dmorse Posted July 20, 2017 Share Posted July 20, 2017 This is on a fresh build of Armbian from source. I'm not seeing the camera appearing in /dev/video0, as you would expect. I've tried the solution that @sri suggested on this thread https://forum.armbian.com/index.php?/topic/3225-nanopi-neo-air-cam500b-issue/ but the device is still not visible. Here is the contents of my /etc/modules file #w1-sunxi #w1-gpio #w1-therm sunxi-cir hci_uart rfcomm hidp dhd g_serial ov5640 vfe_v4l2 And here is the output from dmesg [ 0.000000] Booting Linux on physical CPU 0 [ 0.000000] Initializing cgroup subsys cpuset [ 0.000000] Initializing cgroup subsys cpu [ 0.000000] Linux version 3.4.113-sun8i (root@crosscompile) (gcc version 5.4.0 20160609 (Ubuntu/Linaro 5.4.0-6ubuntu1~16.04.4) ) #10 SMP PREEMPT Thu Jul 20 11:40:34 BST 2017 [ 0.000000] CPU: ARMv7 Processor [410fc075] revision 5 (ARMv7), cr=10c5387d [ 0.000000] CPU: PIPT / VIPT nonaliasing data cache, VIPT aliasing instruction cache [ 0.000000] Machine: sun8i [ 0.000000] cma: CMA: reserved 160 MiB at 56000000 [ 0.000000] Memory policy: ECC disabled, Data cache writealloc [ 0.000000] On node 0 totalpages: 131072 [ 0.000000] free_area_init_node: node 0, pgdat c0a7b900, node_mem_map c0c01000 [ 0.000000] Normal zone: 1152 pages used for memmap [ 0.000000] Normal zone: 0 pages reserved [ 0.000000] Normal zone: 129920 pages, LIFO batch:31 [ 0.000000] script_init enter!

Have i forgot to include somethign when compiling the kernel? The aim of all of this is to get a build where I can control the focus of the camera. Teh standard build offered my friendlyarm will run the camera, but I can't control the focus with those builds. Link to comment Share on other sites More sharing options...
@lex Posted July 29, 2017 Share Posted July 29, 2017 Edit your script.bin and check if you have i2c available for the CSI, something like: Spoiler [twi2] twi_used = 0 twi_start()434 - [i2c0] START can't sendout! Is an indication of i2c is in use by something else. Edit: maybe u-boot related? Link to comment Share on other sites More sharing options...
dmorse Posted July 31, 2017 Author Share Posted July 31, 2017 Yep, already have twi_used=0 for twi2. Or were you saying to turn it on? Digging around the kernel and putting various debug statements in various places, I have been able to trace it down to this section of the bsp_clie.c file with a switch on frame_info->pix_ch_fmt[ch] inside the for loop case PIX_FMT_YUYV: if(bus_pix_type[ch] == BUS_FMT_YUYV) { fmt_cfg[ch].input_fmt = CSI_RAW; fmt_cfg[ch].output_fmt = (is_buf_itl[ch] == 1)? CSI_FRAME_RAW_8:CSI_FIELD_RAW_8; } else { printk(KERN_CRIT "[DGM] bsp_csi_set_fmt Failed on frame_info->ch_field (PIX_FMT_YUYV) idx: %d; bus_pix_type 0x%x; case 0x%x, bus_info->bus_ch_fmt 0x%x\n", ch, bus_pix_type[ch], PIX_FMT_YUYV, bus_info->bus_ch_fmt[ch]); return -1; } break; Tracing this back up into the vfe.c file, it looks as if frame_info->pix_ch_fmt[ch] is getting set based on a called to pix_fmt_v4l2_to_common() and the bus_pix_type[ch] comes from find_bus_type(), and the value that gets passed into that comes from bus_pix_code_v4l2_to_common() (and has a value of 0x2006, or BUS_FMT_UYVY8_2x8). I've grabbed the vfe.c and the ov5640.c files from the lichee kernel and put those into my armbian source tree before building and that does seem to get me past this issue, but I now have problems when trying to map the memory for the buffers.

dmorse Posted July 31, 2017 Author Share Posted July 31, 2017 Should have clarified, I can now see the device and I can capture images off it using this program https://github.com/avafinger/cap-v4l2 However I am still having issues when running this one: https://github.com/jacksonliam/mjpg-streamer I've traced the errors through the kernel and I have hit the block of code mentioned above.
