Thinking to install Eclipse IDE on my RPi 4, I checked. I tried lshw to list all the hardware, and it reports.. description: ARMv7 Processor rev3 (v7l) product: Raspberry Pi 4 model B Rev 1.1 serial: 100000007535ef8 width: 32 bits capabilities: smp Eh! ?? The review said the processor was a Broadcom...

RonR: More thanks. This time I got there! There are many little situations that can arise.. Clicking on the shell script icon, and letting the GUI offer a choice to "Run" or "Run in Terminal" is what tripped it up. As in your post, the right way is opening a terminal and using sudo ./usb-boot, which...

Much simpler and less error-prone: 1. Write a Raspbian Buster image to your USB drive with Etcher . 2. Write a Raspbian Buster image to an SD card with Etcher . 3. Plug the USB drive and SD card into Pi4 and boot it up. 4. Run usb-boot , answering 'No' to 'Replicate BOOT/ROOT contents from /dev/mmc...

Thank you Pi 4 folk for the great Pi 4 USB boot recipe and advice. Now suppose the USB drive happens to be a 500GB USB 3.1 SSD (like Samsung T5). Simply plugging it in (experiment) causes a mounting error (:unknown filesystem 'exfat'). I know it's a Microsoft thing, but my LinuxMint seems to treat t...

Hi all After quite a long time away, I finally got back to the Pi, this time a Pi 3 with a Sandisk SD card that was fast enough not to limit the performance. And - while getting curious, a thing from the long past shows up. I loaded up RiscOS on the Raspberry Pi 3, and I was blown away by the perfor...

Can one invoke OpenGL ES or OpenVG from such souces, and what does it take? Use a OpenGL ES Wrapper/toolkit like JOGL. http://jogamp.org/jogl/www/ ghans Thanks much for the suggestions ghans. Probably with a mix of direct experimentation, and searching out what techniques various folk have used, I ...

I am new to PI, but what I am trying to read up about does not quite fit in beginner's section. It would be great to get a bit of an overview of how the common programming languages and resources can best be applied to use the built-in features in the Raspberry Pi. There are so many acronyms, librar...

On *nix a fix is tr -d "\240\302" <file >file.new Should copy file to file.new and remove those unneeded characters. Thanks Joan - indeed it does. We can understand that that most browsers have to be able to recognise and handle all the many flavours of EOL newline combinations, but this is not tru...

Thanks also topguy It looks more like a UNICODE / UTF-8 character set problem. \302\240 is in hex 0xc2 0xA0 which is in this table http://www.utf8-chartable.de/ mean NO_BREAK_SPACE. Being in the UK, I used (as root) raspi-config to set the Locale to en_GB.UTF-8 UTF-8 , which is the recommended choic...

My thanks for the reply. Yes, the numbers in there might indeed be associated with CR and LF escape codes, but I am not completely sure. It begs the question about spaces. I thought a SPACE character ASCII is the same in DOS as well as UNIX formats. The only difference I am aware of is that DOS form...

This is a difficult thing to describe since copy-paste is needed to show examples, but I will try. The Pi is like any other, with Raspbian downloaded last month. The problem came when using copy-paste with using LeafPad (or Nano) to make a simple bash script to try out the vcgencmd commands to explo...

Thanks very much for the help. The .zip did in fact unpack OK I went back to the SD card, and this time, I tried for Raspian. It worked OK. What (I think) has happened is that (perhaps temporarily), Raspian is the only distro available, despite a main feature of NOOBS being to allow relatively painl...

I had an older Raspberry Pi which came with a pre-loaded SD card, worked OK, and has been given to a child. This time, with a newer model B, I tried downloading the NOOBS .zip file to then put on a SD. I have the kit to write to the empty SD card, and it all went well enough for the NOOBS configurat...
