Hello, I would like to connected my STM32F746G Disco board to the server on PC computer. I started from example from STM32CubeMX. I would like to do something like that:
PC computer as server - I using Hescules Setup Utility.
STM32F746NG - Disco as client LwIP no RTOS.
My issues is that I cannot connect to the server.
Please find in the attachment my firmware and raport from wireshark.
I tried the solution from:
https://community.st.com/s/question/0D50X00009XkgffSAB/stm32f746-ethernet-dma-transmit-problem?t=1639776494585
But doesn't work for me.
Ping from PC to STM32 work(<1ms).

I noticed that during trying connection with server(Hercules) if I switch the tab in Hercules application to "TCP client" and click connect and return to TCP server I got connection and then I can even reset the STM32 board and I can connect to the server until I close Hercules. It seems weird but it's the only way I've found so far to connect.
I will just add that if I use the STM32Disco as server and PC as client it work fine, the same with UDP.
What am I doing wrong?
Thank you for all hint and information.
