[meta-xilinx] HDF and "no serial driver found"

I finally got a BOOT.Bin with the meta-xilinx fsbl and a custom bit
Whe the board starts, I have the following message

No serial driver found
resetting ...

(from minicom terminal (PC) on ttyUSB )

It seems the bitfile is downloaded because the green led 'DONE' of the
zybo is lighting.

The reason seems to be there is no 'stdout-path' in the automatically
generated dtb file from the HDF.

How to add the "stdout-path" item in the "chosen" section of the
generated dtb from the hdf file ?

I tried to add a uEnv.txt file but uboot-xlnx doesn't seem to read it

BTW i'm with 2016.4 and zybo board

PREFERRED_PROVIDER_u-boot = "u-boot-xlnx"
PREFERRED_PROVIDER_virtual/bootloader = "u-boot-xlnx"

Best regards
