Philips INCA 320 Hardware Manual page 15

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 'RapIB320Lcm.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.
