Re: [Xenomai-core] Question on uITRON Skin development and porting to iMX27/ARM926EJ-S
Ravikiran Saralaya wrote: 1. The uITRON specification requires task creation to accept base address of task stack to be allocated. The xnarch_alloc_stack() currently accepts only stack size but not the base address. The solution is simple: let the system allocate the stack, or implement the missing functionality. I also tried to get different Linux kernel version ported to iMX27, such as 2.6.20, but I don?t have any option here other than 2.6.19 :( Then I am afraid there is nothing we can do for you.

Re: [Xenomai-core] Regarding enabling SMP with Xenomai
Thanks a lot Gilles, I used the Xenomai 2.4.8 version with a newer kernel 2.6.28.9 to be precise. Initially the kernel compilation gave error of NR_CPU flag, i lowered the no of CPUs to 16 and it worked. Now the xenomai is able to see two CPUs, the output of /proc/xenomai/sched is : CPU PIDPRI PERIOD TIMEOUTTIMEBASE STAT NAME 0 0 -1 0 0 masterR ROOT/0 1 0 -1 0 0 masterR ROOT/1 The output of dmesg |grep is [4.353912] I-pipe: Domain Xenomai registered.
