Very likely your kernel is booting, but you do not have specified a serial console, so you do not see any output. Can you show us the exact sequence of commands booting the kernel, i.e. especially show us the bootargs U-Boot variable. You can also try the post mortem log buffer examination[1] to see what kernel messages were generated.
