Are you sure you are using a cross compiler for ARM (e.g. those from
Emdebian or from Code Sourcery) and not a native compiler?
AFAIK, the NOKIA logo does not say anything whether the kernel is
booting, it comes from the bootloader. And its probably rebooting
because a hardware watchdog is being triggered due to a buggy kernel.
