I use RT1064, SDK version 2.9.0. The test scenario is that two RT1064 boards send and receive Ethernet messages to each other. The boards are synchronized with the master clock. A timestamp is obtained when sending and another timestamp is obtained when receiving an interrupt. The difference time is the network transmission time. But when ENET_ RXBD_ NUM is 4, I found that the network transmission time is more than 4ms, while ENET_ RXBD_ NUM is 1, the network transmission time is 200us. Why is the difference so large? I have not set RXIC.
Question 1: If ENET_ RXBD_ NUM is set to 1, will it affect the received data and cause frame loss?
Question 2: When I ENET_ RXBD_NUM is set to 4, I find it seems that the time to receive interrupt response is longer than ENET_ RXBD_ NUM is set to 1，Why?
