Copter: CANFD data stream hangs up after couple of minutes. about ardupilot HOT 6 CLOSED

Update: If I use CANFD at 1Mbps. I am getting continuous stream. The issue comes at 5Mbps.

How are you determining that it hangs? Just that the received count stops increasing? Does it always stop after the same count? It would be useful if you could also upload the script.

I ran luacheck on your script, it finds a few issues:

    scripts/CAN test.lua:2:7: unused variable update_rate_ms
    scripts/CAN test.lua:10:7: unused variable get_xy
    scripts/CAN test.lua:11:1: setting read-only global variable type
    scripts/CAN test.lua:41:16: unused function pow2
    scripts/CAN test.lua:58:21: accessing undefined field ldexp of global math
    scripts/CAN test.lua:94:10: setting read-only global variable type

It would be useful to double check the script is still running. Can you enable disarmed logging and set SCR_DEBUG_OPTS bit 3 (value 8) for "log runtime memory usage and execution time".

Hi @ketanatzebu,

I'm not too familiar with this area of the code but I guess you tried modifying the CAN_P1_FDBITRATE parameters and it didn't help?

.. anyway, I guess this is resolved so I'm going to go ahead and close this issue if that's OK. I've ping'd other developers to get their input on whether we should support 5Mbps or not.

Yes, I configured my sensor for 1Mbps and changed the param CAN_P1_FDBITRATE to 1M.
