The BootROM has a search limit to locate the device image boot header for every boot mode. See Table 1 for boot image search limits for each mode.
Note: For smaller devices, the
BootROM wraps around to zero and continues again till it reaches the stated search
offset size.
Note: When using OSPI
or QSPI dual-stacked mode, the BootROM can only access the lower QSPI or OSPI
addressable flash memory space for boot. After boot, the PLM can access the upper QSPI
or OSPI for additional image storage.
