Re: Raspberry Pi 4 Thread - general discussion

Ok, from what I've read so far.....

It doesn't boot from USB
It doesn't boot from the network
So, it only boots from micro SDHC cards

It needs a different PSU, (using a different plug/socket)
It needs micro HTML cables
It needs a different case

Sounds like you may be just seeing the DOS partition - likely you are using MS Windows, which can't 'see' Linux partitions, (without extra software).

Re: How would I only boot into one program and not a full blown OS

Tiny Core Linux is maybe your best bet, but it isn't an easy system to set up for a beginner.

Otherwise, Raspbian Lite, & remove what you don't need.

Re: Unable to connect to a different wifi

I'm thinking that you set it up to access one wifi point, & now you need it to access a different wifi point, so you likely need to enter the ESSID & password of the second wifi point.

Re: Does anyone know technology for the PI to help people read?

Kano OS
That is a Debian based system, (as is SkoleLinux), so you will likely find what you want in their repositories.

https://packages.debian.org/stable/

You will just need to make sure it has been compiled to run on ARM.

From their website - https://youtube-dl.org/ The simplest case is requesting a specific format, for example with -f 22 you can download the format with format code equal to 22. You can get the list of available format codes for particular video using --list-formats or -F. Note that these format code...

Re: Cannot connect to WiFi if password contains "#"

Usually you can 'escape' a character by prepending a \ just before the character, but I'm not sure it will work with a password, you likely need to change or delete the password & enter a new one.

This may help.

Re: Boot from SD card or HDD?

A HDD/SSD will be more reliable in the long run, than a micro SDHC card.
If you're worried about the disk spinning all the time, use a SSD.
Powering disks usually takes more power than the USB ports can supply, so it is best to have its own power supply.

Re: Will adding an external SSD speed up Raspberry Pi?

Having experimented with all booting options, except netboot, the quickest to boot up is a micro SDHC card, mainly because the RPi always checks for it first.

However, once booted I prefer a SSD, HDD, micro SDHC, pendrive, in that order for their responsiveness.

(I use RPi3B/3B+/3A+)

You can also use a ? in place of the space in the name. I wouldn't. ? matches more than spaces. For example foo?bar matches foo bar, foo-bar, fooTbar, etc ? will work under some circumstance but nowhere near all. Nobody said that it didn't, the OP wanted a specific , & a ? will do what they want. (...

Re: Building laptops / computer for education raspberry pie

Cheaper to buy pre used laptops/netbooks in the long run, some can be had for the price of a RPi, (ex commercial used ones).

Most can boot from USB, so you could allow the kids to have their own personal pendrive, & collectively use the hardware on a time share basis.
