5.Has your product ever worked properly?
Never Worked yet
6.What problems are you experiencing?
Hi ArduCAM Team,
I bought 5 AR1820HS camera on UCtronics for a current project.
I followed in detail all the instruction of this page :
https://github.com/ArduCAM/MIPI_Camera/tree/master/RPI
everything is fine, until this error message :
‘’’
mmal: Failed to start sensor.
mmal: Failed to enable camera
‘’’
I have already increased the memory for the GPU at 360 M, it doesn’t help.
thank you so much in advance for your help.
see here under all the tests :

7.What attempts at troubleshooting have you already made?
increase of GPU Mem
8.How would you like us to help you?
provide me simple instructions that are working, indications what else to try, which tests to make to have more infos etc…
