banana pi BPI-M3 test ov8865 camera with android image

android image have support ov8865 camera by default , just connect camera module . it working fine.

Weird! This is a new camera module for the M3. You publish a 240p video (320×240 pixels) and even in this downscaled clip it’s obvious that the quality sucks.

yes ,BPI-M3 use MIPI interface ,so we do a new hardware , it have two interface ,can support BPI-M1,M1+,M2,M3,and R1.

It can but it won’t support since this would need drivers and you don’t do drivers, right?

BTW: You’re a tech company. All you guys have smartphones. No smartphone from today allows to record videos with just 320x240 pixels.

Since you provide a downscaled video with just 320x240 pixels and even there it’s obvious that the image quality of this camera module totally sucks: Would you recommend buying this camera module?

  • What’s the maximum resolution for stills?
  • What’s the maximum resolution for video?
  • How many fps do we get?

Not based on the module’s specs but on reality (after the camera output has been processed by drivers/software). Show us a video with appropriate resolution/fps to be able to judge the quality we get.

we have OV5640 camera module work on BPI-M1,BPI-M1+,BPI-M2, all driver is support fine.

OV8865 camera module, we have driver support for BPI-M3 use MIPI interface , working fine on BPI-M3. we will test driver on BPI-M1,BPI-M1+ ,BPI-M2 later. ,

No, the quality is horrible. Both resolution and framerates are too low. The OV5640 is a 5MP module and with the drivers you provide no one ever got resolutions exceeding 640x480 pixels. Your drivers are the problem not the hardware!

And again: Since you transcoded the video showing the results for the new OV8865 camera module down to 320x240 pixels and even with this low resolution artefacts can be seen on the screen it’s obvious that the situation with the OV8865 driver is even worse.

Again: Show us a video with appropriate resolution/fps to be able to judge the quality we get. It’s so easy to do it. All you need is a smartphone. And you guys own smartphones, right?

i, I am using BPI M3 with camera module https://bananapi.gitbooks.io/bpi-accessories/en/bpim3camera.html, following the instructions on https://bananapi.gitbooks.io/bpi-m3/en/bpim3csicamerainterface.html I am able to capture images from ov8865.

However, following the same instructions for OV5640, How to use OV5640 on BPI-M3: Step 1: Install git $ sudo apt-get install git Step 2: Update bpi-tools $ git clone https://github.com/BPI-SINOVOIP/bpi-tools.git5 (NOTE: git5 is incorrect, it should be git) $ cd bpi-tools

$ sudo ./bpi.tools -u -U Step 3: Use bpi-update to update kerenl $ mkdir update_file $ cd update_file $ sudo bpi-update -c bpi-m3.conf (NOTE: THERE IS NO ov5640 driver in update in bpi-tools) $ sudo reboot

The Kernel did not upgrade.

This is what I have: uname -a Linux bpi-iot-ros-ai 3.4.39-BPI-M3-Kernel #1 SMP PREEMPT Fri Nov 3 01:03:00 UTC 2017 armv7l armv7l armv7l GNU/Linux

ls update_file/ 3.4.39-BPI-M3-Kernel.tgz bpi-m3-ov8865.conf camera.tgz addons.tgz bpi-service.tgz libvdpau_sunxi.tgz BOOTLOADER-bpi-m3.tgz bpi-tools.tgz ov5640 BPI-BOOT-bpi-m3-ov8865.tgz brcm.tgz ov8865-enable.tgz BPI-BOOT-bpi-m3.tgz bt.tgz ov8865.tgz bpi-m3.conf camera-apps.tgz

I am not sure if it is the driver issue or the camera (ov5640) board is incorrect. I saw in the BPI-M3 schematics CSI-PWDN-F is connected to PD15 pin of A83T, while in the A83T_TABLET_STD_V1_2 schematics CSI-PWDN-F is connected to PE19.

Tried to contact Nora.Lee but she is not helpful, although she showed the video of ov5640.
