Re: RPi 4 : Lost GPIO-3 restart (and fix)

Unless we find any serious problems in the next few days the next version of the bootloader will default to WAKE_ON_GPIO=1. The main reason is that it's not possible to turn of 5V because the the board can be powered via the 5V pin and some HATS don't like having 5V but no 3V3. The halt power off c...

Running image-backup with no parameters will create a full backup. To create...

That message is normal and should be ignored. Simply reboot and the filesystem will be expanded (be patient as the expansion process involves an extra reboot that is automatically initiated).

Re: Running Raspbian on USB Devices : Made Easy

I suspect the problem is your system is trying to auto-mount the device as soon as you plug it and and exfat isn't supported. The device doesn't need to be (and shouldn't be) mounted prior to running usb-boot. usb-boot will present you with a list of /dev/sdX devices it finds and ask you to select t...

The USB device need not be formatted. The usb-boot script will partition and format the USB device for you.
