There is no message on ttyS1.
I changed "console=ttyS1,1152000" to "console=ttyLv0" and enable
serial console support on L4Linux configration.
The result is the following (when using DOpE).

Without DOpE, the messages of "l4dope" (last 32 lines) don't exist and
others are the same.
I'm not able to find any problems in these messages...
It seems there is no too serious message in this Log.
Could I request your opinion again ?
