This leads to three different boot flows and that are shown in the following pictures.
*'''NAND-NOR option: ''' This configuration makes use of NAND flash as primary internal boot device. NOR flash is used as secondary boot device where, for example, a so-called ''golden image'' of the bootlader can be stored.

*'''NAND-only option: ''' This configuration makes use of NAND flash as primary - and only - internal boot device. [[File:AXELULite-boot-NAND.png|thumb|center|750px|Boot flow for ordering code in the form TBD]] 
'''NOR-NAND option'''
 
This configuration makes use of NOR flash as primary internal boot device. Nevertheless, NAND flash is available for generic storage. NAND flash can not be used as booting device.

*NOR-NAND option: This configuration makes use of NOR flash as primary internal boot device. Nevertheless, NAND flash is available for generic storage. NAND flash can not be used as booting device.
*NOR option: From the point of view of boot process, this configuration is identical to the NOR-NAND option. This is clearly cheaper because NAND flash is not populated.
