We will be refreshing the eePROM on the raspberry pi 4 so follow this tutorial at your own risk!
In this video I show you how to set up your Raspberry Pi 4 to boot from USB using an SSD or other USB drive!
After you are all set up you do not need an SD Card in the Pi everything will run from the USB drive or SSD!
sudo apt update sudo apt upgrade sudo rpi-update sudo reboot sudo apt install rpi-eeprom sudo nano /etc/default/rpi-eeprom-update replace critical by beta crtl-x and Y sudo rpi-eeprom-update -d -f sudo rpi-eeprom-update -d -f /lib/firmware/raspberrypi/bootloader/beta/pieeprom-2020-05-15.bin you can check the bootloader version using: vcgencmd bootloader_version vcgencmd bootloader_config Check for BOOTORDER=0xF41. 4 is for booting from USB and 1 is booting from the sd card. copy all .elf and .dat files from our SD card into the boot directory of our new SSD
