NUCLEO-H743ZI2 lwIP TCP Connection

[NDalv.1]

How can I establish a TCP Connection with an NUCLEO-H743ZI2 ?

I managed to establish a simple TCP Connection with a NUCLEO-F429ZI and my PC using the lwIP stack (without FreeRTOS). The NUCLEO-F429ZI was the client and connected to a server, which was running on my pc using hercules. This worked without any problems. Now I tried to use a NUCLEO-H743ZI2 instead, because I needed more RAM for my application. I implemented basically the same application but the tcp connection is never established. After calling 

tcp_connect(...)

 the callback is never called.

I tried multiple different firmwares and configurations but nothing worked for me.

I also tried with same linker file and mpu configuration but it is not working.

please guide me about this issue. your immediate response is really helpfull

Compared to H7, you would have a better luck with F7, which still has more RAM. But anyway - ST doesn't provide a working network implementation.

Do you mean tcp/ip will not work properly on H7 Series. As i compared with F7 series example code almost all code in main source file is same.

Is there memory issue with H7 while using tcp echo client example code.
