Just replace the two attached files in your local repository and rebuild the library.
Pl. send me feedback if it works or not.

/Binaries/can_test "Kvaser CAN Channel 0" -r

but It didn't work. What is the cause?

Available interfaces are printed. (Kvaser CAN Channel 0)

Have you rebuild everything by make clean ; make all?

To isolate the problem, it is better to use the trial program with option INFO: ./Trial/kvl_test TEST INFO
There is more babbling ;)

@mac-can sorry for late reply. Sir I checked again and it seems I am still getting the error.
My OS is using Mac OS M1 (ARM) 13.0 (22A380) version.

Can you do some CAN monitoring to see if this is working?

I used can_recv.py in the Examples/ directory to test it. but it doesn't seem to work

Your device is detected and added to the device list:

  Loading the MacCAN driver...
   - One device added at location 01140000
     - Device #0: Kvaser USBcan Pro 2xHS v2
       - Properties: vendor = bfd, product = 108, release = 0001, speed = 2
   - Run loop started so notifications will be received

Also the MacCAN core layer has done its job:

    + Device #0: asynchronous event source added to run loop
       - Message pipe of size 512 bytes
       - Message queue for 65536 elements of size 88 bytes
       - Double buffer each of size 512 bytes for endpoint #1

But I miss one log message before the error message:

+++ error: myDriver.InitializeChannel(0) returned -95
Cheers!

The trial program should print the following line before calling myDriver.InitializeChannel:

    Initializing Kvaser Leaf Pro HS v2 driver...

It seems that the configuration settings are not correct.

If you have the possibility to debug the trial program, you can set a breakpoint on function Mhydra_ConfigureChannel in the file KvaserCAN_Driver.c (line 106) and step through it to see which parameter causes the error. Or place some printf statements in the function.

Happy debugging ;)
