Raspberry Pi - bitcoinfacts/GlacierProtocol Wiki

It's possible to use the Raspberry Pi Model 3B as one of the Setup computers. For that, one of the SETUP BOOT USBs should be flashed with Raspberry Pi OS. Then, follow these steps to make the Pi bootable from USB:

  1. Boot normally from SD card
  2. In the terminal, run:
echo program_usb_boot_mode=1 | sudo tee -a /boot/config.txt
  1. Reboot from SD card.
  2. To verify that USB boot was enabled, run:
vcgencmd otp_dump | grep 17:

Check that the output 17:3020000a is shown. If it is not, then the OTP bit has not been successfully programmed.
