AWR2944: Fail to get time stamp from Enet HW driver.

Part Number: AWR2944

Hi,

We encounter an issue in the test of Enet time synchronization, we are unable to get the time stamp from HW driver.

The description of the issue is as follows.

ISR "Eth_RxIrqHdlr_0" can enter when the MCU receive the time sync message. but the value of register "CPSW_CPTS_INTSTAT_RAW_REG" is always 0.

that means there is no event generation. so the ISR will not process the EVENT and then return .

 .

as the description in the datasheet, we need to read the event 0-4 register value, then the next step can be executed. now we can not read any value from the register.

so we failed to get the time stamp from "Eth_GetIngressTimeStamp".

Could you give us adivce to fix the issue .

Thanks.

BR,
