kreston Posted December 5, 2019 Posted December 5, 2019 Armbianmonitor: http://ix.io/23BS Dear friends! Please help me! What am I doing wrong? I have Orange Pi Pc Plus. I am using Armbian. 4 months ago I bought a CSI camera OV5640 from Steven Zhao: https://www.aliexpress.com/item/32869355445.html With expansion board! It's working under Android, but /dev/video0 does not appear in Armbian! ~$ sudo uname -a Linux smart 3.4.113-sun8i #2 SMP PREEMPT Wed May 8 15:09:43 CEST 2019 armv7l armv7l armv7l GNU/Linux :~$ sudo modprobe ov5640 :~$ sudo modprobe vfe_v4l2 :~$ dmesg | grep -i ov56 [ 6555.158751] [OV5640@lex]init_sensor - frame_rate: 0, max_win_size: 11 [ 6563.092176] [OV5640@lex]CSI_SUBDEV_PWR_ON!

@lex Posted December 9, 2019 Posted December 9, 2019 If i recall correctly you need to set (enable) a pin on u-boot load time and specific to your PC Plus and OV5640. Have you tried to set the pin on u-boot boot.cmd? Something like: # OPI-PC camera (set PG11 for gc2035) gpio set PL10 gpio set PA17 #gpio set PG11 This error message typically tells you the board cannot find the attached sensor. Possible causes are: * Sensor Not powered correctly (see which pin or píns should be set at boot) Make sure theses lines are for the OV5640 and PC Plus. vip_dev0_power_en = port:PA17<1><default><default><1> vip_dev0_reset = port:PE14<1><default><default><1> vip_dev0_pwdn = port:PE15<1><default><default><0> * i2c is already in use, double check your Fex file and disable the correct twi, this seems to be OK in your FEX but try: [twi1] twi_used = 0 twi_scl = port:PA18<3><default><default><default> twi_sda = port:PA19<3><default><default><default> [twi2] twi_used = 0 twi_scl = port:PE12<3><default><default><default> twi_sda = port:PE13<3><default><default><default>
kreston Posted December 20, 2019 Author Posted December 20, 2019 Dear @@lex, I tried set different pin on u-boot boot.cmd... But this does not give a result ... dev/video0 does not appear! If i right understand, My board is Orange Pi PC Plus v 1.1. I don't know where can I to found number of board version! And I proceed from that is version 1.1... For my schematic PL10 look so: PL10/S_PWM/S_PL_EINT10 ---V2--->> PWR-LED According schematic: PE15 ----C5--->>CSI-STBY-EN But in my fex file: vip_dev0_pwdn = PE15<1><default><default><0> //may it be wrong??

Thank you very much!!!!! I don't know why, but dev/video0 does appeared!!!! And this is working!!! Yes! I'm happy !!! Now can I try opencv!!!! Thank @@lex too for help and answer!!!
kreston Posted December 21, 2019 Author Posted December 21, 2019 I captured video over vlc! It's working fine. I want to try translate video over ffmpeg. Dear friends! If someone know answers on my questions, please write here: 1) how to change fps and resolutions? only ffmpeg? can I to make it over hardware? 2) how to flip image of camera? I'm making simple robot for fun! And me need move camera with servo-motor. 3) how work AF? P.S. I don't know why, but I can't to use $fswebcam... There is error: "Error setting pixel format. VIDIOC_S_FMT: Operation not permitted."
Solution kreston Posted December 28, 2019 Author Solution Posted December 28, 2019 Guys! These are my actions for make CSI-camera OV-5640 on ORANGE PI PC PLUS work: 1) change fex-file vip_dev0_mname = "ov5640" vip_dev0_power_en = port:PA17<1><default><default><1> vip_dev0_reset = port:PE14<1><default><default><1> vip_dev0_pwdn = port:PE15<1><default><default><0> 2) Add next commands to /etc/rc.local sunxi-pio -m "PG11<1><0><1><1>" #DOVDD modprobe ov5640 modprobe vfe_v4l2 3) Add this to /boot/boot.cmd gpio set PG11 gpio set PA17 It's short way to the Purpose for Orange Pi Pc Plus with original 5Mp Ov5640 CSI camera from developer! This recipe can save someone a lot of time. P.S. It's working on legacy kernel! And I don't tried run it on others kernels... It's my system: ~$uname -a Linux smart 3.4.113-sun8i #2 SMP PREEMPT Wed May 8 15:09:43 CEST 2019 armv7l armv7l armv7l GNU/Linux P.P.S. Streaming video works well under ffmpeg, but has a 3-5 second delay! How it may be fixed - I don't know... May be someone know tool or way for make delay less, than 1 second??? I'm searching exit from this situation...
kreston Posted December 28, 2019 Author Posted December 28, 2019 I found the solution to make streaming without delay on 640x480: https://github.com/jacksonliam/mjpg-streamer It's working perfect! Delay is about 0.3 sec! 1
