1. There is a hidden onchip_mem inside the epcs controller. The onchip_mem content initialized in sof will be your reset vector as you defined to reset from epcs controller in sopc builder. Please check the boot loader sources at

/opt/altera9.0/nios2eds/components/altera_nios2/boot_loader_sources

2. nios2-terminal has nothing to do with booting.

3. You can still use jtag uart with "Bypass output when no connection" in uart config. Or you can use serial uart, ie RS232C.
