  1. Thanks @Guidol, I had the same issue with Orange Pi Zero Plus. One showed Cpu Temp And Cpu Frequency. Two did not show the options. ~/.config/htop/htoprc was blank on the two that did not work. Changing settings on htop did not populate the file and settings were lost between sessions. File permissions were the same for all three. I copied the working htoprc to the other two and this solved the problem.
  2. If you use a SIP Voip client on your phone or computer, you can use the sip protocol and scripting to monitor your Armbian board. I'm using Ubuntu Xenial, but other versions should work as well. I have the Linphone client on my phone and I use the free Linphone SIP service. Linphone.org hosts a free SIP service that allows users to make audio or video calls using SIP addresses via the domain sip.linphone.org. You can also send text messages. SIP requires an internet data connection, and my phone is connected via WIFI most of the time except when I'm commuting,
  3. How to install Puppeteer on node.js on Armbian. Tested on OrangePi Zero Plus running Ubuntu Xenial or Bionic. Should work on other boards and other builds. How to install the latest version of node.js. (at the time of writing was 12.7.0). Instructions for installing node.js on Debian and Ubuntu can be found at: https://github.com/nodesource/distributions/blob/master/README.md#deb The instructions at the time of writing were: # Using Ubuntu curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash - sudo apt-get install -y nodejs # Using Debian,
  4. Orange Pi Zero NTP Stratum 1 PPS GPS Server with Armbian OS. Link to the Tutorial - http://schwartzel.eu3.org/ntp-stratum1.html This tutorial uses a 3.3V capable GPS module with PPS output - TOPGNSS GN-701 (u-blox 7) but other similar modules should work. This tutorial is for the Orange Pi Zero, but will probably work for other boards. I couldn't easily do a comprehensive hardware and software tutorial on this forum, so I've published it on my web server and linked from here and attached a PDF.

  6. I posted in "Armbian build framework" when it should be in "Allwinner A64, H5 & H6". (It might be useful for other newbs like me if in the right place) https://forum.armbian.com/topic/8192-where-how-can-i-edit-boot-environment-on-the-spi-nor-flash-on-zero-plus/?do=findComment&comment=61853
  7. Thanks martinayotte - it is working now. I'm describing this for other newbs who might struggle to find these things. Your referenced patch has pointed me to "arch/arm/mach-sunxi/usb_phy.c" which I found in my Vagrant build environment at "/home/vagrant/armbian/cache/sources/u-boot/<version>/" The line "static int initial_usb_scan_delay = CONFIG_INITIAL_USB_SCAN_DELAY;" exists so it looks like the referenced patch is now a part of the build. I found the u-boot configs under "/home/vagrant/armbian/cache/sources/u-boot/<version>/configs" and the one for my b
  8. I'm a newb, so please make allowances if I am a little dumb. I have SPI NOR boot working on an Orange Pi Zero Plus (H5). Latest next kernel. (I've tried the download, and compiled my own).

  9. Is there a way to modify the uboot scripts? I want to try doing a usb reset or delay before the usb start. When the device fails to boot after a power up at the uboot prompt, I type: usb reset => usb reset resetting USB...

  10. I found some clues in this forum, and realized that it was probably a buggy version. That's why I tried the latest version and it worked. https://forum.armbian.com/topic/5218-spiusb-boot-orange-pi-pc2/?tab=comments#comment-39741
  11. I tried with the uboot from Armbian_5.59_Orangepizeroplus_Ubuntu_bionic_next_4.14.65 (the latest that I could find). It worked better and booted into uboot but I now have one problem: It didn't find my USB drive until I reset the CPU starting USB...

  12. I tried flashing the concatenated sunxi-spl.bin u-boot.itb to the uboot partition mtd1 (from instructions elsewhere on this forum) https://forum.armbian.com/topic/5218-spiusb-boot-orange-pi-pc2/?tab=comments#comment-42665 The flash worked. apt-get install mtd-utils cat /usr/lib/linux-u-boot-next-orangepizeroplus_5.38_arm64/sunxi-spl.bin /usr/lib/linux-u-boot-next-orangepizeroplus_5.38_arm64/u-boot.itb > /usr/lib/linux-u-boot-next-orangepizeroplus_5.38_arm64/u-boot-sunxi-with-spl.bin flashcp /usr/lib/linux-u-boot-next-orangepizeroplus_5.38_arm64/u-boot-sunxi-with-
  13. Success! Many thanks for your help. I logged in as root and followed your instructions slightly modified: Modified source with only two partitions (only the first is used). apt-get install flex apt-get install bison git clone https://github.com/pantoniou/dtc.git cd dtc git checkout dt-overlays5 make PREFIX=/usr make install /root/dtc/dtc -@ -I dts -O dtb -o /boot/overlay-user/my-spinor.dtbo /boot/overlay-user/my-spinor.dts reboot cat /proc/mtd This produced: dev: size erasesize name mtd0: 00100000 00001000 "env" mtd1: 00100000 00001000 "uboot"
  14. I was able to install the dtc compiler with symbol support after installing flex and bison. The "-@" parameter was not recognized, and gave Error: unknown option. It is not listed in the help output. As this is for symbol support, I am pretty sure that this is caused by it using the wrong dtc compiler as there is one already installed without symbol support. I will try and figure out how to fix this.
