Create a new directory for an EDK II WORKSPACE.

The code block below shows the GIT clone operations required to pull the EDK II
source tree, the FatPkg sources, the pre-built versions of BaseTools as WIN32
binaries, and the edk2-non-osi repository that provides a binary file for the
Quark Remote Management Unit (RMU).

Next it sets environment variables that must be set before running
```edksetup.bat```. Since content is being pulled from multiple repositories,
the EDK II [Multiple Workspace](
https://github.com/tianocore/tianocore.github.io/wiki/Multiple_Workspace)
feature is used.

Next, the ```edksetup.bat``` file is run to complete the initialization of an
EDK II build environment.  Two example build commands are shown.  The first one
in ```QuarkPlatformPlg/Quark.dsc``` builds a full UEFI firmware image that is
able to boot the built-in UEFI Shell and Linux from a micro SD FLASH card.  The
second one in ```QuarkPlatformPkg/QuarkMin.dsc``` builds a minimal firmware
image that is useful for initial power-on and debug of new features.

```cmd
git clone https://github.com/tianocore/edk2.git
git clone https://github.com/tianocore/edk2-FatPkg.git FatPkg
git clone https://github.com/tianocore/edk2-BaseTools-win32.git
git clone https://github.com/tianocore/edk2-non-osi.git

## **Build Features**

The table below contains a summary of the build flags to enable or disable
features on the build command line using ```-D``` flags.

| **Define Name**            | **Default Value** | **Supported Values** |
| -------------------------- | ----------------- | -------------------- |
| ```GALILEO```              |              GEN2 | GEN1, GEN2           |
| ```LOGGING```              |              TRUE | TRUE, FALSE          |
| ```SOURCE_DEBUG_ENABLE```  |             FALSE | TRUE, FALSE          |
| ```PERFORMANCE_ENABLE```   |             FALSE | TRUE, FALSE          |
| ```SECURE_BOOT_ENABLE```   |             FALSE | TRUE, FALSE          |
| ```MEASURED_BOOT_ENABLE``` |             FALSE | TRUE, FALSE          |
| ```TPM_12_HARDWARE```      |              NONE | NONE, LPC, ATMEL_I2C, INFINEON_I2C |

* ```GALILEO``` - Used to specify the type of Intel(R) Galileo board type.  The
  default is ```GEN2``` for the [Intel(R) Galileo Gen 2 Development Board](
  http://www.intel.com/content/www/us/en/embedded/products/galileo/galileo-overview.html).
  The other supported value is ```GEN1``` for the [Intel(R) Galileo Development Board](
  http://www.intel.com/content/www/us/en/embedded/products/galileo/galileo-g1-datasheet.html).
  Add ```-D GALILEO=GEN1``` to the build command for [Intel(R) Galileo Development Board](
  http://www.intel.com/content/www/us/en/embedded/products/galileo/galileo-g1-datasheet.html).

* ```LOGGING``` - Used to enable/disable logging messages from DEBUG() macros to
  a serial UART.  The default is TRUE for enabled when the BUILDTARGET is DEBUG
  (```-b DEBUG```).  The default is FALSE for disabled when the BUILDTARGET is
  not DEBUG (e.g. ```-b RELEASE```).  Add ```-D LOGGING``` to the build command
  to force logging enabled.  Add ```-D LOGGING=FALSE``` to force logging
  disabled.

* ```SOURCE_DEBUG_ENABLE``` - Used to enable/disable source level debug using the
  [Intel(R) UEFI Development Kit Debugger Tool](
  https://firmware.intel.com/develop/intel-uefi-tools-and-utilities/intel-uefi-development-kit-debugger-tool).
  The default is FALSE for disabled.  Add ```-D SOURCE_DEBUG_ENABLE``` to the
  build command line to enable source level debug.

* ```PERFORMANCE_ENABLE``` - Used to enable/disable boot performance measurement.
  The default is FALSE for disabled.  Add ```-D PERFORMANCE_ENABLE``` to the
  build command line to enable boot performance measurement.  When this feature
  is enabled, both ```LOGGING``` and ```SOURCE_DEBUG_ENABLE``` are automatically
  disabled so there is not boot time overhead from the serial UART for logging
  messages or the debug agent.

* ```SECURE_BOOT_ENABLE``` - Used to enable/disable UEFI Secure Boot features.
  The default is FALSE for disabled.  Add ```-D SECURE_BOOT_ENABLE``` to the
  build command line to enable UEFI Secure Boot features.

* ```MEASURED_BOOT_ENABLE``` - Used to enable/disable measurement of firmware
  code and data into a TPM 1.2 hardware device.  The default is FALSE for
  disabled.  Add ```-D MEASURED_BOOT_ENABLE``` to the build command line to
  enable UEFI Secure Boot features.

* ```TPM_12_HARDWARE``` - Used to specify the type of TPM 1.2 hardware device
  that is connected to the Galileo board.  This define is valid if the measure
  boot feature is enabled using ```-D MEASURED_BOOT_ENABLE```.  The default is
  NONE for no TPM 1.2 hardware device connected.  Add ```-D TPM_12_HARDWARE=LPC```
  for a TPM hardware device attached to an LPC bus (not supported on on Intel(R)
  Quark SoC X1000).  Add ```-D TPM_12_HARDWARE=ATMEL_I2C``` for an
  [Atmel AT97SC3204T](http://www.atmel.com/devices/AT97SC3204T.aspx) or
  [Atmel AT97SC3205T](http://www.atmel.com/images/atmel-8883s-tpm-at97sc3205t-datasheet-summary.pdf)
  attached to the I2C bus of the Galileo Arduino header.  Add
  ```-D TPM_12_HARDWARE=INFINION_I2C``` for an [Infineon SLB9645](
  http://www.infineon.com/dgdl/Infineon-TPM+SLB+9645-DS-v01_00-EN.pdf?fileId=5546d4625185e0e201518b83d0c63d7c)
  attached to the I2C bus of the Galileo Arduino header.  The ATMEL_I2C setting
  has been tested with the [CryptoShield](https://www.sparkfun.com/products/13183)
  available from [SparkFun](https://www.sparkfun.com/).

## **FLASH Update using DediProg SF100**

Once the sources have been downloaded, an EDK II build environment established,
and an EDK II firmware image has been built, the EDK II firmware image needs to
installed into the FLASH device on the target Galileo development board.  One
way to do this is with the [Dediprog SF100 IC Programmer](
http://www.dediprog.com/pd/spi-flash-solution/SF100).

* Install the DediProg SF100 software.

* Connect the DediProg SF100 to the Galileo development board.

    ![](https://github.com/tianocore/tianocore.github.io/wiki/Projects/QuarkPlatformPkg/Images/Dediprog.jpg)

* Make sure ```dpcmd.exe``` is in ```PATH```

  ```PATH=%PATH%;"c:\Program Files (x86)\DediProg\SF100"```

* **NOTE**: It is recommended that the FLASH image that was shipped with the
  Galileo development board be read and saved before updating FLASH image.  The
  command shown below read the FLASH image and saves it to the file
  called ```GalileoOriginalFirmware.bin```.

  ```dpcmd.exe -r GalileoOriginalFirmware.bin```

* Update FLASH image using either the DediProg SF100 GUI or ```dpcmd.exe```.
  - Example update of Galileo firmware image when BUILDTARGET is DEBUG (default)

    ```dpcmd.exe -u%WORKSPACE%\Build\Quark\DEBUG_VS2015x86\FV\QUARK.fd ```

  - Example update of Galileo firmware image when BUILDTARGET is RELEASE
    (```-b RELEASE```)

    ```dpcmd.exe -u%WORKSPACE%\Build\Quark\RELEASE_VS2015x86\FV\QUARK.fd ```

## **Setting up a Serial Console and Booting to UEFI Shell**

After the FLASH is updated on Galileo, a serial cable is connected between the
host system and the Galileo target.  A serial terminal emulator (such as
[Tera Term](https://en.osdn.jp/projects/ttssh2/releases/)) can be used to see
the logging messages from DEBUG() macros and the serial console for the UEFI
Boot Manager, UEFI Shell, and operating system.

The default serial communication parameters for the Intel(R) Galileo Gen 2
Development Board is 921600,n,8,1 with no hardware flow control.

![](https://github.com/tianocore/tianocore.github.io/wiki/Projects/QuarkPlatformPkg/Images/TeraTermSerialParameters.png)

The default serial communication parameters for the Intel(R) Galileo Development
Board is 461800,n,8,1 with no hardware flow control.

The following changes to the [Tera Term](https://en.osdn.jp/projects/ttssh2/releases/)
configuration files are recommended for UEFI serial console compatibility.
Some of the later use cases involve using the TCPIP mode, so some of these
recommendation apply to the TCPIP use cases.

* TERATERM.INI - Set terminal size to 80 x 25 and terminal settings to UTF8.

![](https://github.com/tianocore/tianocore.github.io/wiki/Projects/QuarkPlatformPkg/Images/TeraTermTerminal.png)

* TERATERM.INI - Set font type to Terminal to support box drawing glyphs.

![](https://github.com/tianocore/tianocore.github.io/wiki/Projects/QuarkPlatformPkg/Images/TeraTermFont.png)

* TERATERM.INI - Disable line mode to make TCPIP mode work like COM port mode.

```ini
; Line at a time mode
EnableLineMode=off
```

* KEYBOARD.CNF - Disable VT function keys for F5..F10

```ini
[VT function keys]
;F6 key
;F6=64
;F7 key
;F7=65
;F8 key
;F8=66
;F9 key
;F9=67
;F10 key
;F10=68
```

* KEYBOARD.CNF - Disable X function keys for F1..F4

```ini
[X function keys]
; F1 key
XF1=off
; F2 key
;XF2=60
XF2=off
; F3 key
;XF3=61
XF3=off
; F4 key
;XF4=62
XF4=off
; F5 key
;XF5=63
```

* KEYBOARD.CNF - Add UEFI serial console sequences for F1..F10

```ini
[User keys]
User1=59,0,$1B[M
User2=60,0,$1B[N
User3=61,0,$1B[O
User4=62,0,$1B[P
User5=63,0,$1B[Q
User6=64,0,$1B[R
User7=65,0,$1B[S
User8=66,0,$1B[T
User9=67,0,$1B[U
User10=68,0,$1B[V
```

Connect power adapter to Galileo development board, and the logging messages
should be seen, followed by 5 second countdown, followed by an automatic boot to
the built-in UEFI Shell.

![](https://github.com/tianocore/tianocore.github.io/wiki/Projects/QuarkPlatformPkg/Images/UefiShell.png)

## **Source Level Debug Using Intel(R) UEFI Development Kit Debugger Tool**

### Pre-requisites

* Intel(R) UEFI Development Kit Debugger Tool User Manual for Ver 1.5 or higher:
  Available from https://firmware.intel.com/develop/intel-uefi-tools-and-utilities/intel-uefi-development-kit-debugger-tool
* Intel(R) UEFI Development Kit Debugger Tool Ver 1.5 or higher: Available from
  https://firmware.intel.com/develop/intel-uefi-tools-and-utilities/intel-uefi-development-kit-debugger-tool
* [Tera Term](https://en.osdn.jp/projects/ttssh2/releases/) or other serial
  terminal emulator with TCPIP support

Follow instructions in Intel(R) UEFI Development Kit Debugger Tool User manual
to setup host system.

Build a firmware image with SOURCE_DEBUG_ENABLE enabled
(```-D SOURCE_DEBUG_ENABLE```).  This will select the appropriate libraries,
debug agent, and PCDs for Galileo.  Galileo does not support a USB 2.0 debug
port, so only the UART based communications library is used.

Use Dediprog SF100 to update the Galileo development board FLASH image.

Update the ```[Debug Port]``` section of the SoftDebugger.ini file with the host
side UART configuration settings.  The following example uses COM5, which must
be updated with the COM port the Galileo target is attached.  The following
example also shows a baud rate of 921600 which is correct for a Galileo Gen 2.
If a Galileo Gen 1 is being used, set the baud rate to 460800.  By default, the
Galileo console is redirected to TCPIP port 20715.

```ini
[Debug Port]
Channel = Serial
Port = COM5
FlowControl = 0
BaudRate = 921600
Server =
```

Connect power adapter to Galileo development board and run a command script with
the contents below to start a Tera Term session on TCPIP port 20715 and start
the Intel(R) UEFI Development Kit Debugger Tool using UART connection between
the host and target and WinDbg.  The REBOOT button on the Galileo development
board may need to be pressed for the debugger to perform the initial connect.

```cmd
start "Console" /B "c:\Program Files (x86)\teraterm\ttermpro.exe" localhost:20715 /nossh
start "Debugger" /B "C:\Program Files (x86)\Intel\Intel(R) UEFI Development Kit Debugger Tool\eXdi.exe" /LaunchWinDbg
```

The figure below should be seen when a connection is made.  The SoftDebugger
Debug Console window shows the status of the connection between the host and the
target.  The Tera Term window shows the console output from the SEC phase until
the debug agent is initialized.  The WinDbg window shows that the debugger is
connected and the WinDbg application can be used for run control, breakpoint
management, and viewing call stacks, local variables,  global variables, etc.

![](https://github.com/tianocore/tianocore.github.io/wiki/Projects/QuarkPlatformPkg/Images/UdkDebugger.png)

## **Debug Using Intel(R) System Debugger using OpenOCD**

Setup hardware and software components following the instructions in the article at:
https://software.intel.com/en-us/articles/using-intel-system-debugger-with-openocd

Connect power adapter to Galileo development board.

The following batch file starts Tera Term serial console on COM5 at 921600 baud,
starts OpenOCD using a Flyswatter2, and starts Intel(R) System Studio Debugger.
Select the **Connect** button to complete the host to target connection.

```cmd
set OPENOCD="C:\Program Files (x86)\IntelSWTools\system_studio_for_windows_2016.0.023\debugger\openocd"
start "Console" /B "c:\Program Files (x86)\teraterm\ttermpro.exe" /C=5 /BAUD=921600
start "OpenOcd" /B %OPENOCD%\bin\openocd.exe -f ..\scripts\interface\ftdi\flyswatter2.cfg -f ..\scripts\board\quark_x10xx_board.cfg
call "C:\Program Files (x86)\IntelSWTools\System Debugger 2016\system_debugger\start_xdb_gdb_remote.bat"
```

When **Reset Target** is selected, the Galileo development board does not always
halt at the first instruction at the reset vector.  If debug is required from
the first instruction of the reset vector, then update the file
```UefiCpuPkg/SecCore/Ia32/ResetVector.asm``` and change the two NOP
instructions at the label ```ResetHandler:``` to ```JMP $```.  This puts the CPU
into a wait loop until the debugger is connected and the debugger is used to set
instruction pointer to the next instruction.

```
;
; For IA32, the reset vector must be at 0xFFFFFFF0, i.e., 4G-16 byte
; Execution starts here upon power-on/platform-reset.
;
ResetHandler:
;    nop
;    nop
    jmp $
ApStartup:
    ;
    ; Jmp Rel16 instruction
    ; Use machine code directly in case of the assembler optimization
    ; SEC entry point relative address will be fixed up by some build tool.
    ;
    ; Typically, SEC entry point is the function _ModuleEntryPoint() defined in
    ; SecEntry.asm
    ;
    DB      0e9h
    DW      -3
```

## **Install, Configure, and Boot Linux**

* Download SD Card Linux Image: Available at
  http://www.intel.com/content/www/us/en/support/boards-and-kits/intel-galileo-boards/000005614.html
* Extract the SD Card Linux Image to a FAT formatted Micro SD FLASH device
* Install Micro SD FLASH device into Galileo development board

Connect power adapter to Galileo development board and boot to the UEFI Shell.

From the UEFI Shell execute the following commands to copy the GRUB EFI boot
loader to ```\efi\boot\bootia32.efi```.  This allows the UEFI Boot Manager, on
all future boots, to auto detect that the Micro SD FLASH device is bootable.

```
Shell> connect -r
Shell> map -r
Shell> fs0:
FS0:> mkdir efi
FS0:> mkdir efi\boot
FS0:> cp grub.efi efi\boot\bootia32.efi
```

The GRUB boot loader is set to a UART baud rate of 115200.  A couple changes are
required to change the baud rate to 460800 for Galileo Gen 1 or 921600 for
Galileo Gen 2.  From the UEFI Shell, execute the following commands to make a
backup copy and edit the GRUB configuration file.

```
FS0:> cp boot\grub\grub.conf boot\grub\grub.conf.org
FS0:> edit boot\grub\grub.conf
```

* Delete the lines associated with the boot option with the following title.

```
title Clanton SVP kernel-SPI initrd-SPI IMR-On IO-APIC/HPET NoEMU
```

* Replace the two instances of 115200 in the following line to 460800 for
  Galileo Gen 1 or 921600 for Galileo Gen 2.

```
kernel /bzImage root=/dev/ram0 console=ttyS1,115200n8 earlycon=uart8250,mmio32,$EARLY_CON_ADDR_REPLACE,115200n8 reboot=efi,warm apic=debug rw LABEL=boot debugshell=5 rootimage=image-full-galileo-clanton.ext3
```
* Press F3 to save the file
* Run the ```exit``` command to exit from the UEFI Shell and return to the
  UEFI Boot Manager
* Select **Boot Manager**
* Select **UEFI Misc Device** for the Micro SD FLASH device.
* GRUB should run and Linux should boot with serial log messages.
* When the serial log messages stop, change the Tera Term baud rate to 115200
* Login as ```root```.   No password is required.
* Use ```vi``` to edit ```/etc/inittab```
* Change the baud rate of ttyS1 from 115200 to 460800 for Galileo Gen 1 or
  921600 for Galileo Gen 2.  The line that need to be updated is shown below

```
S:2345:respawn:/sbin/getty 115200 ttyS1
```

* Save the updated ```/etc/inittab```
* Run ```reboot -f``` to shutdown Linux and reboot the platform.
* Set the Tera Term baud rate back to 460800 for Galileo Gen 1 or 921600 for
  Galileo Gen 2.

After these changes both the EDK II firmware and the Linux operating system use
the same baud rate.

### **Testing ACPI S3 Sleep**

The ACPI S3 Sleep and Resume feature can be tested on a Galileo development
board using the Real Time Clock (RTC) for a wake event.  The shell script shown
below arms the RTC wake alarm 10 seconds in the future and puts the system to
sleep.  A shorter time in seconds can be passed in as the first argument to the
script, but do not use times shorter than 2 or 3 seconds.

**NOTE**: The stmmac module is unloaded because the module is not compatible
with S3 resume.

```sh
#
# Unload NIC driver that causes S3 to fail
#
rmmod stmmac

#
# Disable RTC wake alarm
#
echo 0 > /sys/class/rtc/rtc0/wakealarm

#
# Compute wake time that is $1 seconds in the future
#
let WakeTime=`date '+%s'`
echo $WakeTime
if ["$1" = ""]; then
  let WakeTime=$WakeTime+10
else
  let WakeTime=$WakeTime+$1
fi
echo $WakeTime

#
# Enable RTC wake alarm $1 seconds in the future
#
echo $WakeTime > /sys/class/rtc/rtc0/wakealarm

#
# Put systems into ACPI S3 sleep state
#
echo mem > /sys/power/state
```

## **UEFI Secure Boot Feature and Physical Presence**

Build a firmware image with SECURE_BOOT_ENABLE enabled
(```-D SECURE_BOOT_ENABLE```). This builds in support for UEFI authenticated
variables, UEFI image verification, and UEFI Secure Boot configuration screens
in the Device Manager. In order to change the UEFI Secure Boot configuration,
the user must assert physical presence.  The Galileo development board only has
two push buttons (REBOOT and RESET).  The REBOOT button unconditionally reboots
the platform. The RESET button asserts the reset signal on the Arduino header
and is also connected to a GPIO pin, so the state of the RESET button can be
read.  The user asserts physical presence by holding the RESET button while the
Galileo development board boots, or by holding the RESET button while selecting
the **Secure Boot Configuration** option in the Device Manager.

Use Dediprog SF100 to update the Galileo development board FLASH image.

Connect power adapter to Galileo development board and boot to the UEFI Boot
Manager by pressing F2 or running the ```exit``` command from the UEFI Shell.
Select **Device Manager** and then**Secure Boot Configuration**.  Change
**Customize Secure Boot** to **Customized** and then select **Custom Secure Boot
Options**.  If **Custom Secure Boot Options** can not be selected, then physical
presence was not asserted using one of two methods listed above.  Assert
physical presence and try again.

The **Custom Secure Boot Options** screen allows the Galileo development board
to be enrolled into UEFI Secure Boot.  See [How to Sign UEFI Drivers & Application V1.31](
http://sourceforge.net/projects/edk2/files/General%20Documentation/SigningUefiImages%20-v1dot31.pdf/download)
in the [SecurityPkg Wiki](https://github.com/tianocore/tianocore.github.io/wiki/SecurityPkg)
for details on how to complete the UEFI Secure Boot enrollment.

## **Enable Measured Boot Feature using Atmel I2C TPM on CryptoShield**

Build a firmware image with MEASURED_BOOT_ENABLE enabled
(```-D MEASURED_BOOT_ENABLE```) and TPM_12_HARDWARE set to ATMEL_I2C
(```-D TMP_12_HARDWARE=ATMEL_I2C```). This builds in the TCG PEIM and DXE
modules and uses the library for the Atmel I2C TPM hardware device.

Use Dediprog SF100 to update the Galileo development board FLASH image.

Attach the CryptoShield to the Arduino header of the Galileo development board
as shown below.

Connect power adapter to Galileo development board and boot to the UEFI Shell.
In the boot logging messages, messages similar to the following should be seen
as the Atmel I2C TPM hardware device is detected and used to measure the
contents of firmware volumes and firmware tables.

## **Measuring Boot Performance**

Build a firmware image with PERFORMANCE_ENABLE enabled
(```-D PERFORMANCE_ENABLE```). This builds in the UEFI Shell and the DP.EFI
(Dump Performance) into a firmware volume and also includes a simple file system
driver for firmware volumes so the DP.EFI command can be run out of the FLASH.

Use Dediprog SF100 to update the Galileo development board FLASH image.

Connect power adapter to Galileo development board and let it boot to the UEFI
Shell.  Then use the REBOOT button or the ```reset``` UEFI Shell command to
reboot the Galileo development board.  The first boot after a FLASH update does
extra work that is only performed one time.  In order to get correct performance
measurements, use the 2nd or later boots.  After the 2nd boot, run the
```dp -s``` command.  The output should look similar to the figure below.
