The Raspberry Pi 2 will give BCM2709 hardware and ~1 GB of RAM like this: pi@raspberrypi:~ $ cat /proc/cpuinfo | grep Hardware Hardware : BCM2709 pi@raspberrypi:~ $ cat /proc/meminfo | grep MemTotal MemTotal: 947756 kB while the Pi 1 reports BCM2708 hardware and definitely less than 1 GB: pi@raspberrypi:~ $ cat /proc/cpuinfo | grep Hardware ...

Additionally to the other answers, if you want to tell more than one pi of the same type apart, you can read the serial number in a similar way: cat /proc/cpuinfo | grep Serial Serial : 000000000000000d This will be unique per pi. More info: How do I get the serial number?

Or the noob way: poweroff one and identify the IP of the other, then you can guess the other IP. No matter which way you chose, if you want to go further and distinguish them easily in the future, you can change their hostname once identified. On each pi do the following: Edit /etc/hosts file: sudo nano /etc/hosts Replace "raspberrypi" in the file with ...

Ok, I fixed it. I just had to add a 1 in /dev/sda to make it read /dev/sda1.

Take the SDCard out, connect the power and see if either of the big chips get hot. If any part of your Raspberry Pi gets too hot to touch within seconds of you powering up the device then it's fried. The only way to fix it costs between $5 and $35 depending which model you buy to replace the corpse.

The rainbow square is an under-voltage warning. You might consider upgrading to a more powerful power supply (more amps, not more volts). EDIT To further answer your question I have tried to reproduce your issue. I have installed a new sd card with Raspbian Stretch and inserted in a B+. It boots normally and has been running ever since. Also after reboots....

Raspbian Stretch (all 3 versions) works on ALL model Pi, have published checksums, and is maintained - at least until superseded by Buster (and for some time after). NOTE There is no such thing as a Pi 1. The initial releases were Raspberry Pi Model A & Model B. There was a Raspberry Pi Model B Rev 2 and later releases increased memory to 512MB I have ...

The best I know is http://elinux.org/RPi_VerifiedPeripherals which you mention. I doubt such a list as you want will exist. The eLinux page covers 4 Powered USB Hubs 5 USB Remotes 6 USB Keyboards 7 USB Mouse devices 8 USB Real Time Clocks 9 Internet 9.1 USB Wi-Fi Adapters 9.2 USB Bluetooth adapters 9.3 USB Ethernet adapters 9.4 USB 3G ...

I'm pretty sure one of the numerous barriers you may be facing is that the Pi 3 uses arms v8 architecture and the Pi model 1 uses arms v6 architecture. Which kind of makes what you're trying to do impossible without integrating multiple kernels into one os and having the system choose which kernel to use on boot.

You have a number of choices. ignore the warning switch RPi.GPIO warnings off (see its documentation) don't use GPIO 2/3 (pins 3/5) which have the hard-wired pull-ups

From your download tests there seems only one possibility to be left over. The ip forwarding between wlan0 and wlan1 could be limited. You are using a Raspberry Pi 1 model B. This is one of the first models ever. There are newer models with more performance. It has no wifi chip on board so you use two USB to wifi dongle for your wireless networks. Both ...

Use the program Etcher with a so-called image file. All your settings , installed programs and documents will be saved if you do a proper shutdown from the "Start" menu (it is called something else on Raspbian , but you get the idea). Get image files for "Raspbian Stretch Desktop ZIP" here . I strongly recommend Raspbian , it is the best supported distro ...

The raspberry pi was never really intended as a machine that you would use for everyday desktop computing tasks. It's more of a hobbyist machine for people who want to build do-it-yourself projects like a weather station, or a retro gaming console. For comparison, I tried starting up Chromium on my pi-zero, which is a 5 years newer and has a 40% faster ...

You also asked: "Maybe you got even hints for a better solution in general." I prefer to use systemd-networkd because it has all in one. Using two USB/wifi dongle simplifies it a lot. So my hint is to look at Access point as WiFi repeater with additional WiFi-dongle. It does not fit exactly your needs but it should not be a big problem to adapt it to your ...

I specifically reactivated my never used account to answer this question, because I was having the same problems last week and felt like other people will too./rant About the actual problem, using the explanation about ssh from Can a Raspberry Pi be used to create a backup of itself? misses a crucial point - rsync does not properly preserve the ownerships (...

You don't use a docker image. It's just a plain Raspbian image you use. There is one important step you have to execute when you copied the image on the SD card: Enable ssh access. See Enable SSH on a headless Raspberry Pi

I have exactly used the same instructions also with predictable network names to configure my test setup. I use a Raspberry Pi 3B+. To ensure that we have the same environment as most as possible I use the on-bord WiFi chip to make the access point and my USB/WiFi dongle to establish the uplink client connection to my internet router. Everything works as ...

Most likely a mismatch between /etc/fstab and /boot/cmdline.txt. Other possible errors are a mismatch between the kernel version and modules. The process was designed to BACKUP and RESTORE to the SAME SD CARD - not a new image. It was also written before the adoption of PARTUUID. If you overwrite the boot partition with the contents of that on the old ...

I solved the problem. (I couldn't really believe this to be a performance issue.) It seems that the problem was interference between wlan0 and wlan1, although they are using different channels (1 and 6). After changing the position and orientation of the dongle providing the hotspot, the download speed on my pi and my device has become almost the same.

Use GUVCView. sudo apt-get update sudo apt-get install guvcview This program only works with USB cameras.

I had trouble running gitlab on 2 GB RAM 1.2 GHz HP ProLiant. It uses a lot of resources to run. If you can do without the fancy GUI, you could just install the git core on your RPi create a bare repository that you can then push to just like you were using github or gitlab.

I have tested it with uploading a single 300MB file to nextcloud (no encryption enabled): Upload Speed with Pi 1 as reverse proxy: 3-4 MB/s Upload Speed with Pi 2 as reverse proxy: 9-10 MB/s Upload Speed with no reverse proxy (direct access to Pi 3): ~12MB/s (nearly full 100MBit/s) So the Pi 1 as reverse proxy have an impact on the network speed. For ...

If you are already using putty take WinSCP. An alternative is (for private use free) bitvise-ssh-client which also offers a dual paned file transfer window.

FTP would I think be your best bet here. If you expect that no one else but you (or those with access to sufficient priveleges) will be transferring files to your Pi, then the sftp-server that came installed your Pi should suffice. Otherwise, you may want to install Pure-FTPd. There's good documentation here: https://www.raspberrypi.org/documentation/...

By using a the spotify plugin for a computer with Kodi, I signed in to spotify and a file named "USERNAME.cache" got created under .kodi/userdata/addon_data/plugin.audio.spotify" I copied this file over to my raspberry and from then on the spotify plugin works. My Pi is v1, with LibreElec7, it is slow but I just streamed my first spotify track. PS: I am ...

It us EXTREMELY unlikely that there will be drivers for the ARM6 processor on the Pi! All the drivers you need for most WiFi devices are already built into the kernel. Not all WiFi devices/drivers support AdHoc modes. I suggest you get the WiFi working as normal FIRST, then try your project.
