Zero 3W Camera 8M doesn’t work

Viktor_Nikitin · August 29, 2024, 2:35pm

Hello everyone!
Has anyone managed to start the camera on the Radxa 3W board?
I am testing on Debian b6
with an update via rsetup (after the update, overlays from radxa 8M appear)
I have 4 GB RAM 32 eMMC
I am testing the following cameras:
Original RADXA 8M, rspb camera 1.3, rspb camera 2
When switching cameras, I select the corresponding overlay.
When connected, the radxa 3w board starts to heat up a lot (much hotter if the camera is not connected). Is this normal or a defect?
And sometimes the Radxa 3W does not start at all with the camera connected.
I try to test the camera via cheese, via rsetup
by starting the RTSP server via the link
https://docs.radxa.com/en/zero/zero3/app-development/rtsp
I used different device addresses: video0 video-camera0 etc.
Errors and other things are everywhere.
Maybe someone has encountered and solved the problem? or I have a defect in the Radxa 3W itself.

can you send a picture how it is connected, right now I guess you have a radxa zero3w version which has the wrong connector

yes, this one is inverted, either you let them refund you or you search for a cable with inverted pins.

It’s a wrong connector on the pcb it should be flipped :

Ok, thanks for the clarification.
Now when ordering I will specify what type of connector.
I will use this board for other purposes.
I think it will be difficult to find an FPC with an inverted connection.
However, it would be nice to indicate the revision on the board, so that it is clear what you are ordering.

it’s not an revision, but a manufacturing defect

I ordered a second board, it came with the same defect, I will try to arrange a return,
I noticed that the packaging has an indication of the revision,
revision from 1.120 my connector turned out to be defective.
Are there revision numbers where the defect was fixed? so that I can immediately write to the seller

Or you can send me the correct part number of the connector, I will order it and resolder it

I’ve managed to make Radxa Camera 8M 219 work. My approach is probably far from the optimal one, but it works. Image used: radxa-zero3_debian_bullseye_xfce_b6

sudo rsetup -> System -> System Update
cd /lib/linux-image-5.10.160-26-rk356x/rockchip/overlays/
sudo cp radxa-zero3-rpi-camera-v2.dtbo /boot/dtbo/
sudo u-boot-update
Change default to l1 from l0 in /boot/extlinux/extlinux.conf. l1 target should point to linux image 5.10.160-26-rk356x instead of 5.10.160-38-rk356x.
sudo reboot
Check kernel version with uname -r it should be 5.10.160-26-rk356x
sudo rsetup -> Hardware -> Video capture devices -> vide-camera0 -> Show live video

Remarks:

This approach could fail if FPC cable is not connected properly OR FPC wiggles inside MIPI CSI and connection is loose.
All of my cameras on Radxa Zero 3 work only on kernel 5.10.160-26. The list contains only cameras with sensor IMX219 - Overlay RPi Camera v2.0 and OV5647 - Overlay RPi Camera v1.3)
