SJA1105Q timestamp

[BravoEven]

Hello, I want to configure the timestamp function via SJA1105, but if it is used when using filter mode

MAC_FLTRES address of the [0] threshold as the destination address, it seems that it will be discarded, and there is no wait for the META frame, the corresponding setting is as follows, is it necessary to set it elsewhere? Another TCAM setting forwarding rules I also didn't understand, pain, solve! Thank you！

Hi @BravoEven 

In order to use timestamping, it's necessary to use frame trapping (this is explained in more detail in the AH1704 (7.3 Timestamping and AVB).

Also please read chapter 7.3.3 1-step and 2-step SYNC frames.
An example for gPTP can be found in chapter 7.6.6 of the respective application hints.

Regards,

Lukas

Hello：

    I have just config the trap function by the way shown of the picture below, but I am not sure the red circle part , I do not write any L2 address table via nether static nor dynamic interface, I just open the dynamic learn of all ports. A frame with certain address as destination address can not be trapped and sent to Host port!!!
