Introduction
1. Introduction
The G120 Module is a powerful, yet low-cost, surface-mount System on Module (SoM)
running the .NET Micro Framework software, which ena les the SoM to e programmed from
Microsoft's Visual Studio, y simply using a USB ca le. Programming in a modern managed
language, such as C# and Visual Basic, allows developers to accomplish much more work in
less time y taking advantage of the extensive uilt-in li raries for networking, file systems,
graphical interfaces and many peripherals.
A simple two layer circuit, with just power and some connectors, can utilize the G120 Module
to ring the latest technologies to any products. There are no additional licensing or fees and
all the development tools and SDKs are provided freely.
1.1. The .NET Micro Framework
Inspired y its full .NET Framework, Microsoft developed a lightweight version called .NET
Micro Framework (NETMF).
NETMF focuses on the specific requirements of resource-constrained em edded systems.
Development, de ugging and deployment is conveniently performed using Microsoft's
powerful Visual Studio tools, all through standard USB ca le.
Programming is done in C# or Visual Basic. This includes li raries to cover sockets for
networking, modern memory management with gar age collector and multitasking services.
In addition to supporting standard .NET features, NETMF has em edded extensions
supporting:
●General Purpose IO (GPIO with interrupt handling
●Analog input/output
●Standard uses such I2C, SPI, USB, Serial (UART)
●PWM
●Networking
●File System
●Display graphics, supporting images, fonts and controls.

Introduction
1.2. GHI Electronics and NETMF
For years, GHI Electronics has een the lead Microsoft partner on .NET Micro Framework
(NETMF). The core NETMF was also extended with new exclusive li raries for an additional
functionality, such as data ase, USB Host and WiFi.
One of the important extensions y GHI Electronics is Runtime Loada le Procedures (RLP),
allowing native code (Assem ly/C) to e compiled and loaded right from withing managed
code (C#/Visual Basic) to handle time critical and processor intensive tasks. IT can also e
used to add new native extensions to the system.
As for networking, WiFi and PPP li raries are added y GHI Electronics to the NETMF core.
Com ined with Ethernet and the other managed services, it is a complete tool ox for the
internet of things.
All the mentioned features are loaded and tested on the G120 Module. GHI Electronics
continuously maintains, upgrades and solves any of the issues on the G120 Module firmware,
to provide regular and free releases. Users can simply load the new software on the G120
Module using USB or Serial, and even use the in-field-update feature. This feature allows the
upgrade to e done through any of the availa le interface, including file system and
networking.

G120 on oot up
4. G120 On oot Up
Software run on the G120 Module is divided into different components:
●The GHI Boot loader: Initializes memories and executes TinyBooter. It is also used to
update TinyBooter.
●TinyBooter does set-up for, and then, loads the firmware (TinyCLR, NETMF core, and
GHI extensions). It is also used to update the NETMF firmware and its system
configurations.
●TinyCLR and NETMF (The firmware): interprets and executes the managed
application. It is used for other functions such as loading and/or de ugging the
managed application.
●The managed application (C# - Visual Basic); developed y customers.
●Optional: Native RLP routines (C and/or assem ly, descri ed in the Runtime Loada le
Procedure section).
If the oot mode pins, LDR0 and LDR1, are left floating (internal pull up), or pulled high
externally, the default oot-up sequence executes as the following:
●The GHI oot loader initializes Flash and RAM memory and looks for a valid
TinyBooter and passes execution to it.
●TinyBooter prepares the G120 hardware resources required y the NETMF Core
environment and passes execution to NETMF TinyCLR.
●If a valid end-user em edded application exists, it gets executed.
4.1. Boot Mode Pins
Default start-up execution can e changed using two control pins, they are active low and
have internal weak pull up resistors:
Pin 8, LDR0 Pin 14, LDR1 Effect
(Ignored) High Default, execute all levels
High Low Execute the Boot Loader and TinyBooter ut
do not execute NETMF TinyCLR
Low Low Execute Boot Loader ut do not execute
TinyBooter

4.2. GHI Boot Loader vs. TinyBooter vs. G120 Firmware
(NETMF/Tiny LR)
The ta le elow gives greater detail of the characteristics of each level of execution.
GHI Boot Loader TinyBooter NETMF TinyCLR (firmware)
Used to update G120
TinyBooter or for low level
G120 flash maintenance.
Used to update the G120
firmware (NETMF TinyCLR)
and to update system
configurations such as
networking settings.
Used to deploy, execute and
de ug the managed NETMF
application code. In other
words, it plays the role of a
virtual machine.
Emergency use or when GHI
releases a new TinyBooter. Sometimes used. Always used.
Pre- urned into the G120
Module's flash memory. Can't
e updated.
Replacea le using the GHI
Boot Loader
Replacea le; under control of
TinyBooter
Controlled through simple text
commands and X-modem.
Any terminal, such as
teraterm or hyper terminal,
can e used.
Controlled through MFDeploy
or FEZ Config tools.
Runs the user application and
accepts commands from
Visual Studio for de ugging
purposes.
When applying updates, the lowest level software should e updated first. For example, if
oth the firmware (TinyCLR) and TinyBooter need updates, TinyBooter should e updated
first.
4.3. The Loader and Firmware Debug Access Interface
The communication etween a PC and the G120 Module can e done using a USB port or a
serial port (COM). This interface can e used for updating, deploying or de ugging the
software components.
The MODE Pin is used to select USB vs serial. When the pin is high or left floating (internal
weak pull up resistor) the system will run in USB mode. When the pin is low, serial mode is
used over COM1 on the G120 Module.
When USB is selected, the drivers needed on the PC are included in the GHI SDK. Two
different drivers are availa le. The first one is a virtual COM driver used y the GHI loader.
The second one is used y TinyBooter and NETMF TinyCLR.

The GHI Boot Loader
5. The GHI oot Loader
The G120 Boot Loader software is pre-loaded and locked on the G120 Module. It is used to
update TinyBooter and can e used to do a complete erase all flash memory. The GHI oot
loader is rarely needed ut it is recommended to keep access availa le in all project designs.
The GHI oot loader accepts simple commands sent with the help of a terminal service
software, such as TeraTerm or Hyper Terminal. A command character is sent and the oot
loader performs an action; results are returned in a human friendly format followed y a "BL"
indicating that the oot loader is ready for the next command. All commands and responses
use ASCII encoded characters.
The G120 on oot up section provides the required information on how to choose the access
interface and how to access the GHI oot loader.

Notes:
●Commands are not followed y pressing the “ENTER” key. The single command letter is sent to the
G120 Module; which immediately egins executing the command.
●The Boot loader commands are case sensitive.
5.2. Updating TinyBooter
GHI Electronics' SDK includes FEZ Config, a Windows program that can e used to update
all software components of the G120 Module; as well as, system settings (configuration
parameters). Although FEZ Config is recommended as the tool to use, the same process
can e performed manually using an ASCII terminal program. The next section shows how
use GHI's FEZ Config. The manual procedure is descri ed in Updating TinyBooter
Manually

Updating TinyBooter using FEZ onfig.
The following procedures' images are from version 2.0.2.0 of FEZ Config running on
Windows 8.01. The images may vary with other versions.
The first step is to interface the G120 with the PC. This is est done using the USB pins,
and the appropriate ca le. Once Windows loads the appropriate driver:
Launch FEZ Config. Under “Device” make sure “USB” is selected and G120 is the device.
Now follow the menu: Advanced>Loader (TinyBooter) Update>G120 Module

Leave all defaults and click on “Next” Answer any dialog questions. The program will flash
the module and display it's progress.
Updating TinyBooter Manually
As stated earlier, FEZ Config is the recommended tool for updating TinyBooter on the module.
This section descri es a manual process. The only advantage of performing flashing this way
is that it allows updates from any device with a serial connection; independent of operating
system.
Depending on the state of the MODE Pin (see the The Loader and Firmware De ug Access
Interface section), the GHI oot loader will use the USB or the serial interface. When using
USB, it requires a virtual serial interface driver on the USB Host. For Windows, this means the
GHI oot loader on the G120 Module will appear as a serial device in either case. It should e
noted that the serial pins on G120 are TTL level; so, an RS232 level converter is needed to
wire the serial pins to a PC's serial port.
Serial communications parameters are: 152000 aud, 8- it data with one stop it and no
parity.
Rev. 0.10 Page 17 of 67 www.GHIElectronics.com

GHI Electronics,LLC G120 SoM User Manual
The GHI Boot Loader
Loading using XMODEM
The GHI oot loader uses the XMODEM protocol to receive the TinyBooter file.
In this example, a serial program running on a PC is used to show the transfer.
Once the appropriate serial port on the PC is opened, a user can start sending commands,
such as entering V to see the oot loader version num er.
Loading new firmware is simple; ut it requires a terminal that supports XMODEM file transfer.
XMODEM has many versions, GHI oot loader requires:
●1K transfers,
●16Bit CRC error checking.
Instructions for updating TinyBooter (commands are case sensitive):
1. Boot the G120 using the Pin configuration descri ed in the Boot Mode Pins section to
start the Boot loader's command/control interface. Access the oot loader using
TeraTerm (or other terminal program).
2. To confirm the GHI oot loader is active and responding enter V to see the version
num er. The data sent to the GHI boot loader is not echoed to the sender. This means
that no V will appear on the terminal; the oot loader will transmit the version num er,
followed y “BL” (which is an indication it is ready to receive another command.
3. Erase the flash memory using E command then press Y to confirm (this will take
several seconds).
4. Initiate transfer y typing X; this tells the Boot loader to wait for the transmission of
data from the terminal program. After the X command is entered, the GHI Boot loader
will start sending ack the “C” character continuously. This “C” is an indicator that tells
XMODEM a device is waiting for data. Once the “C” character appears on the terminal
window, select XMODEM transfer and point the software to the firmware file
"Loader.ghi” as shown elow:
If using TeraTerm: In the menu, select File > Transfer > XMODEM > Send...

Next, select the file containing TinyBooter, “Loader.ghi” from the C:\Program Files(x86)\GHI
Electronics folder; make sure to use the “Loader.ghi” file specified under a G120 su folder,
and make sure to select the 1K option in TeraTerm.
Updating the firmware may take a few seconds. Once loading has finished, Exit the terminal
program and reset the G120 Module.

5.3. TinyBooter
TinyBooter has two functions;
1. y default it executes the NETMF TinyCLR firmware,
2. the other function of TinyBooter is to load new firmware (TinyCLR). Whenever GHI
Electronics releases new firmwareTinyBooter is used to load it.
The G120 on oot up chapter provides the pin configuration required to choose an access
interface and how to invoke TinyBooter.
When preparing to install new firmware, it is important to make sure that the version of
TinyBooter supports the new TinyCLR. This is done using the “Check for device update” in
FEZ Config. Version num ers of oth TinyBooter and TinyCLR are always listed in the current
GHI Electronics' SDK Release Notes. Release Notes are installed with the SDK; they may
also e viewed online y following the GHI SDK Li rary links to the SDK.
If TinyBooter needs to e updated , do it efore updating TinyCLR. See Updating TinyBooter
using FEZ Config.
NOTE: TinyCLR can also e updated using In-Field Update.
