3.1.1 How do you create a service system for the NCU?
Purpose
In case service is needed, create a portable "Emergency Boot System" (EBS) on a USB
memory. Thus you can start the booting of the NCU from the service system in order to carry
out various service tasks, such as data backup or updates, in a service shell.
Two partitions are created on the service system:
● A Linux partition that is not displayed under Windows.
● An FAT partition, to backup files or save software updates.
The FAT partition can be read and written to under Linux as well as from a Windows system.
The FAT partition can be addressed under the path/data in a command shell under Linux.
