<br>
as there was some discussion on irc, I would like to ask, if you
did some further work an reverse engineering?<br>
<br>

<div>Hi All,</div>
<div><br>
</div>
<div>I've been slowly working at reverse engineering the
libvecore.a cedarx library based on the resources we have
available. </div>
<div><br>
</div>
<div>As a start I've created a working (although really not
finished) memory allocator (libcedarxalloc.a) which is used by
libvecore.a to allocate and manage memory reserved for use for
the cedarx a10 decoder chip.</div>
<div><br>
</div>
<div>I've built and tested this against the code available here: <a
moz-do-not-send="true"
href="https://github.com/amery/allwinner-a10-video">https://github.com/amery/allwinner-a10-video</a>.
My code is available here <a moz-do-not-send="true"
href="https://github.com/iainb/open_cdxalloc">https://github.com/iainb/open_cdxalloc</a> </div>
<div><br>
</div>
<div>I'm fairly certain the original code from amery's repo is
broken in some way. Even unmodified code causes random kernel
panics, probably caused by some kind of memory corruption. The
libvecore.a library manages low level access to memory and the
video decoder core so its possible there could be problems there
- though that's just a guess, at least its very easy to
reproduce.</div>
<div><br>
</div>
<div>If anyone can provide me with more better resources such as a
working libvecore.a (unstripped for development and testing
would be nice!) or more documentation then I would be very happy
(it doesn't hurt to ask right?).</div>
<div><br>
</div>
<div>Thanks,</div>
<div><br>
</div>
<div>Iain.</div>
