Nucleo-STM32F429ZI Ethernet + LWIP (RAW API) - doesn't work.
I've got a project in which I have to communicate by Ethernet (TCP) Nucleo-STM32F429ZI with PC. STM32 will be sending the data from sensor periodically. I'm using STM32CubeIDE with built in CubeMX. I've connected the STM32 and the PC with a crossed cable. I configured it without RTOS, only using LwIP in RAW API mode with static IP addresses. I’m calling the MX_LWIP_Process() function in while loop.
My problem is that I can't receive ping response from STM32 and I’m getting the “Destination Host Unreachable�? message. I've tried every configuration and advice I found on forums and it didn't work. I've tried to adapt my project configuration to that from the example for my board (LwIP_HTTP_Server_Netconn_RTOS which works and response) but it didn't work too.
As I'm debugging my project I can receive the ARP frame with request for IP address and I can see in debugger that the output frame is correct but as the whole payload is passed to "HAL_ETH_TransmitFrame" function, the output/response frame is gone, I can't see it in the Wireshark. I've checked the pinout configuration for the Ethernet peripheral and the configuration addresses. I really don't know what I’m missing.
I've got auto-negotiation enabled in ETH CubeMX and I've change the PHY address from default 1 to 0 and PHY Link down inturrupt from 0xB to 0x10 according to datasheet (I hope it's correct).
Below I pasted my configuration for Ethernet PHY (LAN8742A):
