3.1.4. RBF Configuration File Format

If you do not use the Parallel Flash Loader II Intel® FPGA IP to program the flash, you must generate the .rbf file.

The data in .rbf file are in little-endian format.

Table 19.  Writing 32-bit Data For a x32 data bus, the first byte in the file is the least significant byte of the configuration double word, and the fourth byte is the most significant byte.
Double Word = 01EE1B02
LSB: BYTE0 = 02 BYTE1 = 1B BYTE2 = EE MSB: BYTE3 = 01
D[7:0] D[15:8] D[23:16] D[31:24]
0000 0010 0001 1011 1110 1110 0000 0001
Table 20.  Writing 16-bit DataFor a x16 data bus, the first byte in the file is the least significant byte of the configuration word, and the second byte is the most significant byte of the configuration word.
WORD0 = 1B02

WORD1 = 01EE
