Hardware Management Overview—MPCBL0010 SBC
Upon successful verification of the operational code checksum, the firmware jumps to
the operational code.
When the firmware enters firmware (FW) update mode, the operational code uses a
special branch, Software Interrupt, to jump to the FW update code in the boot block.
Once in FW update mode, the update code is copied into RAM, then the firmware jumps
to the code in RAM to execute. The firmware update code cannot execute out of flash
while the flash is being updated.
Figure 26 illustrates the firmware code process.
