Turris Omnia has two serial ports. Both are already specified in device tree file. But U-Boot by default does not allow to use more than one serial port unless CONFIG_SERIAL_PROBE_ALL is not enabled. After enabling CONFIG_SERIAL_PROBE_ALL, U-Boot see also second serial port (but is inactive by default): => coninfo List of available devices: serial@12000 00000007 IO stdin stdout stderr serial@12100 00000007 IO To allow simultaneously to use more input / output devices it is needed to enable CONFIG_CONSOLE_MUX option. With CONFIG_CONSOLE_MUX it is possible to call: => setenv stdout 'serial@12000,serial@12100' And U-Boot output is then visible on both serial ports.
