IMX233-OLinuXino-MAXI user's manual
When you power the board by battery you have to press the PWR_BUT to start the board.
If you start Linux and it is already running no matter which powering method you use
(PWR_JACK or BAT) pressing the PWR_BUT will put the Linux in power-save mode.

For the European customers we sell a power supply adapter 12V/0.5A – SY0612E.
2.5 Prebuilt software
Note that the boards arrive without Linux or SD card. The Linux image can be purchased
separately on a SD card or you can built and adjust 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(21:20) – 10-PWM3
For burning the fuse position we use the BitBurner software. This operation is discussed in details
before. Proceed with great caution when burning fuses since it is irreversible operation.
The first batches of the board and the SD-card used the Debian Linux image. After that we switched
over to ArchLinux for the ease of the package manager. Instructions how to build the ArchLinux
can be found at the gitHub address of OLinuXino.
2.6 Using BitBurner
IMPORTANT! MODIFYING THE FUSES IS IRREVERSIBLE PROCESS! BURNING THE
WRONG FUSES MIGHT DAMAGE OLINUXINO IRREVERSIBLY! BURNING WRONG
FUSES MIGHT CAUSE BOOT PROBLEMS!
BURN FUSES AT OWN RISK!
The bit burning is done via the USB of the computer connected to the OLINUXINO board and the
BitBurner software. To be able to burn the fuses you will need to make a custom cable that connects
a USB with the 3 pin holes found at the bottom of the board named “GND”, “DP”, “DM” (check
the picture below for a better view how the three wires must be connected.
