AXIOM Beta/Firmware Flashing

16GB micro sd card required.

Download: https://github.com/apertus-open-source-cinema/axiom-firmware/releases

You need to first unpack the sd.dd.xz with the xz tool (or some other tool which can handle XZ data).

$ xz -k -d sd.dd.xz

Then you need to write the sd.dd image to the SD card, for example like this (this assumes that /dev/sdx is the device for the new SD card).

$ dd if=sd.dd of=/dev/sdx bs=128k status=progress

or using a GUI tool like https://www.balena.io/etcher/

Firmware Backup

The entire camera firmware is stored on a Micro SD card that's plugged into the Microzed. To back up the entire firmware we plug the Micro SD card into a Linux PC and do the following:

1. Find out which device the micro SD card is:

cat /proc/partitions

   mount

... should give you a list of all connected devices. Let's assume in our case that the card is /dev/sdc

2. Make sure the card is unmounted (all 3 partitions):

umount /dev/sdc1
umount /dev/sdc2
umount /dev/sdc3

3. Clone the entire card to a file:

ddrescue /dev/sdc sdimage.img sdimage.log
