I thought that was not possible to run Linux on my AT32UC, but I read this in the AT32 UC3 FAQ in ATmel website:
"
Question:
Is the UC3 family able to run linux?
Answer:
As quick answer we should say no as the UC3 devices do not embed any MMU. However since the latest version of the Linux kernel allow usage of processor without MMU, it becomes possible to support Linux.
"
So, has anybody executed Linux in this AVR32 family? If the answer is "yes" where can I find information about how to do it? I've looked for in this forum but haven't been able to find information. Maybe I havent searched properly.
Thanks! |

Sorry, the precise question should have been: " has anybody executed Linux in this AVR32 - UC3 family? " I know that at this moment Linux is only availabe for the AP7x family, but as I posted, this note in ATmel's website says :
"

So, teorically should be possible to execute it in the AV32-UC3, but: has anybody done it? |

Sorry! I didn't see the first words!
Is anybody working on the porting of this new Linux kernel to AT32 UC3 ? I think that uC-Linux does not need an MMU, but I haven't found any porting to AT32 UC3. It should be very nice to at have, at least, uc-Linux runing on AT32 UC3.
Is there any other recomended free multitasking OS for this uC, a part from FreeRTOS ? |

AFAIK, there is no port for uclinux for AVR32 (You could initiate the port  ).
As you know, FreeRTOS is already ported for the UC3 and available in the framework. Any reasons for not using it.
There was some discussion in the AVR32 Standalone forum about an on-going port for Ethernut. You could search the forum for more details and the status of the project. There are some commercial RTOS available for the AVR32. I am not sure which ones, you could use google or check atmel.com.avr32.

Hello everyone,

| AFAIK there has been no progress since the wiki pages on avr32linux.org was made. I've not seen any new patches to either uClibc or the Linux kernel itself. No changes to the toolchain either to generate the convenient position independent binaries. |

oh
I didn't know that.
Does that mean we use another FreeRTOS? another firmware concept? |

On the UC3 devices you can run fine without any RTOS, or you can pick FreeRTOS, ThreadX, etc. if you want a scheduler made for you. If you don't need pre-emptiveness, then it isn't rocket science to implement a scheduler on your own.
For UC3 you also have a lot of example code in both AVR32 Studio and AVR Studio 5. |
