Have noticed that the CAN1 with MCP2515 is not receiving all messages send on the bus.
Tested with just 4 different messages all running al 10ms.

Switched the interrupt to core1 and now it seems stable
xTaskCreatePinnedToCore(&task_MCPInt15, "CAN_INT_M15", 4096, this, 10, &intDelegateTask, 1);

Also have Wifi enabled which also runs on core0

As soon as CAN0 starts to transmit can frames CAN1 starts to missing received messages.

Are interrupts disabled when CAN0 transmits?
