cam

I had to resolder the pins of the debug port on my NanoPi NEO Air and must have damaged the RX connection as I am unable to send commands but can receive read the debug output fine. Is it possible to change the debug port to UART1 or create another root terminal at another serial port?

Thanks for your reply! I double checked I definitely have the cam500b. This is the output of: dmesg|grep 5640 & dmesg|grep csi root@nanopiair:~# dmesg|grep 5640 & dmesg|grep csi [1] 1425 [ 8.895031] ov5640 0-003c: Linked as a consumer to regulator.5 [ 8.895101] ov5640 0-003c: Linked as a consumer to regulator.6 [ 8.895156] ov5640 0-003c: Linked as a consumer to regulator.4 [1]+ Done dmesg | grep --color=auto 5640 It looks like the ov5640 driver has loaded but not the CSI?

I haven't had any luck getting the ov5640 camera module working with the nanopi air. I have compiled the latest dev version of bionic and enabled the ov5640 as a module in menuconfig. I currently cannot get it showing up under /dev/video* Any ideas?

Hi All, I am having issues reading frames from a usb camera connected to my nanopi neo air. I can get images from a logitech C170 webcam fine but not from this other USB camera module. I can access it from my mac/ubuntu VM fine so it definitely works. The device is recognised as a video device and mounts to /dev/video0 but times out when I try to get frames from it. It seems like a driver issue but I can't figure it out. Here is the dmesg output after I plug it in: [Nov 1 06:27] usb 8-1: USB disconnect, device number 6 [ +2.029724] usb 5-1: new high-speed USB device number 22 using ehci-platform [ +0.160076] usb 5-1: device descriptor read/64, error -71 [ +0.280002] usb 5-1: device descriptor read/64, error -71 [ +0.270029] usb 5-1: new high-speed USB device number 23 using ehci-platform [ +0.379982] usb 5-1: device descriptor read/64, error -71 [ +0.279977] usb 5-1: device descriptor read/64, error -71 [ +0.120166] usb usb5-port1: attempt power cycle [ +0.489866] usb 5-1: new high-speed USB device number 24 using ehci-platform [ +0.439988] usb 5-1: device not accepting address 24, error -71 [ +0.149994] usb 5-1: new high-speed USB device number 25 using ehci-platform [ +0.440043] usb 5-1: device not accepting address 25, error -71 [ +0.000245] usb usb5-port1: unable to enumerate USB device [ +0.479723] usb 8-1: new full-speed USB device number 7 using ohci-platform [ +0.263076] usb 8-1: not running at top speed; connect to a high speed hub [ +0.023017] usb 8-1: New USB device found, idVendor=0c45, idProduct=6366 [ +0.000036] usb 8-1: New USB device strings: Mfr=2, Product=1, SerialNumber=3 [ +0.000022] usb 8-1: Product: HD USB Camera [ +0.000023] usb 8-1: Manufacturer: HD USB Manufacturer [ +0.000022] usb 8-1: SerialNumber: SN0001 [ +0.008121] uvcvideo: Found UVC 1.00 device HD USB Camera (0c45:6366) [ +0.027655] uvcvideo 8-1:1.0: Entity type for entity Extension 4 was not initialized!

What did you do to get them working?

How can I check that my board has this patch applied? I installed a fresh image of bionic on my NeoAir a week ago and am also having the same issue with the camera module. It is not being recognised as a video device

Has anyone had any success with installing numpy on the NanoPi Neo Air? Installing via pip install numpy -v it hangs at these same lines every time: arm-linux-gnueabihf-gcc: numpy/linalg/lapack_litemodule.c arm-linux-gnueabihf-gcc: numpy/linalg/lapack_lite/python_xerbla.c arm-linux-gnueabihf-gcc: numpy/linalg/lapack_lite/f2c_z_lapack.c arm-linux-gnueabihf-gcc: numpy/linalg/lapack_lite/f2c_c_lapack.c arm-linux-gnueabihf-gcc: numpy/linalg/lapack_lite/f2c_d_lapack.c arm-linux-gnueabihf-gcc: numpy/linalg/lapack_lite/f2c_s_lapack.c I am unable to get a response from the serial terminal or ssh into the device whilst it hangs here. I'm currently using Armbian Ubuntu 18.04.
