[Ovmsdev] Twizy / 500 kbps CAN lockups

During my tests I had two times some sort of a CAN lockup, i.e. everything worked except the CAN reception -- was fixed by switching the car off + on.

I'm not sure yet what caused that, it (of course) did not happen again since I included a first debug output of the RXERRCNT...

I saw the 1 mbps setup does not follow the intrepid timing calculator standard parameters but increases prop delay from 1 to 3 and decreases phase 1 from 5 to 3.

A similar change to the 500 kbps parameters though did not work with the Twizy.

Do you have any hints on debugging this?

My current setup for 500 kbps is:

 // 500 kbps -- tool recommendation + multisampling:
 BRGCON1 = 0x00;
 BRGCON2 = 0xFA;
 BRGCON3 = 0x07;

Thanks, Michael
