Boot flows: SPL vs SBL#
There are 2 main kinds of boot flow supported on this processor: SPL boot, and SBL boot.
In general, the Linux SDK was developed and tested with SPL boot. SPL boot is the default boot mode for the Linux SDK filesystem images. For more information about the SPL boot flow, reference the Linux SDK docs, section Boot flow.
The MCU+ SDK was mostly developed and tested with SBL boot. For more information about the SBL boot flow, reference the MCU+ SDK docs, section Secondary Bootloader (SBL).
Note
SBL that does not include Linux in the title will NOT load Linux onto the A53 cores.
