Dual OV13850 cameras finally land on Firefly-RK3399 in Ubuntu 18.04!

@ballsystemlord  So you are mentioning the user space support of the cameras.
Good question! Actually, the deb packages in Ubuntu are ported from the buildroot
repository in github.com/rockchip-linux, where the gstreamer and camera-engine-rkisp
are contained. You can check it out for reference.

Are there any performance issues?

@hsedidin
Performance issue depends on the context.
Both cameras use different MIPI controller with 2 lanes,
the bandwidth not being a problem.
The preview using gstreamer is smooth.

i tried to use an other image ( the last one : FIREFLY-RK3399-UBUNTU18.04-GPT-20190216-1136.img)
look like it's not working i get the following error when i do the sudo bash dual-camera-setup.sh :
E: Unable to locate package libdrm-rockchip1

i tried to continue but it end up in an other error :
XCAM ERROR gstrkisp.cpp:699: Can't find controller, maybe use a wrong video-node or wrong permission to media node
Caught SIGSEGV
XCAM ERROR gstrkisp.cpp:699: Can't find controller, maybe use a wrong video-node or wrong permission to media node
Caught SIGSEGV
exec gdb failed: No such file or directory
exec gdb failed: No such file or directory

( the 2 camera are connected to the board and i did the update/upgrade of the board )
a helping hand would be welcome :p

FIREFLY-RK3399-UBUNTU18.04-GPT-20190216-1136.img has preinstalled the debs mentioned in the setup script.
However, the kernel is not built with dual cameras patches.
You can remove 'libdrm-rockchip1' line in dual-camera-setup.sh and rerun.

Or run the following lines only to update the kernel:

1. 
   
2. wget http://wiki.t-firefly.com/firefly-rk3399-repo/dualcamera/boot.img
   
3. wget http://wiki.t-firefly.com/firefly-rk3399-repo/dualcamera/md5sum.txt
   
4. md5sum -c md5sum.txt || echo "md5sum check of boot image failed!"
   
5. dd if=boot.img of=$(ls /dev/mmcblk?p3)
   
6. sync
   

Copy the code

I tried to update the kernel but after the reboot to have the new kernel take effect, the monitor shows me a black screen :/
I checked that the monitor detect the firefly rk3399, no problem on this side.
To get out of this black screen I have to erase the flash and flash the Ubuntu 18.04

Plz try to build the kernel:

   https://github.com/FireflyTeam/k ... le-4.4-rk3399-linux

So that you can bisect the problem.

hey long time no see.

I try to make it work for the laters version but I give up on this one.

I came back to the older version. It work for only one camera. I got an issue when both cameras are connected one of them doesn't want to start :/

did you try somethink new ?

I have a problem:
I have  just put the lastest kernel boot.img into my firefly rk3399 board,but it display the flip and mirror video .I try to modify flip and mirror regulation 0x3820 and 0x3821,but it did not work either。

Hi,
I'm understanding OV13850 camera entry in the device tree. And I found two different entries in the device tree.
Is anyone can explain the difference between the two camera entries?

1. from ./rk3399-firefly-linux.dts (or) ./rk3399-rock960-ab.dts
        camera0: ov13850@10 {
