ChibiOS/(NIL & RT) support for AVR XMega

Postby tfAteba » Wed Aug 09, 2017 10:02 pm

Hello every body,

I started the port of ChibiOS on the AVR XMega architecture.

The port is not yet finished for the moment. There are still a lot of driver to write :D .

I made some commit to the trunk to add the following features:
    - System tick low level driver files, for the moment, just the periodic mode is implemented.
    - PAL low level driver files.
    - Board files, for the Maittair Tech MTAVR XMega128a4u USB development board (MT-DB-X4).
    - Nil demo for the MT-DB-X4 board, the demo just toggle the onboard Led every second.

That all for the moment, I will regularly post about improvements.

Thanks.
regards,

Theo.

Hi.
I made it 4 years ago :) And somebody also did it too. There is no big interest for it. AVR cost much and still 8 bit. Also I had some strange problems which i can't solved.

Hi Alexblack,

Thanks for your point of view. I sow your post some time ago.

I made it 4 years ago :) And somebody also did it too. There is no big interest for it.

I made this port to learn how ChibiOS work, and also to write some drivers while making a port.
So for me there is a lot of interest :D, I also think that it will be interesting and benefit for other people.

As you said you had some problems that you can't solve, I will see if I will have the same problem. If it is the case hope to solve it but for the moment I just started :lol: .

The price for me is not important, because I just do that for fun and do not want to build a lot of products for example.
regards,

Theo.

Hi all,

Just want to said that I added another demo. This time, it is a demo that runs ChibiOS/RT. It simply toggle an LED for the moment.

All demos added for the ATXMega can be found under trunk/demo/AVR/

Thanks.
regards,

Theo.
