Hi All, I would like to know the updates on this issue. We also have a similar problem. One of our hardware does not have RTC. Is there any resolution made on this?

The UEFI BeagleBoard Firmware at this time did not have RTC support in UEFI. As Andrew said, the firmware was using EmbeddedPkg/RealTimeClockRuntimeDxe and its library EmbeddedPkg/Library/TemplateRealTimeClockLib to provide gEfiRealTimeClockArchProtocolGuid to pass the DXE core initialization. But we realized the FAT driver had issues when gRT->GetTime() did not return a valid date time (what TemplateRealTimeClockLib does). Harry recently was working on a BlockIo device on a new platform and got the same issue again (we did not have this patch in our Fat binary). Because, he was using EFI Shell, he took the opportunity to search on gRT->GetTime() in the code to ensure the return status was checked. ________________________________________ From: Jordan Justen [[email protected]] Sent: 09 May 2013 18:01 To: Andrew Fish; Olivier Martin Cc: [email protected] Subject: Re: [edk2] [PATCH] ShellPkg: Check the error of gRT->GetTime() On Thu, 2013-05-09 at 09:48 -0700, Andrew Fish wrote: > I don't see why we assume that the time is always correct? > What happens if you lose the battery and your driver knows the time is > not valid per the UEFI spec it would return EFI_DEVICE_ERROR? > It seems reasonable for the code calling GetTime() to deal with a > EFI_DEVICE_ERROR return. > > EFI_DEVICE_ERROR > The time could not be retrieved due to a hardware error. Good points. Although, it doesn't seem to have been much of an issue in the past... Olivier, Is FatPkg and ShellPkg the only issues you've found? If not, at this point do you have any idea how extensive this issue is? (How much code needs to be updated.) -Jordan ------------------------------------------------------------------------------ Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.
