Hi Andrei,

Firts aff all thank you very much for your help. I finally succed to
start the kernel. The problem was as SGDMA is activated then there is no
FIFO support on the TEMAC.

The kernel start properly now on NFS root file system but hangs with :
Unable to open initial console.

The root file system is just a copy of the MVISTA rootfs delivered with
ML403 eval kit.

A quick look in /dev show that there is no ttyS0 and that is why the
kernel did not succeed to open /dev/ttyS0.

My question is : 

1) Is their any config in the Kernel to select, in order to
have an auto initialisation of /dev (like withe CONFIG_DEVFS_FS in
previous verions)?

Or should I create ttyS0 node in the root file system?

2) Is there someone in the community that succeed to use TEMAC with
SGDMA? If yes could you tell me wich kernel version and what TEMAC patch
you are using.

One more time thanks to Andrei.

Kinds regards
