QSPIFBlockDevice : SFPD parsing failed when calling init()

Calling the init function on QSPIBlockDevice results in status -4002 SFDP Parsing failed, unexpected format or values in one of the SFDP tables.

How do I debug this problem? Is there a config that I can do on mbed, or do I need to configure the device ?

From the datasheet the device does contain an SFPD table (page 39)

I can also find references to the model in mbed source files under mbed-os/tests/mbed_hal/qspi/flash_configs The header files should be enabled for my board.

The Quad SPI device is : Micron N25Q128A<br /> The board is : STM32F746NG

include the mbed library with this snippet

QSPIFBlockDevice qspi(PD_11, PD_12, PE_2, PD_13, PB_2, PB_6, 0);
int status = qspi.init();
    
    switch (status)
    {
    case QSPIF_BD_ERROR_OK:
    {
        bd_size_t read_size = qspi.get_read_size();
        bd_size_t program_size = qspi.get_program_size();
        bd_size_t erase_size = qspi.get_erase_size();
        bd_size_t size = qspi.size();
        log->info(LOG_QSPI, "QSPI init [%d] read_size: %lld B program_size: %lld B erase_size: %lld B size: %lld B", status, read_size, program_size, erase_size, size);
        break;
    }
    case QSPIF_BD_ERROR_DEVICE_ERROR:
        log->error(LOG_QSPI, "QSPI init [%d] Device specific error", status);
        break;
    case QSPIF_BD_ERROR_PARSING_FAILED:
        log->error(LOG_QSPI, "QSPI init [%d] SFPD parsing failed", status);
        break;
    case QSPIF_BD_ERROR_READY_FAILED:
        log->error(LOG_QSPI, "QSPI init [%d] Wait for  Mem Ready failed", status);
        break;
    case QSPIF_BD_ERROR_WREN_FAILED:
        log->error(LOG_QSPI, "QSPI init [%d] Write Enable Failed", status);
        break;
    case QSPIF_BD_ERROR_INVALID_ERASE_PARAMS:
        log->error(LOG_QSPI, "QSPI init [%d] Erase command not on sector aligned addresses or exceeds device size", status);
        break;
    case QSPIF_BD_ERROR_DEVICE_NOT_UNIQE:
        log->error(LOG_QSPI, "QSPI init [%d] Only one instance per csel is allowed", status);
        break;
    case QSPIF_BD_ERROR_DEVICE_MAX_EXCEED:
        log->error(LOG_QSPI, "QSPI init [%d] Max active QSPIF devices exceeded", status);
        break;
    }
