Thanks for the update.<br><br>I'm travelling quite a bit during the next couple of weeks. I'll try to take a look at what you have done. Please continue to post your progress. It is very helpful.<br><br>What limitations are imposed by using QEMU? Is the low-level boot process represented in the emulator? Does it emulate the stepping-stone load and execution? What is the best way to debug the boot procedure? Can you single-step through the boot sequence in QEMU? How are the LEDs represented in QEMU? Since controlling their blinking is your initial focus, I'm wondering how to observe that without the GTA02 hardware.<br>
<br>There's a lot of code in the u-boot tree. I have been reading through it and trying to get familiar with what is already there, even though much of it is not necessary for basic functionality. <br><br><div class="gmail_quote">

i think i finish the Werner first step.<br>
the code is here <a href="http://git.openmoko.org/?p=kboot-stage1.git;a=summary" target="_blank">http://git.openmoko.org/?p=kboot-stage1.git;a=summary</a><br>
and i begin to add start.S and friends<br>

you can find current U-Boot sources (start.S and so on) here:<br>

<a href="http://git.openmoko.org/?p=u-boot.git;a=shortlog;h=stable" target="_blank">http://git.openmoko.org/?p=u-boot.git;a=shortlog;h=stable</a><br>
<br>
You can clone them like this<br>
<br>
git clone git://<a href="http://git.openmoko.org/git/u-boot.git" target="_blank">git.openmoko.org/git/u-boot.git</a> .<br>
git checkout origin/stable<br>
<br>
the start.S is in path/to/uboot/cpu/arm920t/start.S<br>
