Hi all:
My gdb is configured as "--host=i686-pc-linux-gnu --target=arm-elf"
and remote debugging with an arm simulator which be a target.
but something is strange after the connection created. I set a
breakpoint in the main function (br main), but after the connection
created the gdb stop at the first instruction of crt0.S.
(gdb) target remote 140.123.103.7:23137
Remote debugging using 140.123.103.7:23137
start () at ../../../../../../gcc-3.4.1/newlib/libc/sys/arm/crt0.S:36
36 mov r0, #AngelSWI_Reason_HeapInfo
Current language: auto; currently asm
(gdb)
Maybe my gdb stub doesn't handle the packet well.
Following is the command form gdb and the correspond reply by my gdb stub.
waiting for GDB connection establish...
