From power-up, PiCapture seems to work fine on either of my RasPi-2 or RasPi-3 systems using raspivid to do a preview. However, if I reboot the Pi (either one) with the blue light on, then executing subsequent raspivid commands yields a mmal_vc_component_create error, ending with ‘Camera not Detected’. Only a shutdown and full power cycle will get if working again. Again, the blue light was on when the reboot was done.
Thanks again for reporting this. It appears that a Raspberry Pi linux reboot does not completely clear all settings in GPU portion of the processor. We have a fix for this on the PiCapture side, and will include it in our next release of the firmware when testing is complete.
OK thanks for the quick work on it. I can use the fix as soon as its available. I think you’ve done well to utilize the GPU in any case. I know some aspects of the Pi hardware are not as well documented as one might wish.
We are not seeing this issue with the HD1 in our test system. Is the PiCapture board responding to PiVideo after the RPi reboot? If you would send the details of your configuration and the steps to create the problem we will look into it. It is important to include tha status of the LEDs on the HD1 board.

The situation was that the capture was working fine ( one flashing led , 3 solid ).
I was updating raspbian , and going through a few reboots.
Next time I tried capture ( raspivid or raspistill ) I got an error about MMAL ENOMEM
A shutdown , remove power and re-power cleared the problem , and everything worked as normal.
