4 Boot Sequence Solution

As Section 2.2 shows, depending on system BOM, different peripheral devices and boot modes may be required, which leads to different boot flow and boot time. Software is needed to take care boot flow depending on the specific hardware design. This section introduces two typical boot sequence solutions for reference.
