The "gdb: no debug ports present" dmesg message means there is no serial ports configured for remote debugging. Edit '/boot/device.hints' and edit/insert: hint.uart.0.flags="0x80" or hint.sio.0.flags="0x80" For details please consult man uart(4) or man sio(4) depending on the serial driver is in use.
