Hi,
We are using the Model S front motor control board by Damian McGuire and the included ESP32 CAN Wifi board.

We notice intermittently when both boards are powered up the Web interface complains that the CAN connection is not working.

Do these two boards need to be powered up in a specific order? Another known issue?

Moved to "User interface" forum. Please put topics in appropriate categories

Can you post a CAN log when it's not working?

There is no specific power on pattern, can be simultaneous or one after the other
