Hi @asadullah4571 

LwIP Stack to support Ethernet on M33 is now released and several applications are also released for STM32MP257-EV1, STM32MP257-DK boards etc. for both Bare Metal and Free RTOS in the official release of STM32MP2 v1.3.0.

Hello @asadullah4571 ,
The LwIP stack to support Ethernet on M33 will comes in the next CubeFW release, in February 2026. It will be the same kind of stack you can find on CubeFW for STM32MP13 bare metal.

Kind regards,
Erwan.

@Erwan SZYMANSKI 
thanks for your quick response ,
I will wait for the firmware release.
I will work in Ethernet after releasing the cube MX.

so as of now,  I  want to test with M33, how to connect (stm32mp255DAK3 -custom board ).
how to toggle the LED's from the M33 co-processor. 

I saw there is prebuilt examples for the stm32mp257fdk or evk,  but how can i start with stm32mp255DAK3 -M33 co-processor ,
can you please guide me to do this work,
