I was having trouble getting this working on an STM32L496. I had set up CANopenNode on CAN2 and it was transmitting fine but not receiving. After lots of debugging, I discovered this issue.
In CO_driver_STM32, the FilterBank needs to be changed depending on the CAN peripheral. It should be 0 if using CAN1 and 14 if using CAN2. The following preprocessor switch statement looks like it's supposed to take care of this:

In
CO_driver_STM32
, theFilterBank
needs to be changed depending on the CAN peripheral. It should be0
if usingCAN1
and14
if usingCAN2
. The following preprocessor switch statement looks like it's supposed to take care of this:However, even in a dual-bank CAN device,
CAN
is defined. Here is the instance instm32l496xx.h
:This MR changes it to check instead if
CAN2
is defined, which should work on both single-CAN and dual-CAN devices.
