Hello:
When I use the development board of the Feiling embedded imx8mini, I encountered the frame count increase when the chip's own network port (eth0) communicates with the servo drive (100Mb/s full duplex), and the recognition rate and work The count already exists in the mode.
I have seen driver or hardware problems in Red Hat’s knowledge base,
https://access.redhat.com/solutions/1189773
In order to rule out the hardware problem, I did a test:
1. eth0 communicates with the switch (1000Mb/s), there is no frame error
2. eth0 communicates with the driver-free USB to network card (100Mb/s), there is no frame error
If it is a driver problem, how should I modify it?
Hope to get your help, thank you!
Hello:
Thank you for your answer. My other development board, imx6q, also reported a frame error but it can communicate normally. It seems to be another problem. Can you continue to help me? imx8q sends Ethercat packets. I use wireshark to capture the packets and observe that the servo returns data, but the master station does not seem to have received the data packets returned by the servo.
Is it a Socket compatibility issue? The kernel of imx8mm has no Socket match support setting
