The led is software controllable, and the custom kernel you are using probably isn't configuring it correctly.bvoid wrote:On my B+, the powerled turns off a few seconds after booting and never shows up again, but the rainbow square is not displayed! I do see the Raspberry symbol on my monitor
I soldered wires straight to the board, starting from a molex-connector that's connected to a 850W psu (Antec High Current gamer).
With crappy usb-cables or power supplies, I dó see the rainbow square, so it's definitely possible that it shows.
I'm running OpenWrt Chaos Calmer RC3, with the latest ROOter scripts and a wifi usb stick and a 3g stick. Plugging out these devices does not help.
Try a raspbian image which I suspect will work.
At a guess I'd say CONFIG_LEDS_TRIGGER_INPUT=y is missing.
