Hi,
I have compiled linux kernel with arm-eabi toolchain on Ubuntu. The kernel is working. Now I'd like to debug it with gdb. I tried this command: arm-eabi-gdb vmlinux
My questions: Which gdb should I use? There is a gdb in the arm-eabi (downloaded with android) toolchain. This will good? I have tried that but I have got Don't know how to run. Try "help target" error message. I tried to set breakpoint to __init_begin, this works but when I tried to start the debug with *start, run, cont* I have got this error message. attila@attila-desktop:~/Upload$ arm-eabi-gdb vmlinux GNU gdb (GDB) 7.1-android-gg2 This GDB was configured as "--host=x86_64-linux-gnu --target=arm-elf-linux". Reading symbols from /home/attila/Upload/vmlinux...(no debugging symbols found)...done. (gdb) break __init_begin Breakpoint 1 at 0xc0008000 (gdb) load vmlinux You can't do that when your target is `exec' (gdb) start Function "main" not defined. Make breakpoint pending on future shared library load? (y or [n]) n Starting program: /home/attila/Upload/vmlinux Don't know how to run. Try "help target". (gdb) cont The program is not being run. (gdb) run Starting program: /home/attila/Upload/vmlinux Don't know how to run. Try "help target".
