Not Able to connect Camera

ROCK 3 Series CM3
1

I am using radxa development board for CM3, and the board has MIPI CSI connector I believe.
and would like to use camera with that connector.
Below are the image of connector which i have for camera and for board.

Could you help how to connect the camera to board, if this is not the correct connector, anyone help me with which connector to get and link for that if any,
I am using IMX219 camera sensor from picamera V.2 version module,
If this is the wrong camera That i am using, let me know which one works fine.

Any help is highly appreciated.

Thanks.

Ahh sorry, I always thought they would be raspberry compatible. … With this connectors you’re pretty much … stuck.

You can create a adapter pcb and print it, but it’s just cheaper to use another carrier board which is compatible with raspberry cameras

I use the waveshare nano B

Any suggestions how to make usb ports work.(for keyboard and mouse)

Thanks

the RK-dev tool can not flash sd-cards, you need to use etcher or any other tool for that.

The usb-stuff is a known issue, it is not working on most carrier boards, I have made mine work with a special kernel and a little magic, the official way to get it working is this :confused:

you have to add a device tree overlay, on new images you can do that with rsetup

I have solved the camera issue now, I am facing with SD card issue,
I have loaded the firmware with through RKDevtool,
After loading the firmware i want to access external sd card.

So when I connect with radxa CM3 IO board, its detecting the TF card.

but when I connected to waveshare board.
i am using this board
https://www.waveshare.com/cm4-to-pi4-adapter.htm

and its not able to detect the TF card.
As it seems like we have to enable SDMMC0_PWREN.

any ideas how to enable this, so that i can able to mount my sd card.
