Dear all,

I'm facing the Status EFI_ACCESS_DENIED when using gRT->SetVariable()
method.
There is no description of this returned status for SetVariable()  in UEFI
spec.
Have you ever faced this type of error? Could you please give me any idea
on how this happen?
Sorry for any inconvenience, I'm newbie in EDK2.

Thanks & Best Regards,
Toan
