Thanks Yuri. We are using below Kernel Confiogurations for Quad sample but all cores are not probed. Only two cores are active. Please suggest in case of any missing configuration.

zcat /proc/config.gz | grep SMP

CONFIG_GENERIC_SMP_IDLE_THREAD=y

CONFIG_HAVE_SMP=y

CONFIG_SMP=y

CONFIG_SMP_ON_UP=y

CONFIG_PM_SLEEP_SMP=y

  By default number of cores are detected automatically and all cores are enabled, if kernel

command line does not contain special parameters, such as "nosmp" or "maxcpus".

Use Table 9 (Common kernel boot parameters) of i.MX_Linux_Release_Notes.pdf for details.

Regards,

Yuri.
