CubeMX 4.25 + STemWin + FREERTOS = bug

I made a project for CubeMX 4.25 + STemWin with 746Discovery (default config setting from CubeMX).

Everythingis well. (Keil 5.25 compiler)

I add FREERTOS to project (1 task with default setting)

After compiling I have error

linking...

746\7axf: Error: L6218E: Undefined symbol OS_TimeMS (referred from stemwin_wrapper.o).

Searching for 'OS_TimeMS'...

A similar situation for F4..

Hello

Chernobay.Vitali.002

,

Please, make sure that your project contains all the required library source files.

Have you copiedthe

fileGUI_X.c?

You should copy the

GUI_X.c file

$Library_path\STM32Cube_FW_F7_V1.0\Middlewares\ST\STemWin\OS\GUI_X.c

to folder

‘\Src’

in root of your project.

Hope this helps you.

With Regards,

Imen

Imen,

Thank you for attention.

CubeMX have to add GUI_X_OS.c to project with FREERTOS and delete GUI_X.c from a project

It is my no RTOS project

IT is FREERTOS project

For no RTOS project

For FREERTOS project

Searching for 'OS_TimeMS'...

Probably the OS_TimeMS generated by CubeMX needs to be removed from FREERTOS project?

solution of bug

in file ..........STemWin\Target\STemwin_wrapper.c comment

line (85):

//extern volatile GUI_TIMER_TIME OS_TimeMS;

line (876) :

// OS_TimeMS++;

It is work OK.

OS_TimeMS it is variable from GUI_X.c

You use GUI_X_OS.c

In attach working example

What exactly does not work?

Publish your project.

I did like the instruction in this topic: 

https://community.st.com/0D50X00009XkXi3SAF

 

The screen was black with a bar full of multiple colors, the project link is here:

Thank you very much

Try inrease stack size in CubeMX (example from 0x400 to 0x4000)

and correct file   STewin_wrapper.c

void GRAPHICS_Init(void)

{ /* Initialize the GUI */ GUI_Init()

WM_MULTIBUF_Enable(1)

/* Enable the multi-buffering functionality */

/* Activate the use of memory device feature */

/* USER CODE BEGIN WM_SetCreateFlags */ HAL_LTDC_ProgramLineEvent(&amphltdc, 0) //!!!!!!!!!!!!!!!!!!!!!!!!MULTIBUF WM_SetCreateFlags(WM_CF_MEMDEV) /* USER CODE END WM_SetCreateFlags */}
