << 16) | \
                                                            ((uint32_t)(addr) << 8) | \
                                                            ((uint32_t)(data) << 0))
    Notice I have swapped the addr and data field, once you have made these changes please go ahead and rebuild the libraries to incorporate these changes. Also make sure to rebuild the applications.
    Please let me know if you see the issue after this change is made.
    Regards,
    Vaibhav
