[Hackable:1] trouble booting

[Greg Bonett]

Hi,
I'm having some trouble booting hackable:1.  I downloaded the tar balls
and extracted them to fat and ext2 partitions on a 2GB micro sd card.  I
then tried to boot using the NOR uboot.  It gets stuck after the
message: " s3c2410_udc: debugfs dir creation failed -19"
has anyone else had this problem?
is there an easy way to check if I properly extracted to tar balls to my
SD card?
Thanks.
