If you don't have the kernel messages after this, then it means that
something is wrong in your configuration. Don't expect to see anything
on the video output before you get your kernel to boot properly, i.e to
display messages on the serial console after "Uncompressing Linux...
done, booting the kernel".

However, this discussion is really not Buildroot-specific, it is really
about configuring a kernel for a particular hardware platform, so you
should probably rather ask in support places (forums, mailing lists,
etc.) that are related to this particular piece of hardware.

Best regards,

Thomas
