STM32H755ZI-Q: LAN8742,problem with ping after dhcp server gives ip address to the nucleo-board.All set-up made by example for STM32H745ZI-Q
Hi
I am trying to make simple setup for H755ZI-Q nucleo-board with ETH + LWIP + RTOS. I was using this Forum Section as the source of example that i used (H745ZI-Q) that is by all documents have same characteristics as my board and compatible with it .
So back to the Problem, my board doesn^t respond to ping that i send even when the dhcp server that i started on my PC gives me that the board on this “IP-address” . After what the ping don^t go through. I added a breakpoint to "void ETH_IRQHandler(void)". After the initial power-on, the system reaches the breakpoint three times even when there is no ping command on the Ethernet port. Can u please help me with that?
I tried to reconfigure everything from flash memory , turn off the Cache to check if that change anything , I have even Hybrid of RTOS + Raw Api ETH + LWIP that works. I could not understand is smth wrong with my board or with code that generates cause in Documents everything sounded simplier.
