SETTING UP THE OLINUXINO BOARD
2. Introduction to the chapter
This section helps you set up the OLinuXino development board for the first time.
Please consider first the electrostatic warning to avoid damaging the board, then discover the
hardware and software required to operate the board.
The procedure to power up the board is given, and a description of the default board behavior is
detailed.
2.1 Electrostatic warning
OLinuXino is shipped in a protective anti-static package. The board must not be exposed to high
electrostatic potentials. A grounding strap or similar protective device should be worn when
handling the board. Avoid touching the component pins or any other metallic element.
2.3 Requirements
In order to set up the OLinuXino optimally, the following items are required:
- 6V to 16V source of power with 1A maximum amperage.
- SWD interface programmer
- USB keyboard
- Monitor with composite interface or Personal Computer + USB-SERIAL-CABLE
- SD card with Linux image
Note that the board arrives without SD card or Linux image. You can purchase a card with Linux
separately. It is recommended that the user has basic Linux experience.
Some of the suggested items can be purchased by Olimex, for instance:
iMX233-OLinuXino-SD - SD card with the Linux image
USB-SERIAL-CABLE - USB serial console cable
SY0612E - power supply adapter 1 V/0.5A for iMX 33-OLinuXino-Maxi
Page 8 of 44

OLIMEX© 01 OLinuXino User's Manual
2.4 Powering the board
The board is powered either via the PWR jack or via a battery. It should be supplied from a 6V to
16V source with maximum current of 1A from the power jack.
If measuring the current consumption it should be around 0.06A before initializing all the
peripherals. The consumption raises to 0.1 A without LAN and USB hosts initialized and Linux
running. The consumption goes up 0.15A with the Linux running when LAN and both USB hosts
initialized.
If you have a standard USB flash drive attached to a USB host, Linux and LAN running the typical
consumption is around 0. 0A.
When powered by the typical 3.7V battery the LAN and USB-hosts are disabled. The consumption
when Linux is running is around 0.75A.
When you ower the board by battery you have to ress the PWR_BUT to start the board.
If you start Linux and it is already running no matter which owering method you use
(PWR_JACK or BAT) ressing the PWR_BUT will lead the Linux to ower save mode.
For the European customers we sell a power supply adapter 1 V/0.5A - SY0612E.
2.5 Prebuilt software
Note that the boards arrive without Linux or SD card. The Linux image can be urchased
se arately on a SD card or you can built and write it yourself.
When we program the boards we change the default position of the following HW_OCOTP_ROM0
fuses of the processor:
SD_MBR_BOOT(3) - Blown
SD_POWER_GATE_GPIO( 1: 0) – 10-PWM3
For burning the fuse position we use the BitBurner software.
The Linux image is created and downloaded from https://github.com/Freescale/fsl-community-bsp-
platform. There is explanation how to make the image from the latest sources on the github. Further

ONTROL IR UITY AND HARDWARE MODULES
5. Introduction to the chapter
Here you can find information about reset circuit and quartz crystals locations, the power supply
circuit is discussed.
5.1 Reset
OLinuXino's reset circuit includes R9 (47KΩ), R10 (47 Ω), T1, T , Q1 and a RESET button. The
RESET is specific for the fact that it is accomplished when the quarz is disconnected using 3.3V
and the transistors T1 and T .
5.2 locks
4 MHz quartz crystal Q1 is connected to pins 1 1 and 1 of the iMX 33 processor.
5 MHz quartz crystal Q is found at pins 60 and 61 of the Ethernet controller – LAN951 -JZX.

OLIMEX© 01 OLinuXino User's Manual
5.3 Power supply circuit
The power supply circuit of OLinuXino-MAXI allows flexible input supply from 6V to 16V direct
current. This means a wide range of power supplies, adapters, converters are applicable. The
maximum amperage recommended is 1A by default (0. 50mA if 3.3VIO_E is closed – read below).
If measuring the current consumption it should be around 0.06A before initializing all the
peripherals. The consumption raises to 0.1 A without LAN and USB hosts initialized and Linux
running. The consumption goes up 0.15A with the Linux running when LAN and both USB hosts
initialized.
If you have a standard USB flash drive attached to a USB host, Linux and LAN running the typical
consumption is around 0. 0A.
When powered by the typical 3.7V battery the LAN and USB-hosts are disabled. The consumption
when Linux is running is around 0.75A.
The board can be powered either from the power jack or from the LIPO_BAT connector. Note that
since standard batteries can't provide the voltage needed for the board it is advisable to use the
power from the power jack. When you use the LIPO_BAT connector and a battery the chip
handling the Ethernet and the USB hosts is disabled. Also the power button has alternative function
when the board is powered by a battery – check 6.13.
If you have successfully powered the board the RED PWR LED will turn on. Note that it is possible
to have the PWR LED on even if there isn't enough power for the board altogether with all the
peripherals currently connected.
Page 17 of 44

OLIMEX© 01 OLinuXino User's Manual
The jumper 5V_E (5V Enable) which is closed by default enables powering the board via the power
supply circuit. The 3.3V_E (3.3V Enable) jumper when closed enables the 3.3V power line.
Note the 3.3VIO_E jumper which by default is closed – it disables the U6 DC-DC converter and
enables a built-in the iMX 33 DC-DC. The problem is that the built-in DC-DC has a limit of
50mA of amperage the chip heats a bit so we decided to put external DC-DC for better stability.
When working with 3.3VIO_E closed pay attention to the amperage used.

ONNE TORS AND PINOUT
6. Introduction to the chapter
In this chapter are presented the connectors that can be found on the board all together with their
pinout and notes about them. Jumpers functions are described. Notes and info on specific
peripherals are presented. Notes regarding the interfaces are given.
6.1 Debugging interfaces
If you don't have a separate monitor or display around, and you don't wish to swap cables constantly
with your personal computer using the debug interfaces provide better option for you OLinuXino
experience.
There are three debugging options available on the OLinuXino. It is prefarable to use one of the
first two - UART or SJTAG but in case you want to use the classic 6-wire parallel JTAG there is an
option explained below.
Page 19 of 44

OLIMEX© 01 OLinuXino User's Manual
6.1.1 UART debug
The first one is a debug UART interface – U_DEBUG. You will need a cable adapter and a level
shifter to be able to debug via USB (creating virtual COM port) on your personal computer. For
instance, you can use our product MOD-USB-RS 3 as a level shifter and a simple wire connection
between the OLinuXino and MOD-USB-RS 3 's UEXT connector for a setup allowing you to
communicate with the device via a terminal program. Alternatively you can use serial to USB cable
for instance our product: USB-SERIAL-CABLE for debugging via the UART.
U_DEBUG
Pin # Signal Name Processor Pin #
1PWM0/DUART_RXD 12
2PWM1/DUART_TXD 126
3GND 30, 3 , 98, 10 , 112, 118
4DEBUG 84
You can also check the pin names at the bottom of the board under the U_DEBUG header.
6.1.2 SJTAG debug
The second interface is the Serial JTAG (SJTAG) one-wire interface. It works with various external
JTAG debugger dongles through a Freescale-defined FPGA/CPLD. SJTAG supports the Green
Hills Slingshot and ETM probe debugger dongles, as well as those made by ARM, Abatron, and
Lauterbach.
Note that the SJTAG interface comes without plastic header mounted.
The HW_DIGCTL_CTRL_USE_SERIAL_JTAG bit in the digital control block selects whether the
one-wire serial JTAG interface or the alternative six-wire parallel JTAG interface is used. There are
other options in the digital control block which might interest you and our advice is to check the
iMX 33's datasheet released by Freescale.
