Steve,<br>
<br>
decode your backtraces using the "a2l" script (see support folder)
and the .elf file of the build the crash occured with. The script by
default uses the latest .elf file.<br>
<br>
You can find the crash backtraces of previous crashes on the server
in table "*-OVM-DebugCrash" (kept for 30 days).<br>
<br>
Known crash issues:

<br>
Any help with finding crash reasons is appreciated. I still am under
the impression the PSRAM bug isn't solved for all edge cases, but
also am certain we can find fatal bugs in our code as well.<br>
<br>

<div><br>
</div>
<div>Thanks for the info. Naively doesn't seem like a
javascript program should be able to crash the whole system.</div>
<div><br>
</div>
<div>I did think about rather posting to ABRP from the server
side - IE as data is sent to the server then code on the
server sends the update to ABRP.</div>
<div><br>
</div>
<div>But maybe I buried the lead, which really was to find out
how I can get a lower level view of what crashed the board,
and how to turn those memory addresses into a better idea as
to where in the code the crash occurred.</div>
<div><br>
</div>
<div>Do you know, or Michael can you help?</div>
