Hi All,

I have ported the latest linux kernel to s3c2440 (linux-2.6.24..4).  And I used the latest snapshot of buildroot to make a cpio filesystem.. But the shell prompt does not come. The compilers used for building the kernel and the filesystem are different. The one used for buildroot is a uclibc version. Following is the whole output.

DRAM:  128 MB
Flash: 32 MB

Out:   serial
Err:   serial

When I hit the Enter key, nothing else appears. But the keyboard is active.
What could be the problem?
