I have an sof and jic file for a CycloneV device with an MX25L12833FM2I SPI-flash.
I need to program the SPI-flash with an external burner (programmer) from HiLo systems.
What is the file I need ...
To find out what's wrong with your programming method, I'd read back a flash programmed by JTAG indirect programming method with the external programmer. Possible issues are e.g. reversed bit order.
