State saving and loading¶
Renode allows you to save the state of the emulation to a file.
Such a file can be transferred to another user and then loaded to fully recreate the original setup. No additional binaries or configuration files are required.
To save the emulation state to a file called statefile.dat, run:
(monitor) Save @statefile.dat
This file can be used with the Load command:
(monitor) Load @statefile.dat
It is important to remember that a state file created on one version of Renode may not be compatible with another one.
Please note that loading the state file clears the current emulation, and is equivalent to:
(monitor) Clear
(monitor) Load @statefile.dat
Note
After the state is loaded, you must manually set the Monitor’s context and reopen the UART windows:
(monitor) mach set 0
(machine-0) showAnalyzer sysbus.uart
State saving in tests¶
It’s possible to use the state saving and loading mechanism when defining complex Robot tests. For details see the Test cases dependencies section.
