Hi,


I use SdBusOpenInterface(). it seems successful.
but the return of the SdBusInterfaceStandard structure seems wrong.
Why size and version is 0 all the ways?

THX,


SdBusOpenInterface() Status = 0
00000031 3.26347315 SdBusOpenInterface() size = 0
00000032 3.26347455 ver = 0
00000033 3.26347622 Context = 823ee990
00000034 3.26348433 SdBusOpenInterface() ---interfReference = f810e4f0
00000035 3.26348600 interfDereference = f810e522
00000036 3.26348768 InitializeInterface = f811775c
00000037 3.26348907 AcknowledgeInt = f810e776
00000038 3.26349327 SdBusOpenInterface() success



THANKS,

Don't you have to initialize the Version and Size field of
SDBUS_INTERFACE_DATA before calling SdBusOpenInterface?

Here is the usage I see in one of the drivers:

NTSTATUS status;
SDBUS_INTERFACE_DATA interfaceData;

RtlZeroMemory(&interfaceData, sizeof(SDBUS_INTERFACE_DATA));

interfaceData.Size = sizeof(SDBUS_INTERFACE_DATA);
interfaceData.Version = SDBUS_INTERFACE_VERSION;
interfaceData.TargetObject = sffdiskExtension->TargetObject;

status = SdBusOpenInterface(&interfaceData,
&sffdiskExtension->SdbusInterfaceContext);

if (!NT_SUCCESS(status)) {
return status;
}



The bug is that the bus driver doesn't seem to validate the Size and Version
field before filling information in the InterfaceData structure. I will let
the SD driver developers know.

but ,what is SDBUS_INTERFACE_DATA ? I have the structure named
SDBUS_INTERFACE_STANDARD, how about it?

Which version is for SDBUS_INTERFACE_DATA?

and my prototype call is
Status = SdBusOpenInterface(
pDevice,//Adapter->PhyDeviceObject,//Adapter->hDevice,//UnderlyingPDO
&Adapter->SdBusIfStd,
sizeof(SDBUS_INTERFACE_STANDARD),
SDBUS_INTERFACE_VERSION);

there is four parameters, not 2.

Thanks,

Hi,
How about sffdiskExtension->TargetObject,
How can I get it?

and How about CMD53 SdIoArgument setup?
Which SD_RW_EXTENDED_ARGUMENT sdIoArgument;
//SD_RW_DIRECT_ARGUMENT sdIoArgument;
I should use?
DDK seems the second one , and I use it and SdBusSubmitRequest() successfully returned.
but the HW seems not coorect, because I can not get a register that we design to specify the FW is ready.

Why?



THanks,

what can I do ?
