Preparing the SD card
The DExx requires operating software/firmware to be installed on an SD card. This SD card needs
to be prepared with a bootloader the first time you use it. Start by downloading the latest version of
the bootloader and firmware from the link here:-
To prepare the SD card we recommend the program “Balena Etcher” which is available here:-
.
This program is available for Windows, Linux and MacOS. The instructions that follow are for
Windows operating systems specifically, but the process should be very similar for Linux and
MacOS too.
Download and install the Balena Etcher software and run it, you should see a window like the one
shown below.
Click on “Flash from file”. A standard file requester window should appear. Navigate to your
download folder and choose the SD card image file. It should be named “sdcard_cv.img” or
“sdcard_cv”.
