Did anyone managed to have this library working with S3? My board keeps crashing on Can0.begin() so I am guessing it's still not fully compatible ?

works for me with my adjustments

Tried your path-1 branch and same result - ESP32 S3 keeps rebooting on CAN0.begin()

I;ve used this code, but without BT stuff

Also I've managed to get CAN bus read with TWAI example from here

Same, like I've mentioned - it crashes on setup on CAN0.begin(500000);

I have the same when using QSPI instead of DIO. I need to check if underlying stuff changed, because it works on my S3. Maybe hardware?

That's the exact hardware I am using

I'm misusing this PR now.
@gbkwiatt Did you solve the crash issue? Got my board a few weeks a go and my board keeps crashing.
