12.1.4.1 Default Boot Sequence

When no Boot Configuration Packet is available in the OTP User area, the ROM code uses a default boot configuration and tries to boot from the following external memories:

SD Card/e.MMC (SDMMC 0) - PA0 to PA5
SD Card/e.MMC (SDMMC 1) - PA6 to PA11
QSPI NOR Flash (QSPI) - PB15 to PB26
NAND Flash (SMC) - PD0 to PD14
SPI (FLEXCOM 5) - PA14 to PA17

See Table 12-15 for further details.

If no bootable file is found in any of these memories, the ROM code runs the SAM-BA Monitor.
