Looks like you're trying to use DEV_FS and it can't mount itself. Since you're using a romfs partition, my first guess is that the /dev directory doesn't exist and the DEV_FS subsystem can't create it. So try adding /dev to your fs, re-build, re-upload the filesystem, and try again.

Hi, how do you build a cross compiler environment in linux host pc? Please give us some tips/steps.

what is kermit -c in ?
