First, please DON'T use html in mails, which is addressed to mail
lists.
Now about your problem: you're doesn't setup ttyPSC0 as console device
for the kernel (as I understand, above is snapshot of terminal
output, am I right?).
Add string like this: console=ttyPSC0,115200n8 console=tty1 to the kernel parameters
(as simple hack you could add above string to rootfs enviroment
variable).

As example, here is part of our board config (not lite5200B):

baudrate=115200
preboot=echo;echo Type "run flash_nfs" to mount root filesystem over NFS;echo
netdev=eth0
addip=setenv bootargs $(bootargs)
ip=$(ipaddr):$(serverip):$(gatewayip):$(netmask):$(hostname):$(netdev):off panic=5
ethact=FEC ETHERNET
serverip=10.0.19.228
gatewayip=10.0.19.238
netmask=255.255.255.0
rootpath=/tftpboot/10.0.19.6
ipaddr=10.0.19.6
ntpserverip=10.0.19.238
ramargs=setenv bootargs root=/dev/ram rw
net_nfs=tftp 200000 $(bootfile);run setconsole nfsargs addip;bootm
setconsole=setenv bootargs $(console)
nfsargs=setenv bootargs $(bootargs) root=/dev/nfs rw nfsroot=$(serverip):$(rootpath)
kernel_addr=FE040000
flash_root=tftp 200000 $(bootfile);run setconsole jffs2rootfs addip;bootm
flash_self=run setconsole jffs2rootfs addip;bootm $(kernel_addr)
jffs2rootfs=setenv bootargs $(bootargs) rootfstype=jffs2 root=31:2 rw
bootfile=/tftpboot/uImage.vec5200
hostname=vec5200-3
bootdelay=1
console=console=ttyPSC0,115200n8 console=tty1
flash_nfs=run setconsole nfsargs addip;bootm $(kernel_addr)
tnote_cfg=setenv serverip 10.0.19.4;setenv gatewayip 10.0.19.4
net_nfs_tnote=run tnote_cfg;run net_nfs
bootcmd=run net_nfs
stdin=serial
stdout=serial
stderr=serial
