Did you guys have some unresolved bug with the CAN driver v1.4 ?

Actually I’m using a GCX v4.20.16

I want to read CAN msgs, not to fast as I receive it (so I will use the internal driver buffering functionalities [less than 5000 msg] and read multiple data at one time with EV_DATA_RDY0, IOCTL_CAN_GET_NUM_MSGS & ReadFile)

If I stop the external CAN transmission I have not received all CAN msg and I’m sure that there still some message in the CAN mailboxes but when I use then IOCTL_CAN_GET_NUM_MSGS and the ReadFile it doesn’t return any msg.

If I restart the external CAN transmission I’ve got some old data in front of the new data

I just wondering if you’ve seen problems like that..

Thanks

Phil

Hi Phil. We're in a cycle of CAN testing right now, shaking out issues from the drivers in a number of our products (VGX, AGX, GCX, Sphere). You had also reported an issue a while ago in which the GCX app would crash the system if the touch panel was used while there was heavy CAN traffic.

We are looking at these and other CAN-related issues and will keep you posted as they are resolved. We may contact you if we need further details about what you are seeing.
