Downloaded FreeRTOS and the GCC just a couple of minutes ago so they should be "fresh"…

Looked at line 77 in led.c were the errors are reported. I never even seen code like that so that didn’t help me much.

Any ideas as to what goes wrong here?

Take a look at this thread: [https://sourceforge.net/forum/forum.php?thread\_id=2636701&forum\_id=382005](https://sourceforge.net/forum/forum.php?thread_id=2636701&forum_id=382005) in particular the bit about the Atmel Software Framework.&nbsp; I need to contact Atmel about this, it seems they may have changed some register names in the header files.

Regards.
