3.2.1.3. Configuration-Specific Parameters

Table 9.  Device-Specific Parameters
Name Required Description
--activeparallel Optional Creates parallel flash contents compatible with active-parallel configuration mode. Only available on FPGAs which support active-parallel configuration.
--pfl Required if your FPGA configuration uses the PFL Specifies that the flash programmer use the parallel flash loader. Required if your FPGA configuration uses the parallel flash loader (PFL).
--optionbit=<optionbitaddr> 13 Required if your FPGA configuration uses the PFL Specifies the option bit address in your flash memory device. When you use this option, the sof2flash command generates both a .flash file and a .map.flash file. When you program the flash memory with the .map.flash file, it overwrites the default option bits. In almost all cases, the default option bits are appropriate and you should not program this file to flash.
13 Using the --pfl and --optionbits command-line options slows down sof2flash generation noticeably. For more information about when to use the --pfl and --optionbits command-line options, refer to AN386: Using the Parallel Flash Loader with the Intel® Quartus® Prime Software.
