Taking a look at the code I saw the error occurs in an "else" part of an "if" statement:

if ( PrimaryCCD.isExposing() )
    {
        non_capture_frames = 0;
...
}
    else
    {
        non_capture_frames++;

        if( non_capture_frames > 10 ) {
            /* If we arrive here, PrimaryCCD is not exposing anymore, we can't forward the frame and we can't be aborted neither, thus abort the exposure right now.
            * That issue can be reproduced when clicking the "Set" button on the "Main Control" tab while an exposure is running.
            * Note that the patch in StartExposure returning busy instead of error prevents the flow from coming here, so now it's only a safeguard. */
            IDLog("%s: frame received while not exposing, force-aborting capture\n", __FUNCTION__);
            AbortExposure();
...

So it confirms the CCD should be exposing but indi reports it is not, although I can see the LED is on for the time of exposure and the error message says it's receiving frames in the error message...

I'm lost here, if anyone can shed a light on how frames should be grabbed and what can lead to this error? Is it the capture which doesn't happen at the right time? could it be indi v4l2 driver which do not talk to the device appropriately? Or could it be my mod which is just not right? (BTW, here is the mod I used: spc900 LED mod LXhttp://www.astrosurf.com/djibb/new/modif.htm
