TDA4AL-Q1: How can I get the results of the MIPI 、LVDS CRC check with Deserializer MAX96716A 、MAX 96712 sensor,DSI CRC check with DSI3?

Part Number: TDA4AL-Q1

hi ti experts:

due to Function security requirement,there have 4 needs:

1)Monitor and control the traffic of LVDS interface, take security measures to ensure normal communication, and resist denial of service attacks. When there is an abnormal flow situation, it should be dealt with in a timely manner.(LVDS communication anti DDos

2)The MIPI communication between the camera and ECU should be protected using integrity CRC verification methods.(LVDS communication security verification

3)Monitor and control the traffic of DSI interfaces, take security measures to ensure normal communication, and resist denial of service attacks. When there is an abnormal flow situation, it should be dealt with in a timely manner.(DSI communication anti DDos

4)The communication between radar and ECU should use integrity verification methods to protect the communication content.(DSI Communication Security Verification

How do I develop and implement these requirements?

  • Hi,

    Please find answer to your question below.

    #1, for LVDS communication, i think you should read deserializer register to figure out the communication status. Please check deserializer specs to help here.

    #2, CSIRX does support check for CRC status. This is already provided in the driver status and we can get this status by calling driver ioctl. There is also a feature to register a callback on R5F to get notification of this error when error comes. 

    #3, DSI CRC check should be done on the receiver.

    #3, again this should be done on receiver.

  • hi

    #1, deserializer is the MAX96716A, Can you give me some reference materials?

    #3 and #4,receiver is the TDA4AL,so TDA4AL SDK has these descriptions?

  • Hi Kevin,

    For #1, can you please check with Maxim, as i dont have Maxim specs? 

    For #3 and #4, DSI is output from TDA device, so it will embed CRC signature in the out going stream, please check in the receiver device if it is receiving correct CRC.
