ECC in SDRAM Controller -> how to disable?

Hi All,

how can I disable the ECC in the SDRAM Controller in HPS in ArriaV?

The only option, which I see is the Total Interface Width, which is currently set to 40 (the intention was 32 bits for data and 8 bits for ECC).

So, if I set the Total Interface Width to 32, will it automatically disable the ECC option?

Thank you

    not not mistaken,

    as long as not at below setting the ECC won't kick in

    SDRAM Interface

    The SDRAM interface is up to 40 bits wide and can accommodate 8-bit, 16-bit, 16-bit plus ECC, 32-bit, or

    32-bit plus ECC configurations, depending on the device package. The SDRAM interface supports

    LPDDR2, DDR2, and DDR3 memory protocols.
