Backup your SDcard, and do testing with fresh install. Maybe worth giving it a try if it fixes it: https://forum.armbian.com/topic/12403-opi-zero-xr819-wifi-broken-in-new-builds/?do=findComment&comment=91259 If above doesn't help: Disable network manager (permanently) to avoid it restarting after a reboot: systemctl disable NetworkManager.service Configure your network "old school" /etc/network/interface and test again. Last but not least analyze your logs, here is the how to: Providing logs with armbianmonitor -u significantly raises chances that issue is getting addressed.

my very first SBC (Lamobo R1) is finally completely FLOSS (free libre open source software) supported So to say the best product from SinoVoip, sadly I never received an answer from @Nora Lee @Lion Wang about my suggestion especially point 1 & 2 would be easy and a huge improvement of the hardware. in November: https://olimex.wordpress.com/2019/11/28/a20-and-a64-olinuxino-now-with-libre-elec-and-kodi-support/ and just a couple days later: https://olimex.wordpress.com/2019/12/20/the-a20-driver-for-hdmi-audio-is-almost-done/ https://www.olimex.com/

Providing logs with armbianmonitor -u significantly raises chances that someone is looking at it. // sent from mobile phone //

why do you need this?

only a man's year work, full time, for one (1) mobile. That's it So, if you have some time start programming.

in the past some installation broke during the Update. To improve stability some parts have been decoupled. Since then u rarely read about update problems // sent from mobile phone //

Troubleshooting, USB (cable) works Ethernet cable (your printer has one, right?) WiFi, but WiFi on OPiZero is tricky, see below. Once No. 2 works your network is not blocking it - get this sorted out. Do not start with WiFi until that works. If you are using the 'onboard' WiFi of your OPiZero, then try to disable that. Take an USB-WiFi-Stick (borrow one from a friend) test it with this first, because onboard WiFi-Driver is nowhere stable: https://forum.armbian.com/topic/12403-opi-zero-xr819-wifi-broken-in-new-builds/ Last but not least, please report back

You must read the first post, before you start: https://forum.armbian.com/topic/7930-armbian-for-amlogic-s9xxx-kernel-5x/ hold on, when you read the first post here DO NOT START.

A nice video about really tweaking boot time. You must have a really special, rare case to use that technic, but if you have the need to boot linux as quick as a microcontroller, then it is quite interesting Timing Boot Time Reduction Techniques - Michael Opdenacker, Bootlin https://www.youtube.com/watch?v=6sUiDJlJiYw&feature=emb_logo 39 min

I don't know what tickles your interest, but is it worth to add a 4th or does it make sense to improve the ones already here ?

a 2 minute video about how to report a bug on https://launchpad.net/ (Ubuntu) quite interesting and I didn't know about ubuntu-bug. Pretty easy, good to know: https://youtu.be/27OhY83MsU8

armbianmonitor -u tells the reader all the details about your Installation, like Kernel-Version and much more, please post the result of this command.

Hi Guido, Thank you. As you mentioned several components I wasn't sure what is really needed and to install was a bit overkill, at first sight. I could have gone ahead with try and error, but as you already have the knowledge, I thought it was better to ask. Apart from that, others can now also easily benefit from your lesson 😊 Cheers, Tido

This library aims to create simple wrapper functions for accessing I2C, SPI and creates a consistent numbering scheme for accessing GPIO ports based on the physical pin number.

There are 3 options to use GPIO in armbian: https://forum.armbian.com/topic/9071-opi-zero-plus-h5-and-gpio-library/?do=findComment&comment=68424 By the way, what do you control with the GPIO on R1?
