I had the same issue and it was just that the webdriver I had installed was for linux and when I changed it to ARM webdriver ( a bit older version ) it worked. The webdriver I used was: https://github.com/mozilla/geckodriver/releases/download/v0.19.1/geckodriver-v0.19.1-arm7hf.tar.gz. Also follow this blog and selenium automation will work smoothly for you....

The Reference is the initial download installed. It never changes and has nothing to do with current OS. See What OS version is installed if you want to know what you currently have.

I think no ,but i not 100% sure , i think it is not possible because at a time either u can join hotspot or create one , but u cant recive and send , but u can test with external wifi adapter so one can use as reciver and second one as transmitter or AP like wise wifi repeter do

Looking at how NOOBS boots may also help you. NOOBS basically makes the assumption that you have a FAT32 filesystem, and you just unzip the files to it. The Pi then boots as usual, but has an extra "OS" that serves to choose and boot into the real OS. For that matter, I'm fairly sure that's what NOOBS uses for the first-stage OS -- an initramfs. (I may be ...

Apart from the beta Microsoft emulator (https://azure-samples.github.io/raspberry-pi-web-simulator/), which only supports one built in circuit board, the only other emulator i could find is http://www.rpi-emulator.com/ provides an offline downloadable RPi-3 emulator for windows systems.

It is possible you changed something in your list of repositories or it may even occur from a corrupted file. When you run sudo apt-get update (or use the Refresh button in a package manager), a list of packages will get downloaded from the Ubuntu servers. These files are then stored in /var/lib/apt/lists/. If I'm ever having issues running update my last ...

The documentation you are referring to is a nicely written howto, I have used this approach many times and it works well. If you have wlan0 configured as a WiFi client to access the Internet, and use wlan1 as your access point interface, you basically just replace every wlan0 in the document by wlan1, and every eth0 by wlan0. Make sure wlan1 gets the ...

Try: Alt+F11 if on windows keyboard connected directly or remotely to the Raspberry Pi. If using Mac to connect remotely (via VNC or similar remote control), try Opt + F11 or Fn + Opt + F11. This combination toggle full-screen mode on or off and will therefore make the browser window that is hiding the taskbar become a normal window again and show the ...

I found a new recommended imager Etcher recommended by @HawaiianPi in this SD Cards issues thread. Etcher was able to image all the 3 cards without any hiccups and all 3 cards are booting in pi4 now. Win32DiskImager still doesnt work for me on the Buster image on the 16gb cards. Also etcher detected all the sd cards as having around 15.5 GB while both ...

I have had this same issue occur with the latest Lite versions of Buster, Stretch, and Jessie, on Pi 3 B+ with Edimax Dongles and onboard wifi, and Pi 2 B+ with Edimax Dongles. Something is wrong with the kernel relating to wireless drivers, but not sure how to capture the kernel panic to dig through it. I dug out an old copy of Jessie and avoided updates ...

The command sudo ./LCD-hdmi will run a script that uncomments the line hdmi_force_hotplug=1 in Raspberry PI Config File which will force raspbian to use HDMI instead of the touchscreen. If you do this, you will have to comment the line hdmi_force_hotplug=1 everytime you want to use your touchscreen instead of the HDMI. I hope this helps.

Here are some answers to your questions: Does the partition have to be on a specific location? I mean, is the 4,2MB of nothing before it necessary? The boot partition must be the first one. It doesn't matter where it starts. The very fist sector of the boot device contains the master boot record (MBR). You can show it with rpi ~$ sudo hd -v -n512 /...

You have already answered your own questions! 1) The Alpha Premiere marquee is designed such that you program the display content and format using either a purpose-built controller or custom software. 2) The manuals and catalogs that you referred to (on the Alpha American website) will tell you everything you need to know about how to control the marquee. ...

Your "solution" is the sledgehammer approach. Editing the sudoers file is not recommended. If you really want to do so it is safer to make a new entry in /etc/sudoers.d (which is used to give user pi passwordless sudo) If you want all users to be able to run a command setting suid permission is more normal. sudo chmod a+s /sbin/iwlist

Everyone thank you so much! I do not know how it is solved, i changed a lot of things, also reset network settings and rebuilt again. And finally, i get connection to putty, did update! ping still does not work but i am able to use mobile internet/wifi now. Now i should to disconnect raspberry now, going to continue tomorrow. I hope nothing will be lost.

As the output complains about "No access to /dev/mem", you could give access to the user running the script: sudo chown pi /dev/mem If your user is not pi, change the user name.

First you should append a bit mask to your ip addresses. Without it, it is assumed that you mean to use the whole class B network 172.16.0.0/16 with 65.536 ip addresses. But you have to ensure that the access point (wlan0) and the uplink (eth0) are on different subnets. Try to use this network files for the access point: cat > /etc/systemd/network/08-...

I found a solution although this is not the straightforward way to compile all at once.

My understanding is that there is new code required to support the RPi4 and that code is only delivered in Buster. If you need Stretch, you'll need to run it on earlier Pi hardware. You may get it to work, but why bother with possible limitations and degraded operation? If you have software that doesn't run on Buster, it's time to move it forward (or ask the ...

Nobody can answer this properly other than to say that anything sent to stdout or stderr will be discarded. What the application does besides that we don't know, but most likely all the output you are finding in the logs was captured from stdout/stdin. If you aren't familiar with the stdout/stderr abstractions, this is not just a linux invention but derives ...

You might need to specify some more details, but I suggest the following: First you need to make sure that you are connected to the same network. I'm assuming that by "Mobile internet" you are refering to WiFi. Connect to the same network. Open your Windows terminal and type ipconfig to see the IP Address of both your laptop and your Access Point (WiFi ...

It's absolutely about peripherals. The lowest hanging fruit for Pi 2/3b is the gpu if you are not using a display, then the usb/ethernet. The combined USB/ethernet chip consumes a couple of watts even when idle, and cannot be turned off reliably when the USB is on (I believe this may have changed with the 3b+). I believe there is a way to reduce this ...

The problem is not the firewall, your server is bound to the loopback address, 127.0.0.1. If you want to connect from other hosts, you must change the address to 0.0.0.0.

When you flash the Raspbian image, you should get 2 partitions on the SD card. The error suggests expanding the fs with the raspi-config configuration tool, as this is a usual setup step in setting up a new Raspbian install, as it will write on the disk, but won't utilise the remainder free space, until it is expanded.

The Raspberry Pi 3 and 4 have 64-bit CPUs. However, Raspbian is a 32-bit operating system, so that SD card images work on all Pi models. Depending on where you're looking, the Pi will report armv6 or armv7 (usually armv7) although it's actually running in armv6 userland, and despite the hardware is actually armv8. Some other operating systems provide 64-bit ...

Docker containers use the same kernel as the host. There are two pre-compiled kernels distributed with Raspbian, an ARMv6 one for the model 1's and Zeros, and an ARMv7 one for the multicore models. The latter works on the 64-bit ARMv8 models as well,1 since they are backward compatible. You cannot run a 64-bit userspace on top of a 32-bit kernel. While ...

Run the following sudo apt update sudo apt dist-upgrade -y That will pull in the latest updates to raspberrypi-kernel & raspberrypi-bootloader. If you've got that on your SDCard it will boot on a 3B+ or zero without any trouble. 3B+ is a Broadcom 2837 32/64-bit cortex-A53 processor (which uses 32-bit kernel7.img). The zeroW is the older Broadcom 2835 ...

The only thing you need to check is if the release date of your Raspbian image is NEWER than the release date of the hardware you want to use it with. The release date is in /boot/issue.txt. For hardware release dates you'll have to check Wikipedia. OLDER images will always fail to work without modification.

To save alias, you can use .bashrc file. .bash_aliases may not be available in every distribution. here is the code to make it persistent: nano ~/.bashrc go to the end of file and add your alias (also remember that there must be no space befor and after the equal "=" sign, since unless otherwise it would end up with error). alias checktemp='sudo /opt/vc/...

Your touchscreen works just as every other screen. I suppose you also had to connect an USB cable to your Pi. This acts just like a normal mouse.
