Could it be a problem in my bootargs command line ?
I mean, maybe the console=3DttyS0,11500 wrong ?
Because my "Run" LED is on...

I tried ttyS0, ttyCPM0, tty0.
It should be ttyCPM0, or just leave it out and make sure that
/chosen/linux,stdout-path is set properly.

Have you tried enabling early CPM debugging output?

Well, I have to say, yes, I tried:
CONFIG_PPC_EARLY_DEBUG_CPM=3Dy
CONFIG_PPC_EARLY_DEBUG_CPM_ADDR=3D0xf0001ff8

I have also tried without specifying the console outp=FBt:
setenv bootargs root=3D/dev/ram rw

Nothing more...
