Re: [ts-7000] Linux with custom RTOS

[Gary Wicker <>]

Hi Fred,

You might be better off porting the app running on the custom RTOS to RTLinux.  This would probably be a lot easier.

There would be many issues with running linux as a task under your custom RTOS; not only with interrupts but also with virtual/physical addresing, MMU, page tables, etc...

Hi All,

Got an interesting question for you all.  At my work we have a custom
RTOS that's used for motor control.  One of our contractors is going
to port this to the ARM CPU.  What would be involved in getting Linux
to co-exist with a custom RTOS?  Would it theoretically be as "simple"
as running Linux as a background thread and forwarding the various
interrupts it needs for device drivers to the Linux thread?  I know
this could be a lot of work, was just wondering what the steps would
be.

Thanks,
Fred
