Simplest method to transmit a file to FPGA

Provided that one has a file that is to be transmitted down to the FPGA and it will store every byte into internal or external memory (maximum size is around 1MegaByte). What is the preferred way of ...

You can use system console for this with a JTAG to avalon master: https://www.altera.com/en_us/pdfs/literature/hb/qts/qts_qii53028.pdf

There are APIs called "master_read_to_file" and "master_write_from_file" that you can use to push a file down to memory in the FPGA and vice versa for the opposite direction. I also used to use Nios II for this sort of thing with something called host FS where I could have Nios open a file up on the host for read/write purposes over the JTAG channel but I have no clue if that's still supported. I suspect system console can move the data faster than host FS since I seem to recall host FS was only around 4kB/s back with the first generation USB blaster.
