Dear @vighbalazs,
Thank you for your reply.
At the moment, this would be a hardware limitation because of Jumbo frames limitation. If you are expecting a very quick fix, we would like to suggest to use 100Mbit speed, there is a registry for that.
Theoretically, You need to play around below options for the problem if there is no hardware limitation
- Socket buffer
- Ethernet large packet
- Increase ethernet queue
We found this documentation : https://www.researchgate.net/publication/317300297_Achieveing_reliable_UDP_transmission_at_10_Gbs_using_BSD_socket_for_data_acquisition_systems, this would be quite useful for you.
Please refer this thread for Ethernet jumbo frame limitation : https://www.toradex.com/community/questions/32274/enable-jumbo-frames-for-ethernet.html
Could you share module serial number with version information, clear top view photo would be very helpful. I will try to verify from the production log messages, Is there any such hardware problem?
Hence, we would like to suggest to use Linux and play around with 3 options to find the optimum settings to suppress the packet loss error on UDP with 1GB speed. Also, please share it with us. We will try to set similar settings in WinCE. As you know, at the moment this would be a time-consuming task for us.
Thank you for your understanding.
