As a newbie to Debian on the Raspberry Pi, I tried booting the latest 
Debian arm64 netinst ISO without success. I used "dd" to copy the ISO 
image to a USB stick (nothing else on the stick), but when I tried to 
boot I get an error that the 2K block size is not supported by the RPi 
boot firmware and the boot fails.

Booting by USB is one of the available boot options.

Is there more preparation that needs to be done to the USB stick?
