Build by parts

Build bootloader

$ cd 
$ sudo  -c bootloader

Build rootfs

Internet connection should be available

$ cd 
$ sudo  -c rootfs

Pack rootfs

To create the root file system archive (rootfs.tar.gz) and UBI image (rootfs.ubi.img), run the following commands:

$ cd 
$ sudo  -c rtar
$ sudo  -c rubi

Create boot SD card

1. Follow the above steps for make rootfs, kernel, bootloader;
2. Insert the SD card to card reader connected to a host system;
3. Run the following commands (Caution! All data on the card will be destroyed):

$ cd 
$ sudo  -c sdcard -d /dev/sdX

where '/dev/sdX' path to the block SD device in your system.

Create a boot SD card image using a loop device

It is also possible to use the "" script to create a boot SD card image, while using a loop device instead of attaching a real SD card.

Create an empty file using the following command:

$ dd if=/dev/zero of=-debian-sd.img bs=1M count=3720

The above command creates a 3700MiB file representing the SD card.

Attach the first available loop device to this file:

$ sudo losetup -Pf -debian-sd.img

To find the actual loop device being used, run:

$ losetup -a
