  1. The suggestion was to change to: powerdown-gpios = <&pio 4 15 1>; /* CSI-STBY-R: PE15 */ vfe_v4l2 is for legacy only. Can you set PG11 in u-boot and see if it works? I think is PD14, do it in u-boot cmd: gpio set PG11 gpio status PG11
  2. I don't have the board with me right now. But i still think i2c is not wired correctly. Perhaps someone else can measure and give the answer. Last thought: Try GPIO_ACTIVE_LOW if you have GPIO_ACTIVE_HIGH in your DTS
  3. Ouch, it is working then. The error is expected. In mainline you need to tell the sensor (csi) the format and size you want. Here is one example for streaming JPEG 1280x720: media-ctl --device /dev/media1 --set-v4l2 '"ov5640 1-003c":0[fmt:JPEG_1X8/1280x720]' For the mjpeg-streamer the fix is here: https://github.com/avafinger/bananapi-zero-ubuntu-base-minimal/issues/56 PS: I overlooked you output, i still think you wired the i2c1 and not i2c2
  4. Not sure i can give a good advice in this case, it is a bit confusing for me (software guy here). Looks like your sensor is detected with I2c-1 and it should be on i2c-2 , so i think it is the way you wired this module. PE12/CSI_SCK/TWI2_SCK --> CSI-SCK PE13/CSI_SDA/TWI2_SDA --> CSI-SDA and DOVDD, AVDD, DVDD should be in your DTS in the same way as Opi one. How you wired these pins to get the right voltage is a mystery to me.
  5. In order to use the imx219 sensor (or any other sensor) in mainline kernel 5.x you need to tell the sensor which format and size the sensor must deliver the frames using v4l2-ctl prior to grabbing the frames. Something like: v4l2-ctl --set-subdev-fmt pad=0,width=1280,height=960,code=0x3001 -d /dev/v4l-subdev1 v4l2-ctl --set-subdev-fmt pad=0,width=1280,height=960,code=0x3001 -d /dev/v4l-subdev0 v4l2-ctl --set-subdev-fmt pad=2,width=800,height=600,code=0x2008 -d /dev/v4l-subdev0 Collabora has a complete setup and a patched libcamera where you can pull some images
  6. You have the wrong pix_fmt. Try: -pix_fmt yuv420p Be aware you don't get HW encode with this version. Search the forum, someone already worked on the hw encoding side.
  7. I was an early backer of Pine64, it took so long to get my hands on one plus the learning curve in order to contribute with something useful, around 6 months, today things have evolved and 'this time' is an eternity. Not to mention the restriction to ship the battery from US. I just think they missed a great opportunity to create a kind of "convergence docker" that would export the gpios so you could drive other things, create an ecosystem around the device just like the Raspberry Pi has. The Makers should get this tip and launch a similar device and export all the pins. RK c
  8. Hi, I haven't follow the progress, but i like the Mobian w/ Phosh design, if you can report your findings would be great. Thanks. I have a few (noob?) question about the device and interfaces. * Would you know if it is possible to have access and use the UART to interface with some peripherals? I know there is an extension with HDMI, ethernet and USB. I don't mean USB to Serial. * Can you stick a barcode reader, or something similar like a proximity reader (if you have that extension)? * Last time i checked (was really long time ago) there was no
  9. That's why i asked. How would you wire the touch? I don't have OPI4 but i am curious where it should go to the OPI4. I am thinking to try it out on my NanoPi M4. And it would be interesting to know how to connect all these things, some wires do not show where it goes ... Make sure you have: &vopb { status = "okay"; }; &vopb_mmu { status = "okay"; }; &vopl { status = "okay"; }; &vopl_mmu { status = "okay"; };
  11. You can follow this thread and add the ov5640 overlay, use the ov5640 params from FE dts node.
  12. If you don't want to code, you could try this: https://www.claudiokuenzler.com/blog/999/kodi-tv-add-video-stream-ip-surveillance-camera-add-on
  13. Here are the instructions to run Htop remotely using a web browser. I often use Htop to monitor the health of my boards and servers (amd64). It is a good tool for the sys admin to monitor the servers in real-time without much resources and it is not very intrusive. Recipe 1 - Clone shellinabox root@cubieboard2:~# git clone https://github.com/shellinabox/shellinabox Cloning into 'shellinabox'... remote: Enumerating objects: 3073, done. remote: Total 3073 (delta 0), reused 0 (delta 0), pack-reused 3073 Receiving objects: 100% (3073/3073), 4.31 MiB |
  14. And the nice thing, you can have Htop in a Browser...
