Hello all I want to control some GPIO pins on my NanoPi Neo (H3) board and installed WiringNP. Executing commands results in the error piBoardRev: Unable to determine board revision from /proc/cpuinfo I've traced the source of the error down to this line, where WiringNP tries to open /sys/class/sunxi_info/sys_info to determine which board it is running on. This path is not present in my Armbian os. I'm using 4.11.12-sun8i #20 SMP armv7l armv7l armv7l GNU/Linux Am I missing something here? Or are there alternatives to using WiringNP?

WiringNP does not work on NanopiDuo2, both in 18.04 and Ubuntu 20.04 Error piBoardRev: Unable to determine board revision from /proc/cpuinfo -> Is not NanoPi based board. -> You may want to check: -> http://www.lemaker.org/ open /sys/class/su Armbian /proc/cpuinfo content: processor : 0 model name : ARMv7 Processor rev 5 (v7l) BogoMIPS : 136.80 Features : half thumb fastmult vfp edsp neon vfpv3 tls vfpv4 idiva idivt vfpd32 lpae evtstrm CPU implementer : 0x41 CPU architecture: 7 CPU variant : 0x0 CPU part : 0xc07 CPU revision : 5 processor : 1 model name : ARMv7 Processor rev 5 (v7l) BogoMIPS : 136.80 Features : half thumb fastmult vfp edsp neon vfpv3 tls vfpv4 idiva idivt vfpd32 lpae evtstrm CPU implementer : 0x41 CPU architecture: 7 CPU variant : 0x0 CPU part : 0xc07 CPU revision : 5 processor : 2 model name : ARMv7 Processor rev 5 (v7l) BogoMIPS : 136.80 Features : half thumb fastmult vfp edsp neon vfpv3 tls vfpv4 idiva idivt vfpd32 lpae evtstrm CPU implementer : 0x41 CPU architecture: 7 CPU variant : 0x0 CPU part : 0xc07 CPU revision : 5 processor : 3 model name : ARMv7 Processor rev 5 (v7l) BogoMIPS : 136.80 Features : half thumb fastmult vfp edsp neon vfpv3 tls vfpv4 idiva idivt vfpd32 lpae evtstrm CPU implementer : 0x41 CPU architecture: 7 CPU variant : 0x0 CPU part : 0xc07 CPU revision : 5 Hardware : Allwinner sun8i Family Revision : 0000 Serial : 02c00181e49e909a vs friendlyarm OS /proc/cpuinfo content: processor : 0 model name : ARMv7 Processor rev 5 (v7l) BogoMIPS : 22.85 Features : half thumb fastmult vfp edsp neon vfpv3 tls vfpv4 idiva idivt vfpd32 lpae evtstrm CPU implementer : 0x41 CPU architecture: 7 CPU variant : 0x0 CPU part : 0xc07 CPU revision : 5 processor : 1 model name : ARMv7 Processor rev 5 (v7l) BogoMIPS : 22.85 Features : half thumb fastmult vfp edsp neon vfpv3 tls vfpv4 idiva idivt vfpd32 lpae evtstrm CPU implementer : 0x41 CPU architecture: 7 CPU variant : 0x0 CPU part : 0xc07 CPU revision : 5 processor : 2 model name : ARMv7 Processor rev 5 (v7l) BogoMIPS : 22.85 Features : half thumb fastmult vfp edsp neon vfpv3 tls vfpv4 idiva idivt vfpd32 lpae evtstrm CPU implementer : 0x41 CPU architecture: 7 CPU variant : 0x0 CPU part : 0xc07 CPU revision : 5 processor : 3 model name : ARMv7 Processor rev 5 (v7l) BogoMIPS : 22.85 Features : half thumb fastmult vfp edsp neon vfpv3 tls vfpv4 idiva idivt vfpd32 lpae evtstrm CPU implementer : 0x41 CPU architecture: 7 CPU variant : 0x0 CPU part : 0xc07 CPU revision : 5 Hardware : sun8i Revision : 0000 Serial : 02c00081af9196e6 Armbian /sys/class/sunxi_info/sys_info file does not exist. vs friendlyarm /sys/class/sunxi_info/sys_info file content: sunxi_platform : sun8iw7p1 sunxi_secure : normal sunxi_chipid : unsupported sunxi_chiptype : unsupported sunxi_batchno : unsupported sunxi_board_id : 8(0) board_manufacturer: FriendlyElec board_name : FriendlyElec NanoPi-Duo2

Hi all, Running Armbian Ubuntu 18.04 with stock neo2 4.19.20 kernel I tried installing https://github.com/friendlyarm/WiringNP but after installation `gpio readall` says : "This NanoPi model is currently not supported." However all the wiki's and the Github page says it's supported.......? I can see GPIO in the sys fs at /sys/class/gpio/ but I was hoping to have an easier time with it than manually exporting each pin and calculating offsets for pins with scraps of info online etc. Objective 1: Read a high/low 3.3v/0v status from a GPIO Objective 2: Read an analog voltage, using an ADC. Does the H5 include an ADC? When I look in http://wiki.friendlyarm.com/wiki/images/d/de/Allwinner_H5_Datasheet_V1.0.pdf Page 13 says 2.1.4.9.KEYADC * Analog to digital converter with 6-bit resolution for key application * Maximum sampling frequency up to 250 Hz * Supports general key, hold key and already hold key * Supports single , normal and continuous work mode I don't need high speed sampling, don't need interrupts, the simpler and easier the implementation the better. Any help will be much appreciated PS: How to fix friendlyarm/WiringNP friendlyarm/WiringNP is not accepting issues on their github repo, but it seems to be the best fork out there. How can we get them to accept issues and how can we fix the issue? http://forked.yannick.io/friendlyarm/WiringNP

I'm running an updated armbian stretch mainline on a nanopi neo and hitting a wall where I thought there would be no obstacles in my path. I'm using 433Mhx Tx and Rx devices so I'm building WiringNP (from FriendlyArm) and rfoutlet (from github.com/timleland/rfoutlet.git). I'm getting errors such as wiringPi ISR: Not implemented when running RFSniffer. [This is the current error, it's been one after another]. My mind is muddled at the moment since I've done this kind of thing several times in the past on other devices including the Orange Pi Zero. Can someone tell me if this is me, or if it's a NanoPi Neo-thing? Shouldn't this be straight-forward? cat /etc/armbian-release # PLEASE DO NOT EDIT THIS FILE BOARD=nanopineo BOARD_NAME="NanoPi Neo" BOARDFAMILY=sun8i VERSION=5.65 LINUXFAMILY=sunxi BRANCH=next ARCH=arm IMAGE_TYPE=stable BOARD_TYPE=conf INITRD_ARCH=arm KERNEL_IMAGE_TYPE=zImage lsb_release -a No LSB modules are available.

All, I downloaded and built WiringNP according to the FriendlyARM instructions. Running 'gpio read all' gives me an error saying piBoardRev: Unable to determine board revision from /proc/cpuinfo for the rest the Neo Air Armbian runs fine. any ideas what's wrong?
