This section describes remote system configuration with the Stratix or
Stratix GX device and the Nios embedded processor, using a combination
of MAX
®
devices and flash memory.
You can use MAX 3000 or MAX 7000 devices and an industry-standard
flash memory device instead of enhanced configuration devices. In this
scheme, flash memory stores configuration data, and the MAX device
controls reading and writing to the flash memory, keeping track of
address locations.
The MAX device determines which address location and at what length
to store configuration data in flash memory. The Nios embedded
processor, running in the Stratix or Stratix GX device, receives the
