A Raw Binary File contains the binary equivalent of a Tabular Text File (.ttf). rbf) containing configuration data for use outside the Quartus II software.
You will now have your RBF file, as required. Altera Corporation is a Silicon Valley manufacturer of PLDs, reconfigurable complex digital circuits. Nios2-elf-objcopy -I srec -O binary "./your_file.flash" "./your_file.rbf" This converts the SOF file into a FLASH file, which is an ASCII representation of the desired RBF. Sof2flash -offset=0 -input="./your_file.sof" -output="./your_file.flash" Note that although you need Quartus installed in order to do this, you don't need to pay for a subscription, because the NIOS II Command Shell works even if Quartus doesn't have a valid licence.Ĭd to the directory containing your SOF then type: This can be done using Altera's "NIOS II Command Shell", which can be run from the Quartus folder in the Start menu. It contains the data required to initialise the FPGA directly.Īlthough you can output an RBF from Quartus ( File -> Convert Programming Files.), I suspect from your question that you're looking for a way to directly convert a SOF to an RBF. It represents the raw data that will, for example, be loaded into a flash memory for initialising an FPGA on power-up.Ī SOF is an " SRAM Object File".
