16 Crisis Management or Custom Firmware
If the board does not boot up or in the case of custom firmware usage (for example the replacement of the
KONTRON bootloader) you can overwrite the content of the SPI
TM flash. The following parts are necessary:
S
A desktop PC with a Windows ® or Linux ® operating system
S
A special NVIDIA ® USB driver (only Windows ® )
S
One USB Type A cable and the KONTRON adaptor cable KAB-USB-2
S
Two pushbuttons or one pushbutton and one jumper or something similar
S
An actual bootloader image file
For the next step you should create a link from the KTT20/pITX client port to a desktop PC (see chapter 'USB
Client Interface'). Make sure that you have the power cable plugged-in. Then connect the pushbuttons or a
pushbutton/jumper combination to the pin header J1400 (button or jumper) and J900 (button).
J900
J1400
To set the board into recovery mode first the pushbutton J1400 (if you use two buttons) and then the
pushbutton J900 must be pressed until the LEDs go on.
