Hardware and Software Constraints
SPI Flash Boot
TWI EEPROM Boot
Two kinds of SPI Flash are supported, SPI Serial Flash and SPI DataFlash.
The SPI Flash bootloader tries to boot on SPI0 Chip Select 0, first looking for SPI Serial flash,
and then for SPI DataFlash.
It uses only one valid code detection: analysis of ARM exception vectors.
The SPI Flash read is done thanks to a Continuous Read command from address 0x0. This
command is 0xE8 for DataFlash and 0x0B for Serial Flash devices.
The SPI Flash Boot program supports all Atmel DataFlash devices.
Table 11-2.
The SPI Flash Boot program supports all Serial Flash devices.
The TWI EEPROM Bootloader uses the TWI0. It uses only one valid code detection. It analyzes
the ARM exception vectors.
TWI EEPROM Boot supports all I
address 0x50.
The NVM drivers use several PIOs in peripheral mode to communicate with devices. Care must
be taken when these PIOs are used by the application. The devices connected could be unin-
tentionally driven at boot time, and electrical conflicts between output pins used by the NVM
drivers and the connected devices may occur.
To assure correct functionality, it is recommended to plug in critical devices to other pins not
used by NVM.
Table 11-3
are driven during the boot sequence for a period of less than 1 second if no correct boot program
is found.
