Thank you first of ally your responses. I haven't unfortunately JTAG component right now and also the equipment like Matthias mentioned. How about the fastboot? Is it also possible to use fastboot for sending
android
image? l4 generates bootstrap_L4LinuxARM.elf file, and we can convert
this
image file into the u-boot image file as explained in [1] with the following command.
There's a fastboot make target, so you can just issue: make fastboot E=... and it will load the rawimage using fastboot.
I converted it but it seems that either the given address is not true or
this method doesn't work.
Typically rawimage must be used with fastboot but there are also cases for uimages (use 'make fastboot_uimage' then), it depends. In your case it loads fine but then nothing happens on the target? If that's the case it's just guessing what could be the cause...
I used fastboot and the message whet I try to load the image is as below

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.

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. Cem
