you need to keep the .elf files for your builds to be able to

Extending Mark's answer:<br clear="none" class="yiv5468089902">
<br clear="none" class="yiv5468089902">
It's normally OK to directly set metrics from IncomingFrameCan1(),
but be aware metrics listeners will be executed synchronously in the
context that changes the metric.<br clear="none" class="yiv5468089902">
<br clear="none" class="yiv5468089902">
Standard metrics listeners are now for example the automatic
notification generators in the vehicle base class. These may need
quite some stack and time.<br clear="none" class="yiv5468089902">
<br clear="none" class="yiv5468089902">
If you spend too much time handling frames on a high volume bus,
your vehicle task may lose frames. It's possible to raise the queue
size (currently 20 frames) and the vehicle task stack size, but it's
better to keep the CAN processing simple.<br clear="none" class="yiv5468089902">
<br clear="none" class="yiv5468089902">
TL;DR: if you need to handle many CAN frames, I recommend changing
metrics that trigger notifications or other complex actions from the
ticker. If you encounter crashes on some CAN frames that may be due
to the vehicle task stack being too small
(CONFIG_OVMS_VEHICLE_RXTASK_STACK=6144).<br clear="none" class="yiv5468089902">
