When I tried debugging a mips64/Linux target with i686/Linux host, I
got the following results:
[gdbserver side]
$> ./gdbserver 200.121.3.185:6001 matrix_rev
Listening on port 6001
Remote debugging from host 200.121.3.185
readchar: Got EOF
Remote side has terminated connection. GDBserver will reopen the connection.
[gdb side]
$> ./gdb matrix_rev

This GDB was configured as "--host=i686-pc-linux-gnu --target=mips64el-linux"...
(gdb) target remote 200.121.3.191:6001
Remote debugging using 200.121.3.191:6001
Couldn't establish connection to remote target

gdbserver was configured for mips64el-linux. gdbserver and the debugged program were both compiled with cross gcc 3.3 (mips64el-linux-gcc -mabi=64 -static) on i686/Linux host.
"file matrix_rev" gives the following information: ELF 64-bit LSB MIPS-III executable, MIPS, version 1 (SYSV), for GNU/Linux 2.4.0, statically linked, not stripped.
Could you give more advice ?
Thanks.
