I'm new to this and using CommandInit because I've seen it used after
ShellInitialize in other files. I removed it and now it doesn't hang, but
ShellExecute returns Invalid Parameter.
My goal is to execute a uefi application from inside another uefi
application. Here is my code:
////////////////////////////////////////////////
// Test.c
////////////////////////////////////////////////
#include <Library/UefiLib.h>
#include <Library/UefiApplicationEntryPoint.h>
#include <Library/ShellLib.h>
EFI_STATUS
EFIAPI
UefiMain (
IN EFI_HANDLE ImageHandle,
IN EFI_SYSTEM_TABLE *SystemTable
)
{
EFI_STATUS Status;
Print (L"ImageHandle: %x\n", ImageHandle);
Status = ShellInitialize ();
Print (L"ShellInitialize: %r\n", Status);
Status = ShellExecute (
ImageHandle,
L"fs1:\\Load.efi",
FALSE,
NULL,
NULL
);
Print (L"ShellExecute: %r\n", Status);
return EFI_SUCCESS;
}
////////////////////////////////////////////////
// Load.c
////////////////////////////////////////////////
#include <Library/UefiLib.h>
#include <Library/UefiApplicationEntryPoint.h>
EFI_STATUS
EFIAPI
UefiMain (
IN EFI_HANDLE ImageHandle,
IN EFI_SYSTEM_TABLE *SystemTable
)
{
Print (L"Inside Load.efi.\n");
return EFI_SUCCESS;
}
fs1 contains both Load.efi and Test.efi. The output from Test.efi is:
ImageHandle: B86D1518
ShellInitialize: Success
ShellExecute: Invalid Parameter
