debian arm64 linux for the odroid m1

debian bookworm setup

1. download image:

wget https://github.com/inindev/odroid-m1/releases/download/v12.0-rc2/odroidm1_12.0-rc2.img.xz

2. determine the location of the target micro sd card:

before plugging-in device:

ls -l /dev/sd*
ls: cannot access '/dev/sd*': No such file or directory

after plugging-in device:

ls -l /dev/sd*
brw-rw---- 1 root disk 8, 0 Jul 20 18:44 /dev/sda

note: for mac, the device is /dev/rdiskX

3. in the case above, substitute 'a' for 'X' in the command below (for /dev/sda):

sudo sh -c 'xzcat odroidm1_12.0-rc2.img.xz > /dev/sdX && sync'

when the micro sd has finished imaging, eject and use it to boot the odroid m1 to finish setup

4. login:

user: debian@192.168.1.xxx
pass: debian

5. take updates:

sudo apt update
sudo apt upgrade

6. create account & login as new user:

sudo adduser youruserid
echo '<youruserid> ALL=(ALL) NOPASSWD: ALL' | sudo tee /etc/sudoers.d/<youruserid>
sudo chmod 440 /etc/sudoers.d/<youruserid>

7. lockout and/or delete debian account:

sudo passwd -l debian
sudo chsh -s /usr/sbin/nologin debian

sudo deluser --remove-home debian
sudo rm /etc/sudoers.d/debian

8. change hostname (optional):

sudo nano /etc/hostname
sudo nano /etc/hosts

building debian bookworm arm64 for the odroid m1 from scratch

The build script builds native arm64 binaries and thus needs to be run from an arm64 device such as a raspberry pi4 running a 64 bit arm linux. The initial build of this project used a debian arm64 raspberry pi4, but now uses a odroid m1 running pure debian bookworm arm64.

1. clone the repo:

git clone https://github.com/inindev/odroid-m1.git
cd odroid-m1

2. run the debian build script

cd debian
sudo sh make_debian_img.sh

note: edit the build script to change various options: nano make_debian_img.sh

3. the output if the build completes successfully

mmc_2g.img.xz

installing on m.2 ssd /dev/nvme0n1 media

1. copy the image file on to the ssd media (root user required)

xzcat odroidm1_12.0-rc2.img.xz > /dev/nvme0n1

2. remove mmc media and boot from petitboot

determining partition uuid

the partition uuid is required for the boot script /boot/boot.txt

fdisk /dev/nvme0n1

select command i

Selected partition 1
         Device: /dev/nvme0n1p1
          Start: 32768
            End: 976773119
        Sectors: 976740352
           Size: 465.7G
           Type: Linux filesystem
      Type-UUID: 0FC63DAF-8483-4772-8E79-3D69D8477DE4

           Name: rootfs

select command q to exit

place the uuid in the /boot/boot.txt build script and regenerate

setenv bootargs console=ttyS2,1500000 root=PARTUUID=48432519-7258-4785-977e-3b1d26d88169 rw rootwait...
