<div class="">Odd.<br class=""><br class="">Wonder which bus it was that it didn't have? I might try disabling the auto start of the obd2ecu task, and see if that changes things.

good example why not to use addr2line: I think that result is wrong.
a2l uses gdb which gives:<br class="">

a2l tmp/3.2.007.ovms3.elf 0x400d5e4c:0x3ffc5c40
0x7ffffffd:0x3ffc5c90<br class="">
Using elf file: tmp/3.2.007.ovms3.elf<br class="">
0x400d5e4c is in CAN_rxtask(void*)
(/home/openvehicles/build/Open-Vehicle-Monitoring-System-3.1/vehicle/OVMS.V3/components/can/src/can.cpp:730).<br class="">

</tt><tt class=""><br class="">
</tt>…and that actually makes sense and matches the register dump.<br class="">
<br class="">
If I read the gdb disassembly correctly, A10 = msg.body.bus, so
Greg's got a CAN_txcallback msg without a bus.<br class="">
<br class="">
Hardening the rxtask against null here would probably avoid the
crash, but I don't see yet how that could be possible.<br class="">
Both esp32can and mcp2515 set the bus field to their object
addresses, which cannot be null.<br class="">

Greg uses your build, the crash point seems to be
consistent, can you post the a2l on this?<br class="">

PS: Greg, would you mind switching to EAP to beta

<pre class="moz-quote-pre" wrap="">Hi folks,
Well, the module updated to 3.2.007 last night. I just checked on it,
and it appears that it didn't exactly survive. Crashed while running
the autoconfig script. Log with two cycles attached.
I tried renaming the /store/events directory to /store/was_events since
it seems like Duktape was getting in the way, but that didn't resolve
the crash. I manually enabled wifi so I could manage the module, and
moved it back to 3.2.005 from the other partition. Seems stable again.
The car is going into the Service Center tomorrow (the perennial issue
with 1146 alerts), so I need to have the module stable so that I can
keep an eye on it. Going to leave it on 3.2.005 for now, unless someone
has a quick fix in the next few hours...
Otherwise, any ideas for troubleshooting after I get the car back back
(hopefully end of day)?
Greg
