This worked for me this morning: Motion for Raspberry Pi sudo modprobe bcm2835-v4l2 sudo /etc/modules to add: # camera with v4l2 driver bcm2835-v4l2 reboot sudo apt-get install motion sudo cp /etc/motion/motion.conf /etc/motion/motion.conf.bak sudo nano /etc/motion/motion.conf to change: rotate 180 ...
Anecdotally, when I have two RPi3 on the same subnet (10.0.0.x on US channel 6), or even same subnet, different WiFi networks (SSID1 and SSID2 in same room, two routers on different channels - US 3 and US 6) I often see: sudo apt-get update Ign:1 http://archive.raspberrypi.org/debian stretch InRelea...
Why did you use rpi-update? It's not recommended for casual users. I was warned "Or for the brave and foolhardy", in a suggestion in response to my Pi3 built-in WiFi frustrations. If you are giving feedback for experimental software then you'll need to provide much more information than 'this versi...
After I did an rpi-update this morning, my robot couldn't move and felt weak (no motor PWM and couldn't SPI to the Analog Digital Converter ). I reverted the firmware and my robot feels much better again. This one works: uname -a: Linux RWPi 4.9.41-v7+ #1023 SMP Tue Aug 8 16:00:15 BST 2017 armv7l GN...

added to /etc/rc.local: iwconfig wlan0 power off resulted in my Stretch Pi3 onboard wifi power management being permanently off. For my robot, this reduces the tx excessive retries by a factor of 10, and incoming ping Request timeouts by a factor of 2. Linux RWPi 4.9.41-v7+ #1023 SMP Tue Aug 8 16:00...
Recently my robot suffered its second "read-only" SD card failure. At the moment, if my robot detects that it only has a few minutes of life left, it executes an os.system( "sudo shutdown -h now") Is shutdown -h now safe to issue? The robot launches several Python processes to manage sensor readings...
My robot has a (new) Pi3 running updated Raspbian Stretch, with a remote ssh session over wlan0, and a Python2.7 multi-process sensor status loop running, with a 15 minute top load of 0.10 When I ping the bot via WiFi, I see about 10 "Request timeout for icmp_seq x" per hour. With power management o...
Not normal Thanks. And for all your assistance in chasing the WiFi issue. I ordered up a new Pi3. This is the second Pi, out of four, my robot has messed up. I keep trying to enable it to be more capable, but it seems to be resisting artificial intelligence. (It began “life” 18 years ago with 32k o...
I have been used to waiting for the 10 blinks on shutdown of jessie-lite. I'm on "full" stretch now, and seeing the green LED flash 30 times on shutdown. Is this the new normal, or has my Pi gained consciousness and is trying to tell me not to shut it off?
Do you plan on using two wifi devices? If so, you should use persistent network names. Otherwise, it is almost impossible to tell which names they will use. How is the signal after you reboot? Use iwconfig to check. Plan: No I don't want to need the dongle, but the on-board is no long working well ...
Issue: Intermittent WiFi over built-in Pi3 interface, "Release file not found" on apt-get update Work-around: Use USB WiFi dongle (or wired Ethernet) for wlan0 (try reboot again if dongle configures as wlan1) Aspects: ifconfig shows no packet errors or dropped packets. Issue seen on Jessie, jessie-l...
I didn't see a BOINC project thread - sorry if this is a dup. I have a desktop Pi3 which has nothing to do for most of the day, so I installed BOINC and joined the RaspberryPi team running Einstein@home tasks. I also configured 25% of my BOINC processing to go to the SETI@Home project. Originally, m...
It appears this particular Pi3 may have developed a built-in WIFI problem. It was working fine for the prior six months. Then I had the SD card go "read-only", and now this. I tried curl http://mirrors.ocf.berkeley.edu/raspbian/raspbian/dists/stretch/Release. On my mac it succeeds. On my DeskPi3 it ...
Someone, please tell me what is wrong in my world? This is the Stretch experience: 1) downloaded 2017-09-07-raspian-stretch.zip 2) put it on 16gb card with Etcher (using Mac) 3) Pull out, reinsert card to mount boot partition 4) add wpa_supplicant.conf to boot partition: country=US ctrl_interface=D...
I don't think this is a DNS issue. When I browse the archive, the armhf package really does not exist - only binary-armhf exists, in both main/ and ui/ Err http://archive.raspberrypi.org jessie/main armhf Packages 404 Not Found [IP: 93.93.135.188 80] Err http://archive.raspberrypi.org jessie/ui armh...
Okay, that got me curious, so I made two freshly imaged SD cards with the last Jessie and the current Stretch and tested them both in my Pi Zero with a Raspbian compatible USB WiFi dongle. This leaves me wondering if you are having DNS issues with your ISP? Try changing your DNS to OpenDNS or Googl...
Going back to Jessie is actually a fine option, Actually, something too weird - 2017-07-05-raspbian-jessie complains about the same files missing, and tries IPv6. The IPv4 issue I can fix, but the missing files on a clean install, makes me question the repositories: $ sudo apt-get -o Acquire::Force...
My "jessie-lite" robot recently had its SD card turn read only, so I decided to try rebuilding it on Stretch. The initial hurdles make me wonder if my 17 year old robot should wait until Stretch gets over "growing pains". The first two steps in my build process are: 1) update the OS 2) use pip to in...
