is the Atmel AT32UC 3C supported in freeRTOS?

Question

I have an Atmel AT32UC 3C which I want to use. I'm just getting started with freeRTOS. I'm using Eclipse IDE along with MingW gcc compiler, and I downloaded FreeRTOS v8.2.3, v9.0.0 and v10.2.1. The problem is I can't find a demo example for AT32UC 3C; only AT 32UC 3A and 3B are available. Am I missing sth??

Answer 1

Looking at the listed ports on the freeRTOS website, AVR32 UC3 is supported. If you follow the Atmel link on the previous page, there is this disclaimer:

These demos can be adapted to any microcontroller within the same family that has sufficient ROM/RAM. See the Creating a new application and Adapting a Demo pages.

You can find an example there (this is not the official website anymore).

Answer 2

The only key difference between UC3A and UC3C is UC3C has an FPU. It will run fine.

Answer 3

THe AVR32 port shipped with FreeRTOS was written for original AVR32 chips and has some known issues when run on the latest chips - therefore recommend using the FreeRTOS AVR32 port that ships with Atmel Studio itself.
