1.2. Quick Setup of the PORTER(REV.B) Board
1.2.1. Installing the USB Driver
The PORTER(REV.B) board uses Silicon Labs’ USB-to-UART Bridge controller, CP2102. Firstly, install a USB
driver for the CP2102 (a virtual COM port driver). Download the driver from the website below.
[VCP Driver kit]
http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx
1.2.2. Connecting the PC and PORTER(REV.B) Board
For connection between the PC and PORTER(REV.B) board, use a USB cable (type A to mini AB). Connect the type
A end to the PC and the mini AB end to CN18 (Debug Serial 0 / SCIF0) on the PORTER(REV.B) board. For the
location of CN18, refer to Figure 1.1.1 Location of Connectors on the PORTER(REV.B) Board.
1.2.3. Settings for Terminal Emulation Software on the PC Side
Set up the serial communications protocol for the terminal emulation software on the PC side as follows.
Communications rate 38.4 kbps (38,400 bps)
Data length 8 bits
Parity bits None
Stop bits 1 bit
Flow control None
1.2.4. Confirming Activation of the ‘u-boot’ on the PORTER(REV.B) Board
Connect the 12-V DC plug of the AC adapter supplied with the PORTER(REV.B) board to CN25 and then plug the
other end of the adapter into the outlet. Subsequently, switch Power/ACC switch (SW26) to the on side.
The PORTER(REV.B) board is activated and the following message is displayed on the screen of the terminal
emulation software.
The above screen shows the board booting from the default NOR flash interface. The error message “Card did not
respond to voltage select!” indicates the board tried to boot from the micro-sd card but a micro-sd card was not
inserted.

Alternatively, the board can be booted through the QSPI interface by shorting the JP8 jumper as described in Section
2.1.8. When booting with the QSPI flash, the screen should look similar to the one below.

1.2.5. Precautions
When the AC adapter is connected to the outlet, the 12-V DC power is supplied to the PORTER(REV.B) board and
some of the circuitry start operating. Setting the ACC switch (SW26) to the on side after that leads to the generation
of various power supply levels (including 5.0-V DC and 3.3-V DC) from the 12-V DC power.
Notes on Usage
-Performing the following operations while the AC adapter is plugged into the outlet might fatally damage
the PORTER(REV.B) board.
(1) Mounting or dismounting an optional board
(2) Plugging in or unplugging a cable
(3) Modifying switch settings
Unplug the AC adapter from the outlet when performing the above operations.
-For the PORTER(REV.B) board, be sure to use the power supply that comes with it. Applying a voltage
greater than 12 V may damage devices on the PORTER(REV.B) board.
-There are sequences for turning on and off the power supply to the R-CarM2. For the PORTER(REV.B)
board, be sure to obey the notes below.
(1) When power is turned on
Before plugging the AC adapter into the power source, be sure to confirm that the ACC switch (SW26)
is off.
It is prohibited to plug the AC adapter into a power source while the ACC switch (SW26) is on.
(2) When power is shut off
Before unplugging the AC adapter from the power source, be sure to turn off the ACC switch
(SW26).
It is prohibited to unplug the AC adapter from the power source while the ACC switch (SW26) is on.
-The typical default value for overcurrent detection by the power IC (IR3838MPBF) is defined as 7 A in
the specifications. The maximum current drawn by the VSYS and D5.0V pins on the PORTER(REV.B)
board is thus 7 A each. Therefore, operation should be such that the current drawn by either pin does not
exceed 7 A. Also ensure that the current drawn does not exceed 7 A if an IO expansion board or external
storage device is connected to the PORTER(REV.B) board.
1.2.6. Notes on Pin Function Control
For connection with the mini-monitor which comes with the PORTER(REV.B) board, the following signals are set as
GPIO outputs.
- GP7_7/MLB_CK/HSCK1
- GP7_8/MLB_SIG/HCTS1#
- GP7_9/MLB_DAT/HRTS1#
In evaluation of the MLB, HSCIF1, and so on (evaluation which entails data output from the peripheral devices) with
the PORTER(REV.B) board, be sure to change the settings for pin function control beforehand in order to avoid
collision of the R-CarM2 and output signals.

2. Switch Settings
This section describes the settings of slide switches mounted on the PORTER(REV.B) board.
2.1. Initial Settings of Jumper Switches
The following describes the initial setting and function of each slide switch on the PORTER(REV.B) board. These
settings are valid only when the PORTER(REV.B) board is switched on along with the launching of the
mini-monitor supplied with the PORTER(REV.B) board. To launch any other program than the mini-monitor,
reconfigure the slide switches according to the pin function (PFC) and GPIO functions related to that
program.
