Hi all,

I am implementing uClinux using linuxppc-2.4 for the Xilinx Virtex-4 powerpc 
board.
http://www.itee.uq.edu.au/~jwilliams/mblaze-uclinux/powerpc_linux/

After I downloaded and booted up, it just stopped after "Mounting var: " 
message.

These are the MTD options that I've enabled:

# Memory Technology Devices (MTD)
CONFIG_MTD=y
CONFIG_MTD_PARTITIONS=y
CONFIG_MTD_CHAR=y
CONFIG_MTD_BLOCK=y
CONFIG_MTD_CFI=y
CONFIG_MTD_JEDECPROBE=y
CONFIG_MTD_GEN_PROBE=y
CONFIG_MTD_CFI_AMDSTD=y
CONFIG_MTD_RAM=y
CONFIG_MTD_UCLINUX=y

And I've enabled "/proc file system support", "ROM file system support", and 
"Second extended fs support"
for the File systems options.

Best Regards,
Jantira.
