Hello @Ttian.3​ ,

It will be difficult to help you unless you provide more details about your case and configuration.

Did you tried the examples available in the Cube packages? or facing this issue with CubeMX generated code?

Let me return to this old question. I got stuck in the same situation. Under stress-test I get ETH_DMACSR_RBU (Rx DMA error) after a few minutes of operation. HAL driver code is a newest from STM32 github.com page. An ethernetif.c is also taken from recent H7 example. Just recreating DMX descriptors table doesn't help.
