    Has anyone seen this issue? We have been running these devices with version 8 and had no issues ever. Now we got a new batch with version 9 on, and it seems the device can get "stuck" or silent.

    See this sequence

    >ver
    00000009
    >id get
    00000002
    >gpio read 0
    >gpio notify off
    gpio notify disabled
    >gpio readall
    >gpio notify get
    gpio notify disabled
    >gpio notify on
    gpio notify enabled
    >gpio readall
    >ver
    00000009
    >

    If I unplugg and replugg the device it works again. I think it is triggered på "gpio iodir" in a certain sequence

    Hi Niclas,

    This was confirmed to be caused by a compiler related problem (potentially a compiler bug). We have shared V8 image over the ticketing system. Hopefully that fixed the issue. If there are any difficulties still, please drop us a line.

    Thanks,

    Yes, we downgraded to V8 and did not have any issues anymore, so that makes sense. The problem we face now is that we have about 200 units. Is there a scriptable way to do this or is the UI program the only way?

    We have a lot of these we need to downgrade to V8. Where can I get version 8 and instructions on how to downgrade the version?
    Thank you.

    I am also getting a similar problem where setting a pin will get stuck and the board becomes unresponsive. How do I check the firmware version and put V8 onto my GPIO board? Thanks.
