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 2.6.17.1 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.
