  • emFile and NOR Flash problem

    I am trying to use emFile with SST39VF3201B microchip NOR flash.
    The code is:


    void FS_X_AddDevices(void) {

    FS_AssignMemory(&_aMemBlock[0], sizeof(_aMemBlock));

    // Add driver
    FS_AddDevice(&FS_NOR_Driver);

    // Set physical type, single CFI compliant NOR flash chips with 16 bit interface
    FS_NOR_SetPhyType(0, &FS_NOR_PHY_CFI_1x16);

    // Configure a single NOR flash interface (4 Mbytes)

    FS_NOR_Configure(0, NOR_FLASH_BASE, NOR_FLASH_BASE, 0x00400000);
    }



    void MainTask(void)
    {
    FS_NOR_DISK_INFO DiskInfo;

    NORFLASHInit();

    FS_Init();

    // Check if low-level format is required
    if (FS_IsLLFormatted("") == 0)
    {
    printf("Volume is not low-level formatted. Low level formatting...\n");
    FS_FormatLow("");
    }

    // Check if volume needs to be high level formatted.
    if (FS_IsHLFormatted("") == 0)
    {
    printf("Volume is not high-level formatted. High level formatting...\n");
    FS_Format("", NULL);
    }

    ShowDiskInfo(&DiskInfo);

    while (1)
    {
    OS_Delay(100);
    }
    }


    void ShowDiskInfo(FS_NOR_DISK_INFO* pDiskInfo)
    {
    char acBuffer[80];

    FS_X_Log("Disk Info: \n");
    FS_NOR_GetDiskInfo(0, pDiskInfo);
    sprintf(acBuffer," Physical sectors: %d\n"
    " Logical sectors : %d\n"
    " Used sectors: %d\n", pDiskInfo->NumPhysSectors, pDiskInfo->NumLogSectors, pDiskInfo->NumUsedSectors);
    FS_X_Log(acBuffer);
    }

    But the result is:


    FS warning: NOR: Found multiple work sectors of identical size. Low level format invalid.
    Volume is not low-level formatted. Low level formatting...
    FS warning: NOR: Found multiple work sectors of identical size. Low level format invalid.
    FS warning: NOR: Found multiple work sectors of identical size. Low level format invalid.
    FS error: FS_LocatePartition: Invalid BytesPerSector value: 0.

    FS error: FS_FAT_CheckBPB: Invalid BytesPerSector value: 0.

    Volume is not high-level formatted. High level formatting...
    FS warning: NOR: Found multiple work sectors of identical size. Low level format invalid.
    FS error: FS_LocatePartition: Invalid BytesPerSector value: 0.

    Disk Info:
    Physical sectors: 1024
    Logical sectors : 6442
    Used sectors: 0

    What is the problem ?
    Can anyone help me ?
    Best regards.

  • Hi Leonardo,

    Are you using emFile v 4.00?
    In this case, you should read chapter "15.1 Differences from version 3.x to 4.x" in UM02001_emFile.pdf.

    ... or (what it boils down to) try adding

    Source Code

    1. FS_NOR_SPI_SetHWType(0, &FS_NOR_HW_ST_M25_Default);

    just after FS_NOR_SetPhyType(0, &FS_NOR_PHY_CFI_1x16);

    just a guess

  • Stefan,

    Thank you for your help.
    Since I am evaluating emFile I think that there is no v4.0 compilation for Keil and LPC1788.
    I used FS_NOR_PHY_CFI_1x16 physical layer because my NOR is parallel and no SPI.
    I solved the problem by re-writing the physical layer.
    Thank you again for your help.
    Best regards.


    Leonardo.
