<p>From what you posted to the matrix channel it sounds like the
board is not getting past u-boot.</p>

<div>I think there has been some eMMC corruption so this is also
highly likely.</div>

<p> If you point me at the image you used I might be able to
diagnose it without you connecting the debug header.<br>

<p>Soldering on the debug header will make debugging way
easier.</p>

<div>I think at this point this seems like the best approach.</div>

<div>I've ordered headers from Digikey and am going to test a
quick and dirty approach to see if I can get up and running
again.</div>

<p>I'm not sure what image you've tested with but I just flashed
this one and it boots no problem</p>

<p>If your devkit doesn't boot with this then we'll need to use the
debug header to figure it out.</p>
<p>Either one of these cables<br>

should be up and running tomorrow.<br>

<div>In the meantime I'd like to continue to be able to help Todd
test and am thinking about getting another iMX8 quad device. I
wonder what people think about this one; </div>

<div>This is the same CPU and the same SoM I believe as our phone
so it seems appropriate. It obviously does not have a screen but
I have a 7 HDMI touch screen that I believe I can use with this.
This may turn out to be an interesting way to test convergence
or adaptive applications since the screen is a different size
from the phone.</div>
<div><br>
</div>
<div>What do others think?</div>
<div><br>
</div>

<p>I think adding yet another device to our testing won't really
help. Either the bugs will be devkit specific or they will be
iu/userland/rootfs bugs. The second class of testing could largely
be done with the qemu images.<br>
