Initial firmware

Upon delivery, the ctrlX CORE is provided with the operating system (Linux) including all system-rel-
evant apps and optionally selected apps. The operating system provides commissioning and mainte-
nance functions.
12.4

Booting

The ctrlX CORE control starts booting after switching on the 24 V voltage supply. Booting can be
monitored and checked using the status display.
The status display is red briefly after switching on the 24 V voltage supply. In the initialization phase,
the operating system (Linux) is started, the respective hardware drivers are loaded and the ctrlX CORE
application is then started. The status display of the control is flashing blue during that time. If the
initialization phase is completed, the control is in "Run" mode and the status display is permanently
green.

12.4.1 Secure Boot

Booting is secured by "Secure Boot". Thus, it can only be loaded by a runtime system released by Bosch
Rexroth. For the kernel development, this mechanism can be unlocked using an app and the respective
license.
If the system is unlocked, the status display of the control flashes yellow during each booting. The
warning "080E0305 Bootloader enabled!" is entered into the logbook.
To purchase the app and the license for unlocking purposes, please contact the Bosch Rexroth Service.
