[youssef.amimi]

I running an application on STM32F769 with EWARM that connect to Servers from the net and receiving data (with Net Thread) . Next i added all necessery files and a graphic Thread in main file to display the data on th lcd when i pressed on a button . When i run the application the lcd works and the button appear but the Net Thread blocked on the instruction ( MX_LWIP_Init();)

PS: when i comment the instruction GRAPHICS_Init(); the board connect to the Net

Hi @youssef.amimi​,

I'll try to think about what's wrong here. I'm not that familar with lwip + TouchGFX, but we have a few projects here that we did a while back. The LWIP stack in CubeFW does have it's own issues, so iI'll have to get back to you, is that allright?

Best regards,

Martin

Hi @Martin KJELDSEN​ 

The problem is that I choose TIM1 as a timebase source, this timer is used in STM32F7Instrumentation::init. I change the timebase from TIM1 to TIM6 and it work.

Thank you @Martin KJELDSEN​ for your assistant.
