picamera.exc.PiCameraRuntimeError: Received unexpected camera control callback event, 0x4f525245

[tuttoweb]

Dear all,

I have bought a IVPORT v2 multiplexer and I am having problem to make it work. Specifically, it worked once, then I rebooted and, after that, it did not work anymore. I get this error

$ python test_ivport.py Traceback (most recent call last): File "_ctypes/callbacks.c", line 314, in 'calling callback function' File "/home/pi/Desktop/Phenotiki/env/ivport-v2/picamera/camera.py", line 129, in _control_callback "Received unexpected camera control callback event, 0x%08x" % buf[0].cmd) picamera.exc.PiCameraRuntimeError: Received unexpected camera control callback event, 0x4f525245 Traceback (most recent call last): File "test_ivport.py", line 60, in main() File "test_ivport.py", line 56, in main picam_capture() File "test_ivport.py", line 33, in picam_capture iv.camera_capture("picam", use_video_port=False) File "/home/pi/Desktop/Phenotiki/env/ivport-v2/ivport.py", line 142, in camera_capture self.picam.capture(filename + "_CAM" + str(self.camera) + '.jpg', **options) File "/home/pi/Desktop/Phenotiki/env/ivport-v2/picamera/camera.py", line 1619, in capture 'Timed out waiting for capture to end') picamera.exc.PiCameraRuntimeError: Timed out waiting for capture to end

This is what I get with i2cdetect $ i2cdetect -y 1 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- -- -- -- -- -- 10: 10 -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- 64 -- -- -- -- -- -- -- -- -- -- -- 70: 70 -- -- -- -- -- -- --

and this with vcgencmd $ vcgencmd get_camera supported=1 detected=1

Everything should work, but apparently something is off and I cannot figure out what is wrong.

Below you'll find a pic of the system. I chose the setup A as jumper.

Thanks a lot for your help

I'm getting the same issue as well - really wish IVmech would provide some information on this issue. I can't get the board to work properly and everything is setup right. I'm getting the same error you are.

I am also experiencing this same problem

DId you also try the test_ivport_quad.py script?

Hi everyone - running into the sqme problem; has anyone fixed the issue?

[ggriffon]

I have the same issue

I had the same issue with test_ivport.py, but with the test_ivport_quad.py worked ;)

I'm having the same issue in my script. I haven't dig into it yet, but the ugly patch that i'm using now is init ivport.IVPORT and the closing it at the begining of my script. I'm using capture_continuous and camera capture in my script.
