Neo+ 2 blue LED not flashing


Recommended Posts

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.


uname -a

Linux nanopineoplus2 4.14.15-sunxi64 #95 SMP Wed Jan 24 10:55:45 CET 2018 aarch64 GNU/Linux

any news to this problem.



Make and send a patch:


And it's done. :P 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...

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.
