I wish I am able to get paid support but unfortunately I am not there yet. Yet I am happy to know the cost of getting a paid support for me just in case. I tried mainline latest image, with it bluetooth and camera (CAM500B) are not working so its long shot. Certainly I will upgrade in next few months. Could you please point me the label in GIT for the "5.30 stable Debian GNU/Linux 8 (jessie) 3.4.113-sun8i" so I will try to rebuild with the eMMC fix.

That should be it... I didn't build from source. I downloaded 5.30 legacy image and only that version able to expose bluetooth HCI0. I downloaded latest legacy 5.37 which is not supporting bluetooth yet it is able to detect eMMC. Appreciate if you can point to fix the Bluetooth on 5.37 legacy kernel Image.

I can confirm that latest image can detect the eMMC and nand-sata-install works fine. Is there any thing I can do to make the legacy image working. I do not have resources to upgrade and test all software with mainline kernel for now.

Yes this version is working fine. Only newly ordered boards are failing.

Below is the new NANO-PI NEO/AIR PCB https://drive.google.com/open?id=0B8f669v6HDOxMW1qbFZsNkt0emU2dFVtU0VLYzFXVE1NN2JZ I will try latest kernel today and let you know. Regardless I need to make it working in this legacy kernel as I cant upgrade all software for main line kernel yet.

Thank you. I do not see mmcblk1 in my /dev or /sys/class/block directories. eMMC is booting with default Allwinner Linux OS, based on that I guess eMMC is working. Please give me some details on how to access emmc from os if its not visible from OS /dev directory.

Apologies :-) Here is the link from the command output http://sprunge.us/MnEmZo

I am using legacy kernel 3.4.113 with Nano-PI NEO/AIR. Up until recently every thing is fine. With NEO/AIR new boards nand-sata-install script is failing with "There is no targets". Unfortunately it is lot of work to upgrade the kernel to mainline at this stage. I greatly appreciate if anyone share the steps to fix this issue for this kernel.

Any solution for this. I am having same issue.

@Igor @Lex using cap_v4l2, I am able to get 2592X1936 " 7.5 fps :-) fswebcam is limiting to 800X600. guvcview is not working. (no still image , video files is black) I am wokring on porting cap_v4l2 to my openCV java binding to connect to app. I will run a field test to see the prformance and let you guys know :-) Thanks

Thaks for input @lex first time compiling Linux driver.. java guy here :-) I wget ov5640.c into /usr/src/linux-headers-3.4.112-sun8i/drivers/media/video/sunxi-vfe/device/ and ran make cmd from linux-headers-3.4.112-sun8i/ directory. root@nanopiair:/usr/src/linux-headers-3.4.112-sun8i# export CC=gcc root@nanopiair:/usr/src/linux-headers-3.4.112-sun8i# make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j2 INSTALL_MOD_PATH=output SUBDIRS=drivers/media/video/sunxi-vfe/device modules make[1]: *** No rule to make target 'drivers/media/video/sunxi-vfe/device/ov2640.c', needed by 'drivers/media/video/sunxi-vfe/device/ov2640.o'.

Could you please point me the latest ov5640.c and makefile for armbian? I may try to figure out if I can compile the driver.

Below is the boot log @qualcomm.com>

OK, I suppose "avafinger" driver is targeting android. So I am trying to take allwinner's https://github.com/allwinner-ics/lichee_linux-3.0/blob/master/drivers/media/video/sun4i_csi/device/ov5640.c and do a merger with "avafinger" version to leverage his efforts. I am using https://cdn.sparkfun.com/datasheets/Sensors/LightImaging/OV5640_datasheet.pdffor understanding register values. Appreciate any suggestions to get this working. Please let me know if anybody already drove through this stuff :-)

Hi, I changed fex file as recommended and I see no issues in dmesg. The camera is recognized and here is the v4l2 output. I compiled and able to use https://github.com/avafinger/fswebcam. happy to see I have good exposure control. https://drive.google.com/open?id=0B-dDl4KN9nbdbVZwa2hhY29TLU0 Exposure range seems 0 - 5. I am only able to get max 800X600 resolution with default armbian ov5640 driver. My aim is to get control of exposure and frame-rate. As per https://github.com/avafinger/ov5640/tree/Armbian_H3I should be able to control frame rate as module params. So I am started comipleing drivier but i didnt see any make file in the project. So I added simple make file as blow obj-m += ov5640.o all: make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules clean: make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean make command returned errors make -C /lib/modules/3.4.112-sun8i/build M=/root/ov5640 modules make[1]: Entering directory '/usr/src/linux-headers-3.4.112-sun8i' CC [M] /root/ov5640/ov5640.o /root/ov5640/ov5640.c:18:20: fatal error: camera.h: No such file or directory #include "camera.h" ^ compilation terminated. scripts/Makefile.build:313: recipe for target '/root/ov5640/ov5640.o' failed make[2]: *** [/root/ov5640/ov5640.o] Error 1 Makefile:1368: recipe for target '_module_/root/ov5640' failed make[1]: *** [_module_/root/ov5640] Error 2 make[1]: Leaving directory '/usr/src/linux-headers-3.4.112-sun8i' Makefile:5: recipe for target 'all' failed make: *** [all] Error 2 I am trying to work this cam with openCV. I used ELP 5MP usb camera with opencv before but I couldn't get control over frame-rate as that's hard coded in their UVC drivers. So I guess if I can get this ov5640 driver I may have an opportunity to good control through my app. I am doing an opencv image processing project. I appriciate any help on compiling this driver. Thanks

Hi, Thanks for that. I did below steps 1. cd /boot 2. bin2fex script.bin script.fex 3. Updated the [csi0] section with above fex config 4. fex2bin script.fex script.bin 5. nano /etc/modules-load/modules.conf 6. added ov5640 and vfe_v4l2 after reboot, I am able to see /dev/video0 and VFE seems ok but there are issues in CSI-0 pins and stuff. Below is the dmesg output. I installed v4l2-utils and fswebcam. wsfebcam output giving below error. --- Opening /dev/video0... Trying source module v4l2... /dev/video0 opened. No input was specified, using the first. Unable to query input 0. VIDIOC_ENUMINPUT: Invalid argument Thanks Sri

Hi, I am using Armbian for NanoPI NEO AIR + CAM500B. I am unable to see any /dev/video0. I am able to get the camera working with FA default image. Here is my dmeg output. I really appreciate any help to get this working. I would like to use OV5640 with https://github.com/avafinger/ov5640driversto control frame rate. Thanks
