Hi.
I'm trying a simple ping application with my board that contains the H743 microcontroller. I am following the instructions in Adam Berlinger's example. But I can't get ping. I connect my computer to my board via ethernet switch. My computer's IP is 192.168.2.5. But it can't reach to my board. When I try to send UDP packet, I can see the Ip adresses of target and destination(via WireShark software). But I can't see the "Hello UDP message!\n\r". IPs are manually setted. H7 board and computer connected via ethernet switch hub. I added a breakpoint to "void ETH_IRQHandler(void)". After the initial power-on, the system reaches the breakpoint twice even when there is no ping command on the Ethernet port. But when i send ping commands, nothing happens. I can reset LAN8742A PHY via GPIO.

HAL_Delay(50);

HAL_Delay(100);
