PROCESSOR-SDK-AM335X: NOR flags resetting to default

Hi,

    We checking in Nor Flash { m25p16 } interfaced am335x board series, used to set & get from nor environment flag using this command nor_getenv, nor_setenv.

     setting values { nor_setenv } in nor flags, After reboot, We are getting { nor_getenv } nor environment flag correctly. 

    & After we are not getting set environment flag due to facing couple of power dips/failures . Nor flags are resetting to default.

    Please resolve my issue we are facing " Nor flags are resetting to default due to facing couple of power dips/failures"

Starting with the following flags:
nor_setenv 0 1 1
nor_setenv 0 2 4
nor_setenv 0 3 4
nor_setenv 0 4 2
nor_setenv 0 5 0

nor_setenv 1 1 1
nor_setenv 1 2 4
nor_setenv 1 3 4
nor_setenv 1 4 2
nor_setenv 1 5 0

nor_setenv 3 1 1
nor_setenv 3 2 4
nor_setenv 3 3 4
nor_setenv 3 4 2
nor_setenv 3 5 0

nor_setsig 1

And then rebooting the board, after a couple of power failures in the MLO/u-boot, the NOR settings are reset to default:
