How to generate udp_echoclient.c in STM32 H743

Hi

I'm trying to implement STM32 F429 code into STM32 H743.

The previous code works fine, so I'm trying the code in STM32 H743 as well.

I mimic most of settings, but failed to generate udp_echoclient.c file.

Can somebody help me out with this?

Thank you in advance.
