Re: gRT->SetVariable ACCESS DENIED error

[Toan Le manh <lemanhtoantb@gmail.com>]

Hi Andrew,

I'm trying to set some variables to NVRAM at the beginning of BDS phase.
For example, this function returned EFI_ACCESS_DENIED
    Status = gRT->SetVariable (
                    L"HwErrRecSupport",
                    &gEfiGlobalVariableGuid,
                    EFI_VARIABLE_BOOTSERVICE_ACCESS |
EFI_VARIABLE_RUNTIME_ACCESS | EFI_VARIABLE_NON_VOLATILE,
                    sizeof (UINT16),
                    &HardwareErrorRecordLevel
                    );

Thanks & BRs,
Toan
