CONTINUE IF YOU WANT TO CONFIGURE M5 TO BOOT DEBIAN FROM EMMC

If you proceed, you will no longer be able to boot from the SD card until you reformat EMMC**

Login for Debian was ‘pi’ with password ‘bananapi”
or
Login for Debian was ‘root’ with password ‘1234”

At the terminal prompt $, ran these two commands:

sudo apt-get install pv
curl -sL https://github.com/BPI-SINOVOIP/bpi-tools/raw/master/bpi-tools | sudo -E bash

Insert the USB thumb drive into Bpi M5 and mount in via terminal $ using these commands:

sudo fdisk -l

Used to see what the OS is naming your USB drive
Mine was /dev/sda1

sudo mkdir /media/usb

Used to make a directory (mount point) for mounting the USB drive. This directory may already exist.

sudo mount /dev/sda1 /media/usb
cd /media/usb

Used to mount the USB drive to the /media/usb folder

ls

Lists the contents of the USB drive.
Should see your .zip .xz version of the Debian image file

sudo bpi-copy Armbian_24.5.1_Bananapim5_bookworm_current_6.6.31_xfce_desktop.img.xz /dev/mmcblk0

Copies, unzips, and installs the image file onto the EMMC
I got an error at this point related to “unzip” not being a valid command
I just ran the command: "sudo apt-get install unzip or lzma xz"
Re-ran the command: "sudo bpi-copy"… listed above

The boot order for the Bpi M5 is Start ROM:Boot EMMC and then Boot SD Card, 
so if you want to go back to booting from the SD Card after installing an OS 
on the EMMC, you will have to erase it first and start over.

To erase the EMMC for SD Card bootup:

    Connect the M5 to your computer via USB debug console cable

    Use the Amlogic USB Burning Tool to format the EMMC
