I updated to kernel 5.4.43 but the module was still not available. A fresh install of the latest bionic image with kernel 5.4.43 is working. Camera driver loads at startup and I can take videos (at least at 640x480) with GStreamer Many thanks!

Thanks. I unloaded cedrus but the problem is still present. Indeed, the OV5640 driver isn't loaded. I expected the camera will work plug&play because the /dev/video0 device is present. But the device is also there without a connected camera. Looks like the driver isn't part of the current kernel (5.4.35-sunxi) because modprobe lists only "ov2680 ov2685 ov5645 ov5647 ov5675 ov5695 ov7251 ov772x ov7740 ov8856 ov9640"?

Hi, I'm want to use my old Nanopi Neo Air with CAM500B as wifi webcam. I flashed the latest armbian bionic image, installed v4l-utils and tried to list the cameras properties with `v4l2-compliance` and `v4l2-ctl --all` but the tools always crash and I can't kill them. `dmesg` shows a NULL pointer exception: [ 56.994526] 8<--- cut here --- [ 56.997657] Unable to handle kernel NULL pointer dereference at virtual address 00000068 [ 57.005825] pgd = c774af94 [ 57.008606] [00000068] *pgd=00000000 [ 57.012243] Internal error: Oops: 5 [#1] SMP THUMB2 [ 57.017122] Modules linked in: brcmfmac brcmutil sun8i_codec_analog sun8i_adda_pr_regmap sun4i_i2s snd_soc_simple_card snd_soc_simple_card_utils snd_soc_core lima snd_pcm_dmaengine gpu_sched sun4i_gpadc_iio snd_pcm cfg80211 snd_timer industrialio snd soundcore rfkill sun8i_thermal zram sunxi_cedrus(C) v4l2_mem2mem uio_pdrv_genirq uio cpufreq_dt sch_fq_codel usb_f_acm u_serial g_serial libcomposite ip_tables x_tables pwrseq_simple [ 57.055242] CPU: 1 PID: 2012 Comm: v4l2-compliance Tainted: G C 5.4.35-sunxi #trunk [ 57.064192] Hardware name: Allwinner sun8i Family [ 57.068916] PC is at v4l2_g_parm_cap+0x3c/0xb4 [ 57.073363] LR is at v4l2_g_parm_cap+0x27/0xb4 [ 57.077808] pc : [<c0796c04>] lr : [<c0796bef>] psr: 00030033 [ 57.084072] sp : d43d1d50 ip : d43d1d84 fp : d4e74840 [ 57.089296] r10: c0ab69f0 r9 : c0aaf59c r8 : d4f9d100 [ 57.094521] r7 : d70fd328 r6 : 00000000 r5 : d4ef6000 r4 : c0f04f48 [ 57.101100] r3 : 00000080 r2 : fffffff0 r1 : 00000000 r0 : d43d1d54 [ 57.107618] Flags: nzcv IRQs on FIQs on Mode SVC_32 ISA Thumb Segment none [ 57.114913] Control: 50c5387d Table: 54dbc06a DAC: 00000051 [ 57.120652] Process v4l2-compliance (pid: 2012, stack limit = 0x7ede4d8a) [ 57.127429] Stack: (0xd43d1d50 to 0xd43d2000) [ 57.131780] 1d40: 00000002 00000000 00000000 00000000 [ 57.139945] 1d60: 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 [ 57.148110] 1d80: 00000000 6a7c03d8 c104e334 c0f04f48 d4ef6000 d4e74840 c0ab69f0 c078a355 [ 57.156274] 1da0: c07b2311 d43d1e54 00000000 6a7c03d8 c0cc5604 d70fd328 c0cc5615 c078a31d [ 57.164440] 1dc0: c0f04f48 d70fd694 c0aaf59c c078af73 d73c0000 00000000 d4f9d100 00000000 [ 57.172605] 1de0: 00000000 d4ef6000 00000000 c0aaf59c c0f04f48 c023f9c5 00080040 c0ec5700 [ 57.180769] 1e00: 1f0be000 6a7c03d8 d7007c18 c0cc5615 c0f04f48 00000004 00000000 00000003 [ 57.188934] 1e20: 000000cc d4ef6000 d4ef6000 c078b41f c0f05400 bef96b8c d4e74840 c078adf5 [ 57.197098] 1e40: 00000000 00000000 00000000 00000000 c9bd4200 00000001 00000000 00000000 [ 57.205262] 1e60: 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 [ 57.213426] 1e80: 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 [ 57.221581] 1ea0: 00000000 d69bed78 00000001 00000000 00000001 d43d1ed0 00000004 c0f04f48 [ 57.229746] 1ec0: 60030013 c0150cc7 00000004 d43d1ed0 00000000 6a7c03d8 00000000 6a7c03d8 [ 57.237910] 1ee0: 00000000 c0f04f48 d4e74840 bef96b8c 00000003 bef96b8c d73d0ce8 c0262f41 [ 57.246075] 1f00: d4e2a240 00000002 d08fc7f8 d4e2a248 00000000 c0f04f48 00000000 00000000 [ 57.254239] 1f20: 00000000 00000000 00000000 6a7c03d8 5ac3c35a 00000002 d4e2a240 d08fc7f8 [ 57.262405] 1f40: d4e2a248 00000001 02364058 00000001 bef9705c c0253b5b 00000000 6a7c03d8 [ 57.270569] 1f60: c0f04f48 d4e74840 00000000 d4e74840 c0cc5615 bef96b8c 00000003 00000036 [ 57.278735] 1f80: bef9705c c02635d5 7123fc00 b6f34968 00000001 bef97060 00000036 c0101224 [ 57.286900] 1fa0: d43d0000 c0101001 b6f34968 00000001 00000003 c0cc5615 bef96b8c 7123fc00 [ 57.295064] 1fc0: b6f34968 00000001 bef97060 00000036 bef9a47c bef96a84 004c3e78 bef9705c [ 57.303229] 1fe0: 004c3f00 bef969b4 004845e7 b6d150a8 60030030 00000003 00000000 00000000 [ 57.311407] [<c0796c04>] (v4l2_g_parm_cap) from [<c078a355>] (v4l_g_parm+0x39/0x90) [ 57.319055] [<c078a355>] (v4l_g_parm) from [<c078af73>] (__video_do_ioctl+0x17f/0x314) [ 57.326963] [<c078af73>] (__video_do_ioctl) from [<c078b41f>] (video_usercopy+0x1ff/0x4bc) [ 57.335219] [<c078b41f>] (video_usercopy) from [<c0262f41>] (do_vfs_ioctl+0x8d/0x6e0) [ 57.343042] [<c0262f41>] (do_vfs_ioctl) from [<c02635d5>] (ksys_ioctl+0x41/0x58) [ 57.350431] [<c02635d5>] (ksys_ioctl) from [<c0101001>] (ret_fast_syscall+0x1/0x62) [ 57.358072] Exception stack(0xd43d1fa8 to 0xd43d1ff0) [ 57.363116] 1fa0: b6f34968 00000001 00000003 c0cc5615 bef96b8c 7123fc00 [ 57.371281] 1fc0: b6f34968 00000001 bef97060 00000036 bef9a47c bef96a84 004c3e78 bef9705c [ 57.379443] 1fe0: 004c3f00 bef969b4 004845e7 b6d150a8 [ 57.384491] Code: 01db bf44 2302 61ab (6eb3) 68db [ 57.389321] ---[ end trace b0284d13f94bede6 ]--- Is the camera broken or is this a driver problem?

Thanks, I donwloaded the 5.20 images from https://www.armbian.com/nanopi-neo-air/but now I found the current images at https://image.armbian.com/ and Armbian_5.24_Nanopiair_Ubuntu_xenial_3.4.113 is working without any problems. I installed it on my sd card and used nand-sata-install to copy the system to eMMC and it works with OTG support

Hi, I'm trying to install Armbian on my NanoPiAir. At first I booted in FEL mode and burned an image with Etcher to MMC. I tried Armbian_5.20_Nanopiair_Debian_jessie_3.4.112.img, Armbian_5.20_Nanopiair_Ubuntu_xenial_3.4.112.img and Armbian_5.24.161226_Nanopiair_Ubuntu_xenial_4.9.0.img. Then I removed the USB cable, removed the SD card and replugged the USB cable. With the 5.24 nightly build the blue LED startet flashing after some seconds. But there was no /dev/ttyACM0 device or usb device (I checked lsusb and dmesg) detected on my host computer (Linux Mint 17, 3.13.0-100). So I installed an image on my sd card with dd but the same problem. Then I soldered the UART pins and connected via screen /dev/ttyUSB0 which works without any problems. I started nand-sata-install script that finished with success. After removing my sd card I tried to start from eMMC but I only get this message via UART: U-Boot SPL 2016.09-armbian (Sep 15 2016 - 05:37:42) DRAM: 512 MiB Trying to boot from MMC2 MMC Device 1 not found spl: could not find mmc device. error: -19 SPL: failed to boot from all boot devices ### ERROR ### Please RESET the board ### I also tried to reflash the eMMC via FEL but etcher aborts everytime while flashing or after the verify process. Does this mean my eMMC is broken? Is there a way to check this?
