AM2634: Flash Write QSPI Driver

Dominik Wuest

Part Number: AM2634


Tool/software:

Hello

We are using the Board Flash Driver from the current SDK (TI_mcu_plus_sdk_am263x_10_02_00_13).

Since we are using the external flash as ring memory, we want to write smaller units than 256 bytes (page size). Our external flash support write commands with 1-256 Byte. 

What is the best way to do this? Rewrite "Flash_norQspiWrite" function or do you see better solutions?

Best regards

Dominik

    I made a custom "Flash_norQspiWrite" function. Testing was successful.

    There is only a small modification needed:

    Change 

        /* Check offset alignment */
    if(0 != (offset % attrs->pageSize))
    {
        status = SystemP_FAILURE;
    }
    to 
        /* Modified check offset alignment */
    {
        int32_t pageOffset = offset % attrs->pageSize;

        if(0 != pageOffset)
        {
            /* Prevent page wrapping */
            if ((pageOffset+len) > attrs->pageSize) {
                status = SystemP_FAILURE;
            }
        }
    }
