I noticed the Neo+ 2 has a blue LED:

 

    line  10:      unnamed "nanopi:green:pwr" output active-high [used]
    line  20:      unnamed "nanopi:blue:status" output active-high [used]

 

It's not doing the heartbeat flash like the NanoPi Duo.

any news to this problem.

Still facing the same problem. I can control the RED led on my NanoPi NEO Core2 but not the blue one...

And it's done.  We have zillions of similar problems. Time is limited and not important and not urgent ones are consciously ignored.

hmm I would love to do that. but as I'm using a NanoPi NEO Core2 I don't wan't to code on the wrong image.

For me it's currently a too hard start to first figure out how to develop the write image first for the Core 2 and

then search start searching for the right LED pins etc to get it working.

If someone could build a NanoPi NEO Core2 image I could definitely start helping in improving the side of the Core 2...

The only difference is few bits in the device tree. This image should work just fine: https://dl.armbian.com/nanopineoplus2/

hmm ok 

Currently I use the "Nanopi Neo 2" image. So is the nano pi neo plus2 closer to the "NanoPi NEO Core2"?

I just thought the Neo Core 2 is the bare bone cpu board compared the the Neo 2 where USB and Ethernet Jack is present...

In case it is helpful, here's the DT addition that I use for the LEDs on both the NanoPi Neo Plus2 and the Core2 (both boards are the same in this regard):

        leds {
                compatible = "gpio-leds";

                pwr {
                        label = "nanopi:red:pwr";
                        gpios = <&r_pio 0 10 GPIO_ACTIVE_HIGH>;
                        default-state = "on";
                };

                status {
                        label = "nanopi:green:status";
                        gpios = <&pio 0 10 GPIO_ACTIVE_HIGH>;
                        linux,default-trigger = "heartbeat";
                };
        };

As a side note - for my own use, I made a custom board build configuration for the Core2 (DT); see https://github.com/5kft/build/blob/master/patch/kernel/sunxi-next/update-H5-board-config-support.patch and https://github.com/5kft/build/blob/master/patch/u-boot/u-boot-sunxi/update-nanopineocore2.patch.  I'm sure there's a better way of managing all of this (e.g., DT overlays), but unfortunately I haven't had any time to spend on this.  Perhaps you could extract what you need from this patchset if it might be useful to you.
