1.搭建UEFI开发环境
【ubuntu 21.10】EDK2 开发环境搭建记录 - EDK II UEFI - Renegade Project (renegade-project.cn)
# 2. 编写源代码Sophon.c
#include <Uefi.h>
#include <Library/UefiLib.h>
#include <Library/BaseLib.h>
#include <Library/DebugLib.h>
#include <Library/BaseMemoryLib.h>
#include <Library/UefiBootServicesTableLib.h>
//First Program
EFI_STATUS
EFIAPI
HelloWorldEntry(
IN EFI_HANDLE ImageHandle,
IN EFI_SYSTEM_TABLE *SystemTable
)
{
EFI_STATUS Status = EFI_SUCCESS;
Print (L"Sophon\n");
return Status;
//EFI_SUCCESS
}
Sophon.inf
[Defines]
INF_VERSION = 0x00010007
BASE_NAME = Sophon
FILE_GUID = 69A6DE6D-FA9F-485E-9A4E-EA70FDCFD82F
MODULE_TYPE = UEFI_APPLICATION
VERSION_STRING = 1.0
ENTRY_POINT = HelloWorldEntry
[Sources]
Sophon.c
[Packages]
MdePkg/MdePkg.dec
ShellPkg/ShellPkg.dec
MdeModulePkg/MdeModulePkg.dec
[LibraryClasses]
BaseLib
BaseMemoryLib
DebugLib
PrintLib
UefiBootServicesTableLib

UefiLib
以上文件保存在EDK2/EmulatorPkg/Learn/Sophon下
EDK2/EmulatorPkg/EmulatorPkg.dsc
[Components]块下
加上
EmulatorPkg/Learn/Sophon/Sophon.inf
3.编译
source edksetup.sh
build -p ./EmulatorPkg/EmulatorPkg.dsc -a X64 -b DEBUG -t GCC5 -D BUILD_64 -D UNIX_SEC_BUILD -n 4
4.结果
运行
cd Build/EmulatorX64/DEBUG_GCC5/X64
./Host
