Thank you all for your responses.
Finally I found the solution: long time ago I had problem with
ETH_IRQHandler and I disabled High priority task woken
void ETH_IRQHandler(void)
{
portBASE_TYPE xHigherPriorityTaskWoken = pdFALSE;

Hello,
I changed my PHY from DP83848 in MII to LAN8720 in RMII. Initialisation in
code seems correct, and signals also (REFCLOCK...)
But I got a strange ping answer starts at 500ms, decrease to 1ms and roll
again.
I test my webserver and it is also very slow.
Hi, this is the kind of problem I love to figure out and not have it
myself... ;^)
1) I would put a wireshark or equivalent to really see what is going on,
those text reports can be lots of non-related stuff. I guess packets
have an id number and so lost packets are detected, but I don't see that
Hi pcu
I am also using the LAN8720 in RMII, together with an STM32F4 and FreeRTOS.
I also had an issue with lost packages. That was solved by a patch provided in
this list.

Hi
Just to clear things out here, you are saying you didn't change anything in
the ethernetif layer and interrupt/DMA handling when you changed PHY? Just
based on the strange pattern on those wraparound delays it looks to me
