STM32CUBEMX MODIFIED NOT WORKING

[prathima]

Hell Guys.....

I am working on STM32L4R9AI-EVAL board I have generated the project from Touchgfx Designer and it generating the STM32CUBEMX code also......if i open the designer and if i will burn on to the kit it is working fine....But once i will open STM32CUBEMX of the project and i will generate the code and again i will burn on to the kit this time i can able to download on to the board successfully but the dispaly seems to be off..I can't able to get anything...like previously...why?

Thank you

And one more thing if i open the keil compiler and compile it but am not getting any errors but warnings am getting "like

Empty execution description for region of Rw buffer" with this i can't able to load code on to the board.....

Thank you...

Linker complains that it can't get closure due to missing/undefined symbols.

Will need to add source files, or libraries, containing missing functions for build to complete successfully.​

But why it is not working........When i open STM32CUBEMX if i will generate code ...it is not working

Hello...I want to make the STM32L4R9AI-EVAL board work through STM32CUBEMX do you have any Example project?....if you have can you please share it to me.....I am trying to make it work but i have failed:|

Thank you

The undefined symbols are referred from bitmapdatabase.o, which is the object of bitmapdatabase.cpp. I don't think that's a Cube file. Maybe it's a Touchgfx Designer file? If so, you're posting to the STM32 MCUs topic and maybe not many developers there know about it. You can add topics using the little down-arrow in the top right corner of your post.

Google found https://github.com/STMicroelectronics/STM32CubeF4/blob/master/Projects/STM32469I_EVAL/Demonstrations/TouchGFX/Gui/generated/images/src/BitmapDatabase.cpp. Maybe something there will help?

But if am running through touchGfx Designer am not getting any errors....It is loading successfully but the display itself not switching on.....if i generate code through STM32CUBEMX...why?

[alister]

What is the IDE? I always diff and fix the project files following a a Cube generate. Check for folders/files removed or excluded.

[prathima]

The IDE is MRK-IAR (keil)

As we are generating from cubemx it won't includes BSP files, so i have added BSP files also Still it is not working...If i use IAR am not getting any errors ,but again loading is done successfully,, But i can't sea anything on the screen the display itself swiched off...why?

Thank you.
