SAM-BA Monitor
SAM9G35
SAM9G35
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:
Once the communication interface is identified, the application runs in an infinite loop waiting for
different commands as listed in
NVM Bootloader

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
