I am trying to write values to SFLASH but it is not writing. When I read SFLASH before and after writing, I get the same values.  Therefore, I think that the problem is in the writing part of code.

My code is below:

    uint32_t pos;

    sflash_handle_t sflash_handle;

    data_transfer_area_t data_transfer;

    data_transfer.data[0] = 10;

    data_transfer.data[1] = 200;

    int i = 0;

    for(; i<4*1024;i++)

        data_transfer.data = i+1;

    data_transfer.size = 8*1024;//sizeof(data_transfer.data[0] ) * 2;

    bootloader_app_header_t image_header;

    /* Initialise the serial flash driver */

    init_sflash( &sflash_handle, 0, SFLASH_WRITE_ALLOWED );

    sflash_read( &sflash_handle, 0, &image_header, sizeof( image_header ) );

    data_transfer.dest_address = image_header.size_of_app;

    /* Write into memory */

    pos = 0;

    while ( pos < data_transfer.size )

    {

        uint32_t write_size = ( data_transfer.size - pos > WRITE_CHUNK_SIZE )? WRITE_CHUNK_SIZE : data_transfer.size - pos;

        sflash_write( &sflash_handle, pos + data_transfer.dest_address, &data_transfer.data[pos], write_size );

        pos += write_size;

        watchdog_kick( );

    }

    /* Read data from SPI FLASH memory */

    pos = 0;

    while ( pos < data_transfer.size )

    {

        uint32_t read_size = 4*1024;//sizeof(data_transfer.data[0] );//( data_transfer_receive.size - pos > sizeof(Rx_Buffer) )? sizeof(Rx_Buffer) : data_transfer_receive.size - pos;

        sflash_read( &sflash_handle, pos + data_transfer.dest_address, Rx_Buffer, read_size );

        int i = 0;

        for(; i<12;i++)

            printf("data %d = %d \r\n", i,Rx_Buffer);

        printf("pos = %lu \r\n------", pos);

        pos += read_size;

        watchdog_kick( );

    }

Best Regards

Hello,

I would recommend referring to the sflash_write application in the following location:

WICED\WICED-SDK-2.4.1\WICED-SDK\apps\waf

Hope that helps.

Thanks,

Arsh Buch
