Re: Learning C++ on my Raspberry Pi!!

Re: What is the recommended screen size and resolution for software development using Pi3B+ or Pi 4?

I haven't tried 4K myself, my understanding is that it's possible to do 4K on older pi models but only at very low refresh rates. 800x480 I would say is too low for comfortablly running most modern desktops. 1366x768 or 1280x800 is about the lowest I would consider acceptable for a deelopment system...

Re: The point of 4 MiB padding between partitions?

I'm guessing this is a bug in the script/tooling that generates the partitions.

The start and end sectors displayed by fdisk are inclusive. So the first partition is 256 mebibytes and one sector in size. The second is 3072 mebibytes and one sector in size.

Re: Ethernet cable as Wifi antenna

My guess as to what is going on: The metal case blocks the onboard antenna, but some RF inevitablly leaks from the radio circuits to/from the rest of the electronics. The power cord is essentially connected to the system ground which is connected to the metal case, so it can't really act as an anten...

Re: experimental support for multiarch with Raspbian and Debian arm64

When a "multi-arch: same" package is installed for multiple architectures under multiarch, the version number for the package on the two architectures must precisely match. For most packages, the version numbers do match, so (provided the package is multi-arch: same) the regular Debian arm64 package...

Re: ATX PSU breakout board not powering on issue

Re: "Introducing Raspberry Pi Imager, our new imaging utility"

That is so wrong Debian with RDP IS an .ISO: It is an ISO9660 DVD image, it's also a bootable image for USB sticks and similar. This is possible because ISO9660 reserves a 32K system area at the start of the drive. That is more than enough space to fit in a MBR boot sector and partition table for l...

Re: CM3+ - Connecting LAN9512, but also get USB Slave functionality?

The controller on the BCM283x can't be both a host and a device at the same time. If you want both host and device functionality, but not at the same time, then you will need to use a USB mux IC, like the FSUSB42UMX used on the CMIO board triggered by the VBUS on the slave connector. You probablly a...

If you didn't add the 386 architecture it follows someone else did.
Someone or something.

There are lots of software installation scripts out there intended for debian/ubuntu amd64 systems that will add i386 as a foreign architecture.

Afaict there are two main reasons for NOOBs. 1. To allow a Pi SD card to be set up on a machine where you can't/shouldn't install software and/or don't have admin rights to acess raw disks. 2. To allow users who don't have the ability to write cards themselves a means to reset their system when they...
