wraps around the top of the memory and fills up the bottom boot area.
The wrap around does not occur if the bottom boot area is used for
processor/user HEX data file storage.
The block addressing mode allows better control of flash memory
allocation. You can allocate a specific flash memory region for each
application configuration page. This allocation is done by specifying a
block starting and block ending address. While selecting the size of the
region, you should account for growth in compressed configuration
bitstream sizes due to design changes and additions. In local update
mode, all configuration data is top justified within this allotted memory.
In other words, the last byte of configuration data is stored such that it
coincides with the highest byte address location within the allotted space.
Lower unused memory address locations within the allotted region are
filled with 1's. These filler bits are transmitted during a configuration
cycle using page 1, but are ignored by the Stratix device. The memory
map output file provides the exact byte address where real configuration
data for page 1 begins. Note that any partial update of page 1 should erase
all allotted flash sectors before storing new configuration data.
In the block addressing mode, HEX input files can be optionally added to
the bottom boot and main flash data areas (one HEX file per area is
allowed). The HEX file can be stored with relative addressing or absolute
addressing. For more information on relative and absolute addressing,
see the Using Altera Enhanced Configuration Devices chapter of the
Configuration Handbook.
