NIOS only boots after nios2-terminal connects

I generate a .jic file and download it into the EPCS64 device.

However once the FPGA starts up, the NIOS does not boot.

Only when I start the nios2-terminal on the PC does the NIOS boot.

Any ideas why the NIOS does not boot by itself?

Thank you very much,

Jan.

    Hi Kelly,

    In our case the solution was to remove the JTAG Debug UART and move the stdout/stdin/stderr to a standard UART.

    The NIOS now boots from startup without waiting for the nios-terminal to connect.

    Thank you,

    Jan.

    Hi Jan,

    The nios2-terminal command allows you to monitor stdout, stderr or both and to provide input to a NIOS II processor subsystem through stdin.


    The EPCS is not directly addressable. You will need to get a small boot loader program and load it into an embedded memory and set the embedded memory as the reset vector.


    Here is also a link to check out on booting methods of the NIOS II processor.
