sgjava Posted January 25, 2018 Posted January 25, 2018 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
Andy Posted June 6, 2018 Posted June 6, 2018 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... Andy

Andy Posted June 6, 2018 Posted June 6, 2018 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... Andy

Expand The only difference is few bits in the device tree. This image should work just fine: https://dl.armbian.com/nanopineoplus2/
Andy Posted June 6, 2018 Posted June 6, 2018 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...
5kft Posted June 6, 2018 Posted June 6, 2018 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.
