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.
