STM32F746 LWIP + FreeRTOS CMSIS V2

[marcinq]

Hi,

I'm using an STM32F746G-DISCO board and I'm just trying to build a build a simple project with LWIP and FreeRTOS using CMSIS V2 however after enabling the minimum hardware using CubeMX I am unable to get any ping replies from the board. If I use CMSIS V1 for the config, then the board responds with ping.

The reason why I want to get this working with V2 is that I'm planning to use TouchGFX in my project and when creating project using the TouchGFX, it defaults to CMSIS V2 and I've not seen any option to change that. I've tried generating project using TouchGFX and then changing it using CubeMX to CMSIS V1 however then the project falls apart and it seems like HAL_Delay which is used in some of the initialisation functions stops working.

I'm using CubeIDE 1.16.0.

Attaching the project for reference.
