Chapter 8. Rewriting Image Files
This chapter explains the procedure for rewriting the image file written to Armadillo-IoT G3's internal storage (eMMC
and QSPI flash memory).
The bootloader image files used in this chapter are included on the development set DVD. The latest versions of the
files can be downloaded from the "Armadillo site". As over time new functionality is added and defects are fixed, we
recommend checking if versions newer than that on the DVD have been released or not and then using the latest version.

8.1. Using the Installation Disc
Using the installation disc, all of the images on the internal storage can be rewritten at once. They can be used as a recovery
method if Armadillo stops booting due to a software issue.
As all image files saved in the internal storage are overwritten, any data or appli-
cations already saved there will be deleted.
The installation disk is created with ATDE. The file used to create the installation disk is shown below.
