LED 8 always on, normal?

[MarioVogel]

Hello,

today i got my RP, the up to date ecosystem-0.92-65-35575ed is on the SD-Card.

Is it normal that LED8 is always on? LED 8 is not as bright as the other LEDs if they are on.
If no SD Card is plugged in, then LED8 and the green LEDs are on.
If the SD Card is plugged in, then LED0 is blinking, LED8, the green and the blue LEDs are on.

Is there a way to test also LED 8 and LED 9 like the other LEDs 0-7 (monitor 0x40000030 0xFF all on monitor 0x40000030 0x00 all off)

Hi,

It is normal that LED8 is on at reduced brightness.

There was a post on how to switch it off on the old forum, but that is gone now and I can't for the life of me remember how it was done exactly. It involved sending a specific command to some linux device driver, not complicated, but the details elude me.

LEDs 8 and 9 can not be accessed through the monitor utility, of that much I am certain.

The green LED is the power indicator. The blue LED is on when the fpga has been successfully programmed from the SD card image.

Lookit that, it was still there, only not easily found: old forum post regarding LED 8

Hey THX!

Very good, the led turned off! But after cycling the power the LED is on again, it isn't fixed in the new ecosystem.

For all here the Solution again:
