I've appended some can messages from the log file on my sd card. 
Timestamps correspond to when I was driving. Looking at esp32can.cpp I 
guess errflags (aka error_flags) is a combination of several things, 16 
bits of "error_irqs", 8 bits of MODULE_ESP32CAN->SR.U, and 8 bits of 
MODULE_ESP32CAN->ECC.U. I think 0x800000 is BIT(7) or __CAN_IRQ_BUS_ERR 
or "IR.7 Bus Error Interrupt".

Is it saying it doesn't like my can bus? I haven't changed the way I 
connect to the high speed can, I tapped into the onstar connector. I 
guess it's possible the cable got damaged (it's under the 
right/passenger's seat) but it does seem to be able to receive frames 
without error. (And I know the engine will not run if there are problems 
on the high speed can bus!)
