9.3. Bootloader Commands
The bootloader CLI provides a bunch of powerful commands to control the board, which basically can be grouped
into
 Information Commands
 Memory Commands
 Flash Memory Commands
 Execution Control Commands
 Download Commands
 Environment Control Commands
 Flattened Device Tree Support Commands
 Storage Device Control Commands
 File System Support Commands
 Kontron Command Extensions
Typing “help” at the bootloader command line prompt will show up a list of the commands
available. Typing “help <command>” will show specific command help. Further help can be
found under https://www.denx.de/wiki/view/DULG/UBoot
On the SMARC_sAL28 bootloader, the powerful hush shell is enabled, which is similar to Bourne shell and provides
features similar to a linux shell:
 Control structures (if … then … else … fi etc.)
 Command line completion
 Command line editing
 Command line history up to 20 entries
 Local environment variables
