[libcamera-devel] How to detect camera after power on the raspberryPi.

[Naushir Patuck]

Dear Nomura-san,

Could you provide more details on this board please?  I could not
gather any information from the website you linked.

Firstly, are you using an official Raspberry Pi Camera v2 board on the
other end of this link?  How is the transceiver chip programmed?
Also, what application are you using when you say that you can get RAW
images out of your setup?

Finally, I should note, that this type of questions might possibly be
more suited for the Raspberry Pi Camera forums
(https://www.raspberrypi.org/forums/viewforum.php?f=43) and not the
libcamera mailing list - assuming it is related to the hardware setup
you are using.

Many thanks,
Naush
