How many threads does RTEMS create?

2020-12-27 Thread Richi Dubey 
Hi,

When I am debugging the tm24 running on Strong APA scheduler, I can see
that when the Tasks

function is being executed, there are two threads with priority 2, with
status SCHEDULER_SMP_NODE_BLOCKED in the list of threads, with both of them
having different addresses. How can there be two such threads?  Shouldn't
there only be a single thread with priority 2 that runs the High_task

function? Please let me know your views about this.



Thank you,
Richi.

I have a problem with the patches on a non-fdt-BSP: The test doesn't
link. I tried it with the xilinx_zynq_a9_qemu BSP.


Basically the bsp_fdt_get() is missing on that BSP. To work arround
that, it is possible to change the return statement in the
__wrap_bsp_fdt_get to:


      #ifdef BSP_FDT_IS_SUPPORTED
        return __real_bsp_fdt_get();
      #else
       return some_bin;
      #endif

I am sorry for not testing it on a non-fdt-BSP, I totally forgot about 
this part though

you mentioned it in the previous patch.

Note that in the no-fdt-bsp-case, it has to return a valid FDT because
otherwise the ofw initialization fails.

I tested that modified version on xilinx_zynq_a9_qemu and on BBB and it
seems to work fine. If you are OK with this modification (and no one
objects in the next two days) I'll push the patches with this
modification.


Please push if no one objects.

Thanks. It wouldn't be reasonable to travel during a pandemic and I
don't like traveling anyway.

+1

Therefore it's a quiet and relaxing
vacation ;-)


:)


Thanks,
Niteesh.
