after enabling the rtos part of this project select in lv_conf.h (#define LV_USE_OS LV_OS_NONE to #define LV_USE_OS LV_OS_FREERTOS)

I have tried many times but couldn't solve this issue. During this process, I created an Ubuntu virtual machine as well as WSL2 on Windows.

@viys did you followed the instruction?
Could you describe how you setup the project?

[viys]

Recently, I noticed that you have made updates, but I encountered the following issues while compiling the project.
Here is the process of my setup project,



I won't be able to complete the compilation of the project this time.

Probably it's related to this: #65 (comment)

@viys Did you checked the CMake path, is it right?

@viys Did you checked the CMake path, is it right?

I directly cloned from the repository, modified it, and followed “To enable the rtos part of this project select in lv_conf.h #define LV_USE_OS LV_OS_NONE to #define LV_USE_OS LV_OS_FREERTOS. Additionally, you have to enable the compilation of all FreeRTOS files by turning on option(USE_FREERTOS "Enable FreeRTOS" OFF) in the CMakeLists.txt file.” to make the changes.😢

I have the same error as you, and has it been resolved?

I have the same issue with the segfault. The debugger gives this backtrace

xTaskGenericNotify(TaskHandle_t xTaskToNotify, UBaseType_t uxIndexToNotify, uint32_t ulValue, eNotifyAction eAction, uint32_t * pulPreviousNotificationValue) (.\lv_port_pc_vscode\FreeRTOS\tasks.c:7867)

The xTaskToNotify variable is null which is causing the segfault

[AndyEveritt]

Updating the lvgl and freertos submodules to release/v9.2 and main (974351fe4aec19779f5be774007810c6ab36a8ab) respectively fixes the segfault

@liamHowatt @uLipe could you take a look at this issue?

[uLipe]

Looks like the render thread was not created when the sw render executor wants to trigger it.

I will check that

[AndyEveritt]

@uLipe did you find a solution in the end?

[uLipe]

@AndyEveritt this is on my next tasks to handle, I will keep you posted.
