LED Description
CR4
CR4 (chip2012, GREEN): LED for debugging CPU
Turned off when CPU is not activated yet, blinking when CPU is activated.
[Detailed information]
In normal cases (All DIP-SWs are OFF)
The LED repeats being lighted -> turned off at an interval of 300 ms
When research / inspection mode is activated (DIP-SW 1 is set to ON)
The LED repeats 2-time blinking
When maintenance mode is activated (DIP-SW2 is set to ON)
The LED repeats 3-time blinking
When only the boot loader is activated
The LED repeats ON/OFF at an interval of 1 sec.
When the status does not change to normal mode, maintenance mode, or to
research / inspection mode.
When HUB CPU is activated (Linux activated), the LED will not have its status
changed.
It would take approx. 1 min. until the LED lighting operations described above
are established.
CR5
CR5 (chip2012, GREEN): The power indicator for the HUB board
