Dear Huber, I am sorry for wrong information.
Please disregard previous question. As I checked in many times, there is CPU0's S/W blocking case before using rtems-libbsd. That is, there is not rtems-libbsd. Anyway, I will try to test my SMP code using i.MX7D board next week.

Dear Huber, Thank you very much. I was successful to booting RTEMS on i.MX6Q SDP board according to your guide. I have very interesting problem for testing rtems-libbsd on i.MX6Q. At this time, I am testing SMP with rtems-libbsd. When I test SMP example without rtems-libbsd(that is, calling rtems_bsd_initialize, network_ifconfig_xxx), SMP example is working very well. But, When I test SMP example with rtems-libbsd for calling rtems_bsd_initialize, S/W is stopped. When I check current S/W location using GDB/JTAG, Clock_isr() is still called by timer interupt. Also, _CPU_Thread_Idle_body() is running. I guess that there is S/W blocking condition for calling rtems-libbsd API. I don't know reason. Anyway, I purchased i.MX7D board in today. Maybe, I can test same SMP example on both boards(i.MX7D and i.MX6Q) next week. If I have similar problem on i.MX7D, I will let you know that.
