We are also using the GR712RC and its multiprocessing capability.

We've found the "Multiprocessing" section of this document quite useful:


The "MP testsuite" included in the Gaisler provided RTEMS source tree has been helpful as well.

Hello all,

We are planning on working with a LEON3 processor soon (Aeroflex GR712) and I was investigating how the dual core aspect was handled in RTEMS.

I found this page : http://www.rtems.org/wiki/index.php/SMP however it seems to be severely out of date while mentionning that SMP is now implemented for the LEON3 BSP.

The LEON3 BSP page does not give a lot of information either (

Is RTEMS entirely handling the multi processor aspect or do the user have to do anything?
Where can I have more information about the multi processor aspect of RTEMS and how to handle it?

Thanks in advance!
