Hello,
I have a problem with stm32cubeide6.1 and xcubetouchgfx 4.16.1. It generates error when I build the project. I send the errors and my project in attached file.
Hello,
I have a problem with stm32cubeide6.1 and xcubetouchgfx 4.16.1. It generates error when I build the project. I send the errors and my project in attached file.
Downloading your project file I notice that the project is a "C" project. Not a C++ project. Maybe you initially created it as a C project?
You can convert it into a C++ project and all settings from the C Compiler/Linker will be copied/migrated to the corresponding C++ tools.
Right-click on the project > Convert to C++
After doing that, and opening TGFX Designer 4.16.1 and clicking generate, I have all the files needed to successfully compile the project.
But the linking fails since the TouchGFX_Framebuffer needs 750KB RAM and the device only has 320KB...
So, I assume you have to also modify the size of this frame buffer (rely on partial frame buffers, or rely on external RAM depending on what performance you need). I by-passed it by modifying the linker script to set :
RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 1024K
Only to validate that the project could build successfully. I can of course not run this code... =)
Are you using the RAM linker script to build the application instead of the FLASH?
Looking at the project you uploaded you are relying on the flash variant (STM32F469NIHX_FLASH.ld)...
Do you have external memories? If so your application must initialize those memories....
The application could work as intended when debugging because the debugger would first initalize the external memory using a flash loader file. But if you later power off/on the board then your application code must perform the same initialization.
Those are the two main sources that could lead to this new found issue (that I can think of right now).
I have tried another thing to make my project work. I've started a project with touchgfx by selecting stm32f469i-disco board. Then I modify the cubeide to have analog value display on the screen. To do that I have added a task and a semaphore on touchgfx task. I have tried to add .h and .c files on the project but it didn't work so I have deleted the files. Next I choosed to put all my functions on the main file. When I compile the project I have no errors but touchgfx Interactions doesn't work. I send you my new project in attached file. Could you please check it ?
