Hi, I used to FreeRTOS V 7.3 (this is included in ASF by in Atmel studio) for my ARM SAM4S. I want to use FreeRTOS V 8.xx, but this version is not yet available in Atmel studio by ASF, so I downloaded newer vesrion from official pages. But after implementation and complinig I have many errors. I absoluttely do not know where I have a mistake, Could you help me please? My project is blank - no code, just only implementation of FreeRTOS. I have about 130 errors.. it is like: Error unknown type name 'UBaseTypet' Quadro32FreeRTOS_8

Thanky ou very much for support.

UBaseTypet is a FreeRTOS type, and if you have the header files included correctly it will be found. I don't know what Quadro32FreeRTOS_8 is, it is not something from the FreeRTOS distribution.

You will find some information here: http://www.freertos.org/Creating-a-new-FreeRTOS-project.html http://www.freertos.org/porting-a-freertos-demo-to-different-hardware.html

...but I would recommend just starting with one of the Atmel Studio projects from the FreeRTOS distribution: http://www.freertos.org/a00090.html#ATMEL or simply copying the latest FreeRTOS source files over the top of the older source files in the auto-generated project.

Regards.
