Well... check the .config or the kernel sources for CONFIG_EARLY_PRINTK or CONFIG_WANT_EARLY_SERIAL Have a look at the bootup code of your board, where it's used. I would call the printk as soon as the serial ports are initialized. If that's too late, try to toggle some pin as early as possible. If that doesn't work, and if you have no more ideas of what to do, you might think about getting some hardware debugging tools.
