Figure 17. LED Indicators on the Front Panel of MPC837xE-RDS
2.4.1 Power-on LED
Green Power LED (D15): indicates the system is power-on if lit.
2.4.2 RDS Programmable LEDs
Green WiFi LED (D14): indicates whether the WiFi Card is inserted and activated (SW not implemented
yet). GPIO1[10] controls this LED. Writing 0 turns on the LED, and writing 1 turns off the LED.
Red DIAG LED (D11): indicates the status of diagnostics for MPC837xE-RDS board. The LED is flashing
when system is going through the diagnostics. It is on if the system finds some problems during the
diagnostics. And it is off if the system passes the diagnostics (SW not implemented yet). GPIO1[9]
controls this LED. Writing 0 turns on the LED, and writing 1 turns off the LED.
