Hello everyone, I do not know how to properly run insight for eCos application. Would you please teach me ? I started to run insight like next on cygwin prompt. LINK@ariga ~/ether_test_plus_simplemain-O1 $ sh-elf-insight.exe nc_test_slave.o Then insight's source window appeared showing nc_test_slave.c. In order to break at sure point,I set breakpoint at top of cyg_start function. Red square mark was shown. Then I clicked Running-Man icon,and DownLoading began and next log appeared in console window. 0x8000acb2 in ?? () Loading section .text.cyg_start, size 0x2a0 lma 0x0 Loading section .text.pexit, size 0x38 lma 0x0 Loading section .rodata, size 0x3b0 lma 0x0 Loading section .text.do_udp_test, size 0x65c lma 0x0 Loading section .text.do_read, size 0xe0 lma 0x0 Loading section .data.slave_tcp_port.3876, size 0x4 lma 0x0 Loading section .text.do_tcp_test, size 0x620 lma 0x0 Loading section .text.nc_slave, size 0x4f8 lma 0x0 Loading section .text.net_test, size 0x68 lma 0x0 Loading section .text.simple_program, size 0xdc lma 0x0 Loading section .text.calibrate_load, size 0x50c lma 0x0 Loading section .text.start_load, size 0x104 lma 0x0 Loading section .text.net_load, size 0x9c lma 0x0 Loading section .text.do_some_random_computation, size 0x78 lma 0x0 Loading section .text.net_idle, size 0x4c lma 0x0 Loading section .text.test_delay, size 0x38 lma 0x0 Start address 0x0, load size 8652 Transfer rate: 3 KB/sec, 298 bytes/write. (gdb) When Download finished,"Make breakpoint pending on future shared library load?" window poped up (why). I clicked "NO",then transfered to running state,Running-Man icon changing to STOP icon, and down in Source Window "Program is running" appeared. But never breaked at breakpoint I would like to stop. I wonder where I was wrong? I also tried to GDB remote debugging. Although it became nearly the same result,I appended log below. -- this is GDB remote debugging log LINK@ariga ~/ether_test_plus_simplemain-O1 $ sh-elf-gdb nc_test_slave.o GNU gdb 6.7.1 Copyright (C) 2007 Free Software Foundation, Inc.

I append test-9.txt logfile compressed in gzip file. Especially I have next suspicious points. 1.Am I correct using nc_test_slave.o in starting dubugger ? 2.There is other way to run program, so surely break at cyg_start(). Please help me. Thank you in advance. Masahiro Ariga
