CMSIS_V2 causes "No rule to make target" error when used with ETH + LwIP

[FabianEbs]

I am trying to implement MODBUS-TCP on a TouchGFX generated project. I have successfully enabled Ethernet by following this tutorial on this forum: How to create a project for STM32H7 with Ethernet and LwIP stack working and can ping my board.

In the tutorial mentioned above CMSIS_V1 is used, but for the MODBUS library which I want to use CMSIS_V2 is required ( Modbus-STM32-HAL-FreeRTOS ).

Now if I simply change CMSIS to V2, i get the error: 

make: *** No rule to make target '.../Ethernet_Test_TGFX/Middlewares/Third_Party/FreeRTOS/Source/CMSIS_RTOS/cmsis_os.c', needed by 'Middlewares/FreeRTOS/cmsis_os.o'. Stop.

Is this caused by dependencies not being updated properly or how can I solve this? I already tried Refresh+Clean.

.ioc file is attached.

Thanks!

cmsis_os.c is for CMSIS_V1, you need to use cmsis_os2.c and port your CMSIS V1 to CMSIS V2

Thanks for the reply!

The error was caused by setting CMSIS setting from V1 to V2 in CubeMX, so i need to change something else, but what and where?

As I don't have your TouchGFX project I cannot test it but you can remove cmsis_os.c from the project tree. 

cmsis_os2.c is already added..

Yeah, that did the trick, thanks a lot!
