POWERING UP
When the Inca is powered up, the Inca will boot. One of the
first things it will do is to start a self-test to make sure that it
is functional. After correct completion of the test a check is
added for the presence of a host that waits to download an
application. If a host is connected the camera waits for the
download of the application to be executed. The download
is done via the IEEE1394 interface connection. When a
download is in progress the Inca waits until the download
is completed. After completion it starts the execution of the
program.
If the test for the host is negative then the Inca will load the
program, if available, stored on the flash file system to the
SDRAM and starts the execution. If no application is
available the Inca starts capturing images and send the
images to the VGA output. The latter will be the case if an
Inca is powered-up for the very first time.

System LED
The system LED is situated next to the IEEE1394
connector. The system LED can illuminate in 3 colours
namely red, green and orange. By connecting the power to
the Inca the LED illuminates red. During start-up the LED
is illuminating orange.
Once start-up has finished the next step is the hardware
initialization. During the start of this initializing phase the
LED will blink for a very short time green and stays
constant green when this phase is terminated successfully.
If during this phase something goes wrong the led will blink
in red constantly.
During the time that a host can download an application
the general purpose LEDs 1 and 2 blink orange alternately.
After 3 seconds or a successful application download the
Inca will (try to) start the default or downloaded
application. If the system LED is blinking during this phase
probably the file 'RapIB311Lcm.rbf' or the appropriate
license file (Rhapsody.key or Clicks.key) don't reside on
the flash file system.
For a more detailed meaning of the system led colors
during the boot sequence please refer to the software
manual.
