Hi,
I am new to MC9S12XD processor and would like to get some recommendations about which RTOS I can use with  this processor. I heard of OSEKTurbo and CMX. Does any one  have a  comparison of them?  And  any  free  RTOS?

[JimDon]

Well, there is freertos at http://www.freertos.org/.
That is the only completely free one. You can buy a certified version of it.

Theres is ucos-II at http://www.micrium.com/
Which is free until you start to sell your product.
Both of there have HCS12 ports.

If this is for a commercial product, you probably want buy something so that you don't spend your dev time debugging the RTOS, it's not worth it. Both ucos and freertos have pretty good pricing.

Jim,

Thanks for your reply. I will take a look at the free ones and see what I can get from them.

Thanks again,

Julie

You will probably have to take a port that is close and adapt it to your particlular chip, which is what I did.
If you need some help, just ask. I ported them, then didn't do much with them (yet!).
Here is a link to a port to Dragon12 (scroll down the page) of freertos.
I haven't tried this one, but I've been meaning to when I get some time.
The code on this site is usually very good.

The Dragon12 has a D series (Not XD -DP or DG) which should be pretty close.
For ucosII there was a CW port for the NE64 which I adapted to dragon12.
