SAM-BA Monitor
SAM9G45
Before performing the jump to the application in internal SRAM, all the PIOs and peripherals
used in the boot program are set to their reset state.
Table 11-3.
If no valid code has been found in NVM during the NVM bootloader sequence, the SAM-BA
Monitor program is launched.
The SAM-BA Monitor principle is to:
NVM Bootloader
NAND
SD Card
SPI Flash
TWI0 EEPROM
SAM-BA Monitor
– Initialize DBGU and USB
– Check if USB Device enumeration has occurred.
– Check if characters have been received on the DBGU.
– Once the communication interface is identified, the application runs in an infinite
loop waiting for different commands as listed in
