Here is a quick fix for at least the 5th gigabit led.
5 other FE leds are on the builtin AR8227 (switch1 on eth1). They are also connected to the AR8327 pins as they can act as 100mb link indication however.

I compile r39315 with that patch. No change in leds
what now ? more config needed?
/sys/class/leds is empty in Mikrotik RouterBOARD 2011UAS-2HnD

comment:3 Changed 4 years ago by gminet

No, nothing more needed. This has nothing to do with /sys/class/leds or gpio. These register settings configure the hardware chip to activate the directly wired leds. I had to clean the hole build tree however, patching an already built tree and rebuilding had no effect here.
Will try again against latest trunk.
