Sorry for my bad english
Hi.
I use STM32H743ZI and develop firmware.
I put an example of a lwip tcp echoserver in my firmware.
Example: STM32H743ZI-EVAL lwip tcp echoserver application
I'm not using RTOS.
My question: Ethernet operation relies on build optimization
Low level option inoperative ex> ping and connection
Advanced option is working
Can you explain why?
