Unibone disk image details

How to get details

XXDP images

To get the directory of xxdp images, use the tools from here: https://github.com/AK6DN/xxdpdir

You can mount the Unibone disk image (the sd card image) on your PC as follows. Unzip the image using

gzip -d sdcard_unibone_2023_02_14.dd.gz

Then use fdisk to find the start of the file system image:

jal@chatelet:~/t$ fdisk -lu sdcard_unibone_2023_02_14.dd 
Disk sdcard_unibone_2023_02_14.dd: 19.6 GiB, 21040988160 bytes, 41095680 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0xb72c8c81

Device                        Boot Start      End  Sectors  Size Id Type
sdcard_unibone_2023_02_14.dd1 *     8192 31115263 31107072 14.8G 83 Linux

This shows the partition start at 8192. Multiply by the sector size (512) to get the byte offset which is 4,194,304

Now mount the image as follows:

sudo mount -o loop,offset=4194304 /path/to/sdcard_unibone_2023_02_14.dd /media/$USER/test

(you might want to make that test directory before mounting).

With this image mounted you can get a directory of a XXDP disk image like this:

./xxdpdir.pl --image=/home/jal/test/10.03_app_demo/5_applications/xxdp.rl02/xxdp25.rl02 --directory

xxdp25.rl02
