Memory information

CLI mode

In the CLI (in any mode), you can see the memory banks via the show memory command:

hdt> show memory                                                                
Memory Banks                                                                    
 bank 00      : 128 MB RAM@                                                     
hdt>

To have more information, enter the MEMORY mode via the memory command:

hdt> memory                                                                     
memory>

To inspect memory banks, use the show bank <number> command:

memory> show bank 0
