Hello,
The company I work for is currently using AURIX/TriCore
micro-controllers running PXROS as real time operating system.
I am now investigating if we could use a free alternative like RTEMS
instead. However, from what i've seen so far (I'm very new to RTEMS)
the TriCore architecture is not supported by RTEMS.
Would it be possible to run rtems on an aurix micro-controller?
yes, there is currently no TriCore support for RTEMS. One of the reasons
is that there is no free and maintained compiler available for this
platform (at least as far as I know).
What would have to be done to support a new processor architecture?
Firstly, you need a compiler. Ideally one which can build Newlib. For
the RTEMS core, you don't need a full C library, but if you can't use
Newlib, then things get more complicated. Then you have to do a full CPU
port for the TriCore. This is feasible, but not done in two weeks of work.
