<p>maybe it is easiest for developing on some boards which has UART port to look it boot up message.</p>
<p><br>
</p>
<p>some mt6572 based boards one can find on China market. they event can share code with us if we buy it.</p>
<p><br>
</p>
<p>it is android based. </p>
<p><br>
</p>
<p><br>
</p>
<p>so should/can we make a osmocom-bb based BP for this android board? or other smartphone?</p>

<div class="PlainText">I don't have the files mentioned in that patch. They look very much like some part of an Android source code tree. So far I am working mostly not with Android at all... only osmocom-bb, nuttx, fernly and fernvale-nuttx.<br>
<br>
My work on the newer MT chip in the ZTE Obsidian is a ways down the road. One thing that was VERY encouraging is that I have tested the beginnings of interaction with it's bootloader (as in the fernly project)<br>
and it seems at least the initial MSG and ACK from the bootloader works the same as for fernly types of MT chips (6260/6261). So that might be a good starting point in terms of experimenting/fuzzing/???<br>
<br>
Maybe you could find a custom rom source tree and find those files that are being patched.<br>
<br>
In terms of participating in my project, I have a github repo and am primarily using the fernvale board I purchased from sysmocom as well as some mt6260/6261 based watches and the Seeed Studio RePhone.<br>
<br>
So I'd say go get one or more of those things and start hacking on fernly, fernvale-nuttx, osmocom-bb and nuttx-bb (combo of osmocom-bb and nuttx).<br>
<br>
I don't work too hard on the project. This branch is my latest not-working work in progress:<br>

I have since changed my strategy and so this branch will likely rot. :( But it might give some indication of what I'm up to.<br>

My target was Mt6735 in a Zte Obsidian. I chose it for<br>
4g lte. I could root one and see if similar techniques work.<br>
My hope was to leverage leaked source for mt626x and hope to<br>
work my way up the chip models. I am currently working on<br>
porting osmocom-bb<br>
and nuttx-bb to fernvale/rephone/mt626x.<br>
