Port QNX to ARC

Hello,

I’m currently evaluating RTOS platforms for an embedded system that
utilizies an ARC processor. I understand that QNX does not support the ARC
processor. How easy does the QNX platform make implementing a custom HAL?
Do I even want to consider QNX or should I look at RTOS solutions
specifically for the ARC.

I’m thinking about QNX mainly because of some of the higher level support
you get out of the box. If it is possible to implement a custom HAL my
question becomes is it easier to develop a HAL or is it easier to
reimplement the other pieces I need for some other RTOS.

Thanks in advance.

It looks like the ARC doesn’t have an MMU. Unfortunately, this is a very
basic requirement of our OS so it looks like we wouldn’t be able to run on
that CPU. Sorry. I think, however, that if your project could consider
using something like an Arm or SH4, you would probably find that the ease of
development and power of our platform would give a strong incentive. Take a
look at http://www.qnx.com/resource/rs_evaluation/ to see some interesting
comparisons between our OS and some of our competitors.

cheers,

Kris

The chip we are developing for has an ARC core so there isn’t anyway to
change it. Thanks for your help.
