buildroot rootfs just hangs

Hi all,
I'm trying to install a rootfs on a usbpen for an embedded board. The board has (I think) redboot which sets linux up to the loading of the file system. I was given a usbpen with an example fs which works fine. Via rs-232 I can log in, run programmes etc. However I was told to load more software packages I should use buildroot to add packages and updates. Unfortunately no other advise was give. So I though I'd try to build my own, basic system at first. So I selected ARM and 920T as the processor and selected tar the root file system to produce a image for the usbpen, then set it away to compile. I unzipped the image to my pen and started the system. Via USB I saw it load the bootloader then report on my root
scsi 0:0:0:0 Direct-Access Intergral Courier PMAP PQ : 0 ANSI : 0 CSS

sd 0:0:0:0: attached scsi removeable disk sda
EXT-fs warning mounting unchecked fs, running e2fsck is recommend
VFS: Mounted root (ext2 filesyfs),

So it seems to mount my rootfs? However I can't login or open folders etc via the rs232 connection. Is there something I need to do in buildroot so it knows to use the comms port to speak to the host? Thanks

Hard to know what is in your root filesystem, especially including the init script. Perhaps adding an argument to the kernel like 'console=/dev/ttyS0' would do what you want. See the Linux Serial Console HOWTO for more detailed information.
