TCP network communication problem

TCP network communication problem [Copy link]

I used STM32F767 to write a network communication program, TCP protocol. I used the development board routine. But the host and slave computers cannot connect. I simulated and debugged and found that as shown in the figure: When I single-step in the memory application, an error occurs. Please give me some advice, thank you!

Go into pbuf_alloc and take a look

pbuf_alloc comes out of this function. No problem, but it comes here again, so strange

Then I walked and ran here again.

Then it returns to the original function. It feels like an endless loop here.
