Thanks for your feedback.

Unfortunately, what you suggest is not what I am trying to achieve.

I want to run a JTAG session and NOT program an external flash such as the ECPS.(unless I mis-understand some feature of the nios-flash programmer)

I can upload the sof over JTAG using the quartus_pgm.exe so the firmware is no problem.

My problem is directly programming the SDRAM(it could also be onchip memory for other projects) over JTAG and then executing the code.

I would then want to run a nios2-terminal to get messaging over the JTAG-UART.

I appreciate this configuration is then lost after a power cycle and will revert to the production image in the EPCS device. (which is exactly what i want)
