I've found an answer by myself.

nios2-debug loads binary image through nios2-gdb-server, but

debugger on IDE loads image by nios2-download.

It failed when I invoked nios2-elf-gdb from Emacs

because I wrote .gdbinit by copying from nios2-debug like below:

file test.elf

target remote localhost:2342

load test.elf

break main

jump _start

When I load by nios2-download (without -g option) and I remove "load test.elf" from .gdbinit, it succeeded to debug from nios2-elf-gdb on Emacs.

Thanks.
