Documentation of Blackbird LEDs on the board
« on: January 28, 2020, 03:15:44 pm »
I can see four spots on the Blackbird board having LEDs in different colors and blinking/non-blinking.

What do the diverse LEDs on the board signal?

I have looked at the schematics (delivered on the recovery CD) and also read the labels printed on the PCB but I cannot find answers.

My current interpretation is:

  • Top right corner: Standby PSU Act: The orange power status LED on the mainboard will turn green if the system is powering on.
  • Top left corner: Status LEDs BMC (green, blue, orange) labled: Net1, Net2, HDD, UID, Power, Net3 - blue lights mean booting of OpenBMC
  • Bottom left corner: D7000 near AST 2500 (always blinking in green) - LED green PM BMC Reset (PM_BMC_HBLED_R_L)
  • Bottom center: D10103 Reset - always on, green light

I do agree with your observation. It took me 2 days to understand what's going on with the boot sequence.

I hope the C1P9S01 User Guide PDF file cover a bit more details.
