Hello list,
We have a problem with packets that appear to be being dropped with no errors.
We are running on an RPi3 and have used 2 different CAN interfaces, 1st a
CANBerry v2.0 board based on a Microchip MCP2515 on I2C and 2nd an EMS_USB
using an NXP LPC Arm chip.
I'm monitoring the CAN bus using a Peak PCan interface into a Windows PC.
In cases using both RPi3 interfaces I see a 60x write request go out to a node,
the 58x response come back from the node and then some time later CanFestival
issues a 60x 80 cancel request. I have not received an error to the call
requesting the OD write. It seems like I should get some kind of an error back,
dropped packet, overrun, timeout, something.
Am I missing something in setting up the interface to CanFestival, do I need to
set up an error callback?
