[ELDK] No serial output after arch: exit

[Chris Alfred]

I am trying the latest git kernel on a lite5200.

To compile I used:
    make CROSS_COMPILE=ppc_82xx ARCH=ppc lite5200_defconfig
    make CROSS_COMPILE=ppc_82xx ARCH=ppc uImage

My uBoot arguments are:

---------------------
baudrate=115200
preboot=echo;echo Type "run flash_nfs" to mount root filesystem over 
NFS;echo
netdev=eth0
ramargs=setenv bootargs root=/dev/ram rw
addip=setenv bootargs ${bootargs} 
ip=${ipaddr}:${serverip}:${gatewayip}:${netmask}:${hostname}:${netdev}:off 
panic=1
flash_nfs=run nfsargs addip;bootm ${kernel_addr}
flash_self=run ramargs addip;bootm ${kernel_addr} ${ramdisk_addr}
rootpath=/opt/eldk/ppc_82xx
ethact=FEC ETHERNET
netmask=255.255.255.0
ethaddr=00:01:AF:52:01:01
ipaddr=192.168.1.8
gatewayip=192.168.1.100
serverip=192.168.1.103
hostname=lite
bootcmd=run net_nfs
bootdelay=2
net_nfs=tftp ${loadaddr};run nfsargs addip;bootm
autoload=no
jffs2args=setenv bootargs root=/dev/mtdblock0 rw rootfstype=jffs2
flash_jffs2=run jffs2args;bootm
bootfile=MPC5200/uImage
loadaddr=200000
nfsargs=setenv bootargs ${console} root=/dev/nfs rw 
nfsroot=${serverip}:${rootpath}
console=console=ttyPSC0,115200
stdin=serial
stdout=serial
stderr=serial
-----------------

The serial output after reset (bootcmd = run net_nfs) is:

-----------------

Then after about 3 seconds, the board reboots.

Thanks for any help,
