When I try to run sof2flash utility (ADS 18.1 Standard or Pro) with .sof of 10CL016YU256C8 device based project I get an error message: "foo:10A10CL016YU256C8G31/10/2019 14:50:25 - (SEVERE) sof2flash: Unrecognized device family in SOF." So I can't create xxx_hw.flashfile.
Why? How to fix that?
For current design, we recommend to use Quartus Prime Programming as programming method instead of NIOS II Flash Programming(sof2flash, elf2flash).
Quartus Prime Programming flow is used for combining a *.sof and a *.hex file into a single *.pof or *.jic file for programming into the configuration or booting device.
