Hi, experts:
I have a question about UEFI Shell App:
1. UEFI App’s EntryPoint usually is as below:
UefiMain (
IN EFI_HANDLE ImageHandle,
IN EFI_SYSTEM_TABLE *SystemTable
)
When launches App at Shell command prompt:
EFI_LOADED_IMAGE_PROTOCOL / EFI_SHELL_PARAMETERS_PROTOCOL will be installed on
ImageHandle!
So:
How about EFI_SHELL_PROTOCOL?
Would it be also installed on ImageHandle?
I tried to :
Status = gBS->OpenProtocol(
ImageHandle,
&gEfiShellProtocolGuid,
(VOID **)&pTstEfiShellProtocol,
ImageHandle,
NULL,
EFI_OPEN_PROTOCOL_GET_PROTOCOL
);
But failed, and Status = EFI_UNSUPPORTED !
My Shell version is: (ver cmd in shell prompt)
UEFI Interactive Shell v2.1
Best wishes,
