In /usr/share/agnostics/sdtest.sh add --max-jobs=4 as an argument to the FIO invocation. Seems to cut RAM usage by a drastic amount. Thanks @jdb - I'll give that a try with raspiblack (Pi #1) sometime later today and report back. At some point I'll test with raspigrey , my model A Pi, too. Trev.

I just ran the new SD Card speed test on my fleet of Raspberry Pi's.
Must have missed some announcement somewhere - what new SD Card speed test?

See the March 4th. blog: https://www.raspberrypi.org/blog/sd-card-speed-test/

I've learned a lot, but still a newbie. I am trying to make my Pi 4 a NAS and am almost there, but I need some help. When I start Raspbian Buster on my Pi4, my USB drive shows up on the desktop. According to file manager, this USB drive is mounted at /media/pi/NAS2. Samba is running, but Win10 cann...

Trev, most people would call that a protoboard, not a breadboard. Maybe so - names and definitions change. When I was building audio pre-amps around germanium transistors (OC71, OC81 etc.) one used tag-strips or pins in matrix board (veroboard w/o the copper strips) those were breadboard(ed) protot...

They should not fall out. Can you post a link to what you bought? +1 However, if it's similar to this: https://www.cpmspectrepi.uk/raspberry_pi/MoinMoinExport/AdafruitRasPiPermaProtoFull.html then it's one for "permanent", soldered circuitry usually built after testing with the "plugin" type. (In m...

With default configuration it runs really hot with out fan or heatsink. No programs running. Why? What is it doing? How are you measuring the temperature? Its usually done with:- vcgencmd measure_temp With nothing running, my Pi4 idles at around 35C depending on the room temperature. It might idle ...

What you are asking makes no sense. You are absolutely right in that I forgot to point out: No, I do not actually want to disable VNC (I'd know how to do that). I just do not want that VNC Connect app not to start. It autostarts after each reboot when I log in via VNC. I can quit it, and the VNC co...

@olivero & @gordon77 thanks for the info. AFAICT, so far, 04d9:0006 refers to the Holtek/keyboard/hub (RPI Wired Keyboard 1) combo. whereas 04f2:0963 Chicony Electronics Co., Ltd (2.4G Multimedia Wireless Kit) which seems to be the keyboard/hub (HID devices) is "something else" possibly the similar ...

Just to clarify, this is a Raspberry Pi problem, not a user problem. I used Raspberry Pi Imager to get the latest Raspbian Buster. I plugged in the latest UK Raspberry Pi keyboard (the one with the integrated USB hub). I did not select the US keyboard in the setup. But the pi was configured for a U...

Just tested this on my two first generation Pis - both have trouble. On the 512MB version it is rather more serious - the whole Pi hangs hard and needs the power yanked to get it working again. The 256MB version seems to just have heavy load for a few seconds, then goes back to normal. Both fail to...

Folks, Curious, I run a few headless Pi projects so invariably use the lite version of Raspian. I nearly accidentally enabled VNC on the lite version recently and it stated 168MB of space would be needed. Without a desktop is this of any use? Geoff Possibly not but for someone like me who has Pi's ...

O.K. I've used a P3A+ running the Pi version of the new Imaging Tool to write a 16Gb uSDHC card to be used in an adapter for my original B1 256Mb Pi - raspiblack: https://www.cpmspectrepi.uk/raspberry_pi/MoinMoinExport/BlackAndBluePis.html Buster runs fine but, of course much slower. With SSH enable...

Try changing the File Manager's Volume Management settings - same location as for disabling auto-mount altogether:

I use old cards like that to build up systems for testing stuff out on. I can install a fresh Raspbian on them, try stuff out, then re-write them as required when it goes wrong. That is a decent idea,, I do have one of those plastic holder that store 8 microSD cards, don't write on the labels, just...

Same reader/writer as where I flashed my Pi3 64GB card with. That works fine (only not in the Pi4 off course). Despite the fact that the card tests are positive, I do think it's the SD card. It also does not boot in my Pi3. Given that you appear to have a working P3 maybe try updating that and usin...

So I can be 100% certain that a 4.5A battery won't do anything harmful to the Pi? Sorry, no - the current capability (w.r.t. to being "harmful") is largely irrelevant - it's the voltage output that's important. However I would not recommend any "random" battery (pack). You need a proper USB C power...

This may be a "red herring" but when I last played with USB-to-TTL (3.3V) adapters connected to a Pi the default setting was 115200-8-N-1. However, IIRC, that can be changed in /boot/cmdline.txt : https://www.cpmspectrepi.uk/raspberry_pi/MoinMoinExport/USBtoTtlSerialAdapters.html Currently, on the P...

Is your Pi a 3A+ or just an A+? The latter was made in a 256MB version.

FWIW, here are links to pictures etc.:
A+ : https://www.cpmspectrepi.uk/raspberry_p ... RasPi.html

OK, still getting nowhere. :( I've had a look at the docs. This one: https://www.raspberrypi.org/documentation/configuration/hdmi-config.md appears to say that setting the mode is done with hdmi_mode:0 or hdmi_group:1. But my config.txt (and everything else) is hdmi_mode=0 or hdmi_group=1. I assume...

Having looked up what a Prolite E4355 display is it appears to use a DVI input rather than HDMI... Also has a VGA input: I'm using a HDMI-VGA adaptor. It displays fine, so I think it's working on that score. Have a couple of things to try now, I'll report back... Hint: what do these tvservice comma...

.... What are you using as a HDMI display - monitor, T.V. or other? Was it that giving the "no HDMI signal" message itself? Trev. ** https://www.raspberrypi.org/downloads/ So I used a monitor and 3 different tv's. Also the O.S. is Pi compatible because it already worked as i said. Nevertheless ill ...

Hi folks, last wednesday i got my raspberry pi 4, a proper hdmi kable (no adapter) and the original power cord. Then I installed Kali Linux and tried it for the first time. The Pi was on but it had no HDMI output. I wabbled a bit on the black thing over the sd card input and it worked. But 2 days l...
