Compilation error with TouchGFX application

[AnchalS]

Title modified by an ST moderator to be inline with the content.

My goal is to establish CAN communication between Riverdi display - RVT50HQSFWA01 and my laptop. After developing a test GUI using TouchGFX 4.26.0, when I added the code patch for CAN communication then I keep on getting various build errors due to comaptibility issue between TouchGFX and STM32Cube IDE packages. If anyone has tested CAN communication for Riverdi Display boards that can help then kindly reply. I have been trying to get this done for quite sometime now and have been stuck at what seemed like a very simple task.

 

For the sake of reference, the latest build error is :

make: *** No rule to make target 'C:/TouchGFXProjects/LIB_display_1/TouchGFX/target/CortexMMCUInstrumentation.cpp', needed by 'Application/User/TouchGFX/target/CortexMMCUInstrumentation.o'. Stop.
make: *** Waiting for unfinished jobs....
"make -j22 all" terminated with exit code 2. Build might be incomplete.

The build error not at all related to CAN, thus the thread title is a bit misleading.

You would need to sort this TouchGfx error(s) out first.
I'm not an expert with that, though.

You will need a CAN dongle (e.g. CAN-USB) adapter for that, which must not be in listening-only mode.
I would suggest to look at CAN examples for your MCU, and add the relevant code to your application.

Hello @AnchalS and welcome to the ST community,

That issue is more related to TouchGFX than to CAN communication.

So this post will be moved to TouchGFX forum board.

If you have questions on CAN communication, you need to ask that question in STM32 MCUs Products forum board and remove all middleware unrelated to the CAN communication: TouchGFX, FreeRTOS etc ..

Hi,

My end goal is to interface a Display module (RVT50HQSFWA01) with my laptop using CAN communication. I developed a very simple GUI on Touch GFX Designer 4.25.0 where a variable is updated in real-time, and tested that on the simulator, it is working as expected. Now when I try to build the project in STM32Cube IDE 1.19.0, then I get the following build error. I have set the OS mode as No OS in the .ioc file in TouchGFX Designer also properly. But still while building the project I am getting this error. 

Build error : 

make: *** No rule to make target 'C:/TouchGFXProjects_4_25/LIB_display_2/TouchGFX/target/generated/OSWrappers.cpp', needed by 'Application/User/TouchGFX/target/generated/OSWrappers.o'. Stop.
make: *** Waiting for unfinished jobs....
"make -j22 all" terminated with exit code 2. Build might be incomplete.

19:32:27 Build Failed. 2 errors, 0 warnings. (took 4s.216ms)

If you have any suggestions related to this, then please reply to the post
