Environment
- python-can: 4.6.1
- Hardware: Kvaser Leaf Light v2 (S/N 87702)
- OS: Windows 11
- Python: 3.12
Description
Initializing a KvaserBus fails with CANLIBOperationError on multiple canIoCtlInit
calls during init. The following ioctls all fail with Error Code -1 (canERR_PARAM):
- canIOCTL_SET_TIMER_SCALE
- canIOCTL_SET_LOCAL_TXECHO
- canIOCTL_SET_LOCAL_TXACK
Reproduction
bus = can.Bus(interface='kvaser', channel=0, bitrate=500000)
Traceback
CANLIBOperationError: Function canIoCtl failed - Error in parameter [Error Code -1]
at canlib.py:568 -> canIOCTL_SET_LOCAL_TXACK
Notes
Kvaser CANKing connects successfully to the same device on the same channel
with Init Access mode. The device is detected correctly, python-can lists it
as channel 0. The failure is in the ioctl calls after canOpenChannel succeeds.
