Hi,

To make the Fls works with Autosar Fee module, I have to do some changes in Fls driver.

in function Fls_Ospi_readDirect:

#if 0
    remainSize = (uint32)trans->count & 3U;
    size = (uint32)trans->count - remainSize;
    /* Transfer the data in 32-bit size */
    for (i = 0U; i < size; i += 4U)
    {
        HW_WR_REG32(pDst + i, HW_RD_REG32(pSrc + i));
    }
    /* Transfer the remaining data in 8-bit size */
    for (i = 0; i < remainSize; i++)
    {
        HW_WR_REG32(pDst + size + i, HW_RD_REG8(pSrc + size + i));
    }
#endif
    /* This code is used to replace the comment out code above

    for (i = 0; i < trans->count; i++)
    {

    pSrc = (uint8 *)(FLS_BASE_ADDRESS + addrOffset);
#if 0
    remainSize = (uint32)trans->count & 3U;
    size = (uint32)trans->count - remainSize;
    /* Transfer the data in 32-bit size */
    for (i = 0U; i < size; i += 4U)
    {
        HW_WR_REG32(pDst + i, HW_RD_REG32(pSrc + i));
    }
    /* Transfer the remaining data in 8-bit size */
    for (i = 0; i < remainSize; i++)
    {
        HW_WR_REG32(pDst + size + i, HW_RD_REG8(pSrc + size + i));
    }
#endif
    /* This code is used to replace the comment out code above

    */
    for (i = 0; i < trans->count; i++)
    {
        HW_WR_REG32(pDst + i, HW_RD_REG8(pSrc + i));
    }

The other one is that I need to clear the register that was set by RBL.

HW_WR_FIELD32(FLS_OSPI_CTRL_BASE_ADDR + OSPI_DEV_INSTR_RD_CONFIG_REG, OSPI_DEV_INSTR_RD_CONFIG_REG_DUMMY_RD_CLK_CYCLES_FLD, 0);

Otherwise, I have to configure dummy cycle to 8 which may not necessary for us.

Please include those fix in the next mcal release.

thanks
