column. This is the default setting in the device.
Perform the following steps:

file in the text editor and add the following line:
autoUpdate=<Image_file_name>.bin

During the booting process, the device checks automatically the following criteria:
– Is an external memory connected?
– Is a
startup.txt
file in the main directory of the external memory?
– Does the image file exist which is specified in the
startup.txt
file?
– Is the software version of the image file more recent than the software currently running in
the device?
When the criteria are fulfilled, the device starts the update procedure.
