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...
Thank you for the reply. No luck for me: pi@RWPi:~ $ sudo pip install --upgrade requests Exception: Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/pip/basecommand.py", line 215, in main status = self.run(options, args) File "/usr/lib/python2.7/dist-packages/pip/commands/in...
I just installed 2017-09-17-stretch and seeing lots of errors when attempting a pip install speedtest-cli. Any clues? sudo pip install speedtest-cli Collecting speedtest-cli Exception: Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/pip/basecommand.py", line 215, in main st...
I successfully installed 2017-09-17-stretch (full) headless with wpa_supplicant.conf: country=US ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev update_config=1 network={ ssid="MYWIFISSID" psk="MY11CHARPASSKEY" key_mgmt=WPA-PSK } When I try to update, it is using IPv6 $ sudo apt-get update 0...
Edit: A quick Google search shows maybe you should use an app named TextEdit instead of textapp. TextEdit is the editor I used. I discovered my problem: I had copied the text from a web page and pasted it into TextEdit. The quote chars from the web were the Unicode left/right double quote!! My old,...
I use Python on my robot. There are great open source examples of Python available for the GoPiGo robot. BTW, GoPiGO is a well designed robot, with excellent forum for their users, and educators. If I was starting out to build a robot again, I believe the GoPiGo is the best platform and support syst...
Is there a power cell or a power pack I should look for in particular for this issue? To give good suggestions, we need to know a little more about your robot, such as: 1) Which Raspberry Pi board are you powering? 2) Are all the motors/servos powered separately from the Pi board? 3) How much run t...
Did you not read my posts? I just did two headless installs that went fine. "Works for me" really doesn't feel good to those of us that are seeing this issue. You may be onto something about what editor is used to create the wpa_supplicant.conf file. My recent headless stretch flogging seems to sha...
Anyone know if there is a work around mirror? You could (temporarily) change the URL in /etc/apt/sources.list to one of the mirrors: https://www.raspbian.org/RaspbianMirrors http://mirrordirector.raspbian.org/raspbian/ is not working for me at the moment, so tried: deb http://raspbian.mirrors.wvsta...
I just finished two days of flogging with "wlan0 not associated" with 2017-09-07-raspbian-stretch on a Pi3 that was playing nice under jessie-lite. I tried the headless method with: wpa_supplicant.conf per the thread head: country=US ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev update_con...
solid aluminum case Indeed, that worked very nicely till I wanted to add a LIFePO4 UPS to protect my SD card from power failures. Pi3 is mounted vertically (on edge) in free air. A 15mm cube heat sink is stuck on with 3M thermal tape. That is how I was running with the UPS until I came home and fou...
I am wondering if optimal processing on my Pi3 might result from allowing short bursts of temperature caused throttling. I have been running Einstein@Home/BOINC on my Pi3 with load limits tuned to prevent temperature throttling. At these settings, the temperature hovers around 71 degrees C, and will...
For some reason "Screen Sharing" app from my Mac Mini (OS 10.12.6 Sierra) started reporting that that "version running on remote computer is incompatible with Screen Sharing". It seems like a crash had left some droppings in /tmp/.X11-unix/ To fix it, I did the following: ssh pi@ip.of.rpi ps -ef | g...
On my robot, I use the 5v RPi for vRef (and VDD) on the 3008, and only level shift the DOUT (using r1.r2 divider) from the 3008. The I2CS, DIN, CLK from RPi (3.3v) go straight into the 3008 no problem, no level shift needed. When running the 3008 with 5v ref, there is no need to level shift your 0-5...
I've been running BOINC projects on my Pi3 at an average load of 2 and 70-74C, powered at 4.97v at the header for the last 18 days with no problems. I updated the OS last night, and rebooted, which started BOINC processing again. Roughly eight hours later, while showing the same load, temps, and vol...
