Considering the given output, it seems that the boot.img is loaded but
booting process cannot start. I applied the same steps for uimage instead
of elfimage and the result is again the same as below.

akpolat@akpolatX240:~/mysvn/arm_l4android/src/l4$ make fastboot -C

These outputs raise of course some questions such as I really load the
image into the right address or I use the right command for the
compilation.

In all above mentioned cases, what I am see is only the Google log along
with a lock on the screen.


Thanks again for your quick reply.
