Hi,

It was created on top of an old ChibiOS version, things have changed in 3 years and probably something has be be adjusted.

Your best option is to get in touch with the author.

Ok, I will try to get in touch with him.

But what with include ChibiOS/HAL files to FreeRTOS? Errors in build may be caused by too old version osal?

Hello,

I took another stab at making the OSAL for FreeRTOS. There are still some things unimplemented but for the most part it seems to work well. Compared to the last one, it doesn't use thread events so you can use those in your application. It also has the threads queue implemented.

It was made for ARM Cortex-M, so if you are using a different arch you need to adjust some things.

I have only tested with the SD, GPT, and ICU drivers.

Make sure configUSE_TICK_HOOK is set to 1 in your FreeRTOSConfig.h, the osal defines vApplicationTickHook to clock virtual timers.

Hi,

Thanks for the code.

Do you have some kind of demo application for STM32? potential users would appreciate a starting point.

Actually I used the CMSIS wrapper for FreeRTOS found here. So the demo in STM32/CMSIS-STM32F407-DISCOVERY will work as is. But the wrapper is not very efficient... it adds a lot to the text segment. I will try to get a demo going using only the FreeRTOS API.
