3.1.4. RBF Configuration File Format
If you do not use the Parallel Flash Loader II Intel FPGA IP core to program the flash, you must generate the .rbf file.
The data in .rbf file are in little-endian format
Table 10. 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 11. Writing 16-bit Data
For 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
LSB: BYTE0 = 02 MSB: BYTE1 = 1B LSB: BYTE2 = EE MSB: BYTE3 = 01
D[7:0] D[15:8] D[7:0] D[15:8]
0000 0010 0001 1011 1110 1110 0000 0001
