Assign Static IP address in Threadx

[PG.9]

Greetings !

I am working on STM32H743 EVK and I could successfully compiled and executed the sample TCP Echo Server application over Threadx .

But here DHCP IP is assigning . Please help me out to make IP as static IP.

Thanks in Advance

Hi,

If you are using STM32CubeMX to generate project, you need just to disable the "Addons DHCP client" component and regenerate your project or you can disable DHCP manually and define your static address in app_netxduo.h:

#define NX_APP_DEFAULT_IP_ADDRESS          IP_ADDRESS(192, 168, 1, 1)

#define NX_APP_DEFAULT_NET_MASK           IP_ADDRESS(255, 255, 255, 0)

Hi ,

Thanks for the valid information . Now I could able to assign Static IP .

But here I am facing issues with it . Most of the times Ethernet is assigning the IP only when I remove and reinsert the network cable (proper Network cable is used).

Can you please help me out to overcome this issue . Below mentioned is my "App_Link_Thread_Entry" function .

Thanks in Advance
