12.1.4.1 Default Boot Sequence (Without Boot Configuration Packet)

When no Boot Configuration Packet is available in the OTP area, the ROM code uses an internal default Boot Configuration Packet to configure the DBGU as a console and tries to boot from one of the following memories:

• SDMMC0 (PA15, PA16, PA17, PA18, PA19, PA20)
• SDMMC1 (PA2, PA3, PA4, PA11, PA12, PA13)
• QSPI0 (PB19, PB20, PB21, PB22, PB23, PB24)
• FLEXCOM0 - SPI (PA0, PA1, PA3, PA4)
• NAND Flash (PD0 to PD13)

See Table 12-5 for further details.

If no bootable file is found in these memories, the ROM code goes to the SAM-BA Monitor.
