Can anyone successfully build this samples/drivers/can/babbling for any espressif board?
Moving to some ethernet work while I wait on that.

The CAN transceiver is a TJA1050. Doing comms between an esp32 and a bluepill

Don't have one on me. Resorted to the good old multimeter, testing between CAN HI and GND then CAN LO and GND. For this transceiver, when connected to one of the devices I am testing the voltage between HI and gnd should be between 2.5 and 3.0 and LO abd gnd should be 2.0 and 2.5. Values I get are very low in the range of 0.8 - 1.1

Oh shoot my transceiver is faulty. I am getting very around 0.8 and 0.9 voltages between can hi and gnd.

Everything is properly wired up but I am getting these from the bluepill. Will need to get a logic analyzer to see if CAN TX/RX signals between the chip controller and the CAN transceiver.

we are a-building. Enabling status in the overlay solved it 
&twai {
      status = "okay";
};
