[U-Boot-Users] FDT: missing stdout-path

[Bill Cook]

Hello experts,

With U-Boot-1.3.2 and a Freescale MPC8313ERDB,
I'm getting this message from bootm

...
   Booting using the fdt at 0xfc700000
   Loading Ramdisk to 07ca1000, end 07f419bf ... OK
   Loading Device Tree to 007fc000, end 007fefff ... OK
   WARNING: could not set linux,stdout-path FDT_ERR_NOTFOUND.
   ERROR: /chosen node create failed - must RESET the board to recover.
   Resetting the board.

   U-Boot 1.3.2 (Apr  2 2008 - 10:02:55) MPC83XX

   Reset Status: Software Hard, External/Internal Soft, External/Internal
Hard

   CPU:   e300c3, MPC8313E, Rev: 10 at 333.333 MHz, CSB:  166 MHz
...

What do I need to add to DTS file or u-boot environment to make this go?


Thanks

Bill Cook

You probably need serial0, serial1, etc. aliases.  See the device trees
in head-of-tree Linux.

...and that error message could stand improvement to give the poor user 
a better clue that he is missing the /aliases node or /aliases/serial0 
property.

The current error message reminds me of the "Fog in Seattle" joke
