Quartus Prime Programmer - Where is the EPCS Flash Tool?

I've found a way to flash NOIS to our embedded target. Here's how I did it for anyone else running into this same issue.

The Short Version: Build project, convert resulting .elf to .hex. Then convert this .hex to .jic. Then use Quartus Programmer to flash .jic onto the board.

The Long Version:

1. Build your project (this creates a .elf as output)
2. Right click project in eclipse > Make Targets > Build > mem_init_generate
   1. mem_init_generate creates several .hex files. Each for a different target memory device. Select the one which matches your target memory device (e.g. mine was generic_quad_spi_controller2_0.hex)
3. Open Quartus Convert Programming File Tool
4. Set the following options:
   1. Programming File Type: .jic
   2. Configuration Device: <Select_Your_Target_Memory_Device)
   3. Mode: <Select_Your_Target_Mode>
   4. Click Flash Loader >> Add Device: <Select_Your_Target_Device)
   5. Click Add Hex Data: Add hex file created in step 2
5. Click Generate
6. Close Convert Programming File Tool
7. Open Quartus Prime Programmer
8. Add File > Select .jic created in step 5
9. Check 'Program / Configure' & 'Verify'
10. Click 'Start', NIOS code will be flashed to the target

Enjoy!
