TDA4VM: CSI_TX cross IFE ERROR

Part Number: TDA4VM


hi expert

When we use csitx to send data, the receiving end occasionally reports an IFE error. Does TDA4 have registers for data integrity and continuity checks?

    Hi,

    What is IFE error? Can you please elaborate?  

    Well, MIPI protocol integrates data integrity checks. There are ECC and CRC added in MIPI packets and the receiver should check for the errors by looking into these fields.

    hi expert

    thanks for your replay

    it means when csitx sends data, it has checked whether the sent mipi data is complete and checked that the sent data conforms to the minimum data length of mipi.

    Hi Zhang,

    Well, data integrity check is already done by the MIPI, each packet is embedded with the CRC and ECC checks. So receiver should just check for these mechanism.

    I did not get the second statement, "checked that the sent data conforms to the minimum data length of mipi", what does this mean? can you please elaborate?
