Re: NOOBS refusing to move onto the pi

Is there really any point to using NOOBS/PINN if you go the "install it as an image" route? NOOBS - debatable. RPF don't provide an image for it anyway. PINN - Absolutely! Times have changed. The size of SD cards has increased dramatically since the 2GB SD cards I used on my first Pi 1B and the cos...

Re: Arch Linux ARM not booting on Pi 4B

The only bootloader compatible with PINN would be NOOBS, but that's a bit of a backwards step. And anyway, it's not really a "boot loader" in the usual sense, more of an "OS selector at boot". What is your issue with wanting to change it? Do you want a faster startup of Arch without PINN getting in ...

The official instructions for installing Arch on a Pi 4 are here -> https://archlinuxarm.org/platforms/armv ... berry-pi-4 , on the installation tab.

Both Manjaro (KDE or xfce versions) and Arch4 can be installed by PINN.

Re: NOOBS refusing to move onto the pi

IMHO, if someone insists on using NOOBS on a card >=32GB in size of any size, then the easiest, foolproof method of installing it is: 1. Switch to using PINN-lite 2. Install the image version of PINN-lite using RPI Imager (see https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=142574&start=975#...

I just managed to get a micro hdmi to hdmi adapter and the screen is stuck at the rainbow screen. Do you mean in NOOBS or in some OS like Raspbian?

Re: Exterior Gate Alarm, Horse Farm, Wireless

The ESP32 is a more powerful ESP8266, so you can use either of these. This article suggests you can get 366 metres on a PCB antenna (https://hackaday.com/2014/09/26/esp8266-distance-testing/), but one that has an external antenna for better range might be better for reliability.

Re: Exterior Gate Alarm, Horse Farm, Wireless

For this type of simple IoT application, I might be inclined to use something like an Expressif ESP8266 module at each gate (There are many types to choose from). They can be got pretty cheaply and would be easier to make low power for use with solar powered batteries. They can be programmed using M...

Nope. That's the limit of my knowledge I'm afraid.
Any joy with the quirks?
I think the 'u' parameter is to turn off UAS access, which may get it to work better for some unsupported drives.
Some drives are automatically blacklisted for UAS, so the 't' parameter marks them as ok to use UAS, AIUI.

Any SD card over 32GB formatted as FAT32 will typically be silently formatted as exFAT. This cannot be booted on the Pi. You will need special tools to force it to be formatted as FAT32 (search for Ridgecorp). Alternatively, use Balena Etcher or the new Raspberry Pi Imager to flash a plain Raspbian ...
