Hey users,

I ve got a problem using UE306 adapter linked up to (RISC-V) Microcontroller via RJ-45:

 

With WireShark (eth sniffer) i can see UDP and TCP packages, but i cant transmit ARP or ICMP from MCU to PC using EU306. When i connect MCU to PC using motherboard LAN - it s all OK, ARP requests and replies work fine.

I see indicator of EU306 blincking while MCU transmitts ICMP or ARP packages, but nothing appears in WireShark sniffer.

 

I tried to change some params in driver settings but it doesnt help. And i tried EU306 on other PC - same issue. PS Firewalls disabled. Network setup: 10 mbit, full-duplex.

 

1) Why cant i see any ICMP or APR protocol packages from MCU on WireShark(PC) using EU306 to connect MCU to PC(Windows)?

 

I would be grateful for any ideas about this issue.

Problem was caused by frame length < 60 bytes.

UE306 based on Asix AX88179 drop out these packages.
