FreeRTOS on STM32U5G9ZJT6QU

[MichaelZ22]

Hi. I am working on creating parallel threads on my STM32U5G9J-DK2 board using freeRTOS. Are there any freeRTOS example projects for this devkit I can reference? I could not find any while creating a project in the STM32 Cube IDE.

Thanks, Michael

Hello @MichaelZ22, welcome to ST Community, 

There is no specific FreeRTOS example on STM32U5G9J-DK, there are applications for ThreadX in the STM32CubeU5 repo. 

But using stm32CubeMx, it shouldn't be complicated

Hello,

I was wondering if it is possible to use the FreeRTOS Middleware which is used on the STM32H7 and STM32F4 and which can be found at the following links ‘https://github.com/STMicroelectronics/STM32CubeH7/tree/master/Middlewares/Third_Party/FreeRTOS/Source’ and ‘https://github.com/STMicroelectronics/STM32CubeF4/tree/master/Middlewares/Third_Party/FreeRTOS/Source’ in the case of the STM32U5G9. Or if on the other hand, in the case of this chip this Middleware is not valid and it is necessary to proceed in a different way.

Thanks!

Hi Michael,

I found some code that might be useful, so I’m sharing a link of it with you. However, we’re also facing an issue with the same board, specifically with USB CDC-ACM functionality. The USB connection isn’t showing up in the Device Manager—only the ST-Link cable appears, not the application USB cable. I suspect it might be a driver issue on my end.

I’m attaching my code as well. If you could take a look and maybe suggest what might be missing or needs adjustment to activate the USB, it would be a big help.

Thanks in advance for any guidance you can offer!
