Mark,
good example why not to use addr2line: I think that result is wrong. a2l uses gdb which gives:
balzer@leela:~/esp/Open-Vehicle-Monitoring-System-3/vehicle/OVMS.V3> a2l tmp/3.2.007.ovms3.elf 0x400d5e4c:0x3ffc5c40 0x7ffffffd:0x3ffc5c90
Using elf file: tmp/3.2.007.ovms3.elf
0x400d5e4c is in CAN_rxtask(void*) (/home/openvehicles/build/Open-Vehicle-Monitoring-System-3.1/vehicle/OVMS.V3/components/can/src/can.cpp:730).
725 me->IncomingFrame(&msg.body.frame);
726 } while (loop);
727 break;
728 }
729 case CAN_txcallback:
730 msg.body.bus->TxCallback(&msg.body.frame, true);
731 break;
732 case CAN_txfailedcallback:
733 msg.body.bus->TxCallback(&msg.body.frame, false);
734 msg.body.bus->LogStatus(CAN_LogStatus_Error);
…and that actually makes sense and matches the register dump.
If I read the gdb disassembly correctly, A10 = msg.body.bus, so Greg's got a CAN_txcallback msg without a bus.
Hardening the rxtask against null here would probably avoid the crash, but I don't see yet how that could be possible.
Both esp32can and mcp2515 set the bus field to their object addresses, which cannot be null.
Regards,
Michael

Can’t get a2l working at the moment. The addr2line gives:
addr2line -e 3.2.007.ovms3.elf 0x400d5e4c:0x3ffc5c40 0x7ffffffd:0x3ffc5c90/home/openvehicles/build/Open-Vehicle-Monitoring-System-3.1/vehicle/OVMS.V3/components/can/src/can.cpp:551
That is:
void canbus::LogInfo(CAN_log_type_t type, const char* text){MyCan.LogInfo(this, type, text); <—— HERE}
ELF is at:

_______________________________________________Mark,
Greg uses your build, the crash point seems to be consistent, can you post the a2l on this?
Regards,
Michael
PS: Greg, would you mind switching to EAP to beta test future releases?

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
