Hi Joseph,

Which board are you using? Did you check that CAN driver is available for this board?
Not sure it has been deployed for the whole STM32 family.

With some more debugging it looks like the STM32 CAN initialization
fails in the STM32 HAL code: At HAL_CAN_Init() the loop waiting for the
INAK bit in the CAN_MSR register to be reset when the initialization
mode of the CAN controller is left. This works with another program (not
using Zephyr) on the same board so I do not expect that my hardware is
broken.
