Hello all,
I'm from Embedded Systems Bare-Metal Ethernet Programming course. In topic "Developing HTTP Ethernet Applications -> Programming Detecting Link Change", I found that problem about clock configuring may cause application display message "Cable connected" even if it's not connect. Then, I try to configure and debug about clock configuration but problem still occur.

Can you suggest me about some point that I miss or I should check.
**Note
1. I use STM32F746GDISCOVERY Board (not the same in video)
2.I use USART6 to send message to Arduino UNO R3 to see message.
3.My project source code is here, you can check or can upload to your board.

Thank you very much

Hello All, I came to know in the course Embedded Systems Bare-Metal Ethernet Programming last video related to STM32 as TCP Client is not uploaded yet, I am asking this because after completing the last session i.e STM32 as TCP client I am facing an hard fault issue.
tcp_client->p = pbuf_alloc(PBUF_TRANSPORT,buff_len,PBUF_POOL.

Thank you TeachingAssistant, I try follow same code in the course and I found that if I put this code in while loop(main.c)

ethernetif_set_link(&gnetif);

it will loop checking connect/disconnect the cable.
So, it is what I desire now.

Thank you

Hi,
just follow the same code in the course.
It will work just fine since the core is the same and the ethernet controller is the same also.
Try the code in the source code section.
