    Only crash log will not help here, you may want to describe, in what condition you are getting these kernel crashed? Any command? Any scenario, when it occurs? Does it happen during boot itself?

    Also, Have you checked your DDR configuration? I would suggest you to run memtest from u-boot prompt.

    Thanks,

    Vaibhav

    Dear Vaibhav,


    what condition you are getting these kernel crashed? Any command? Any scenario, when it occurs? Does it happen during boot itself?

    some time boot itself and while mounting rootfs in case of android rootfs.

    Have you checked your DDR configuration?

    with armstrong roofs it's mounting. so is it DDR configuration problem?

    i have tried mtest in u-boot prompt ,but it's not at all terminating it's been looping continuously.

    thanks in advance
