Is the isp1 Driver included? rk gstreamer with dual camera supported? It's up2date with FriendlyARM sources which means its there ... but untested since I don't have any cameras. I can confirm that: - driver rkisp1 and both ISP's (at 0xFF9 1 000 and 0XFF9 2 00 address ) present; - no /dev/videoX de...
So instead of replying to the question you play with words.. Correct question - is 50% of correct answer. I highly recommend you to follow IgorP suggestion to use Armbian, but you also can try avafinger version of Ubuntu - it's even smaller, than Armbian (and contain less packages - around 200MB co...
Still no working dual camera support even with the latest (20190625) version and I think I'm not the only one. The csi1 connected camera is extremely slow and distorted. Well, looks like it's working, but with stability issues. Take a time to look at 'dmseg' output - it may look like this errors - ...
I am building a NAS and I don't need video-related stuff. When I apt-update I always get tons of updates regarding mesa or libs or qt. I can't understand, why you think, for example, that Qt for WebAsm is not server only tech? Which is working via Mesa too. upd: it's not called a NAS distro. it's j...
Check a spec of your HDD - for 3.5" it's should be something like: "+12V/0.5A +5V/0.7A" and try to make a calculation with respect to conversion efficiency around 0.75. For this particular case (it's a spec from old SP1614C Samsung 3.5" HDD - so we will have 12V/1.78A for 2HDD) l...
do you have good enough power to maintain 2 USB drivers? (on writing they consume much more energy than on idle\reading)

It's included in distro as a GStreamer bash script - dual-camera.sh

3.5" HDD can have very different power requirements - and difference between HDD with 1 and 7 platters (and with 1 or 2 actuators, like some 14GB+) can be few times - so it's no general solution. http://wiki.friendlyarm.com/wiki/index.php/NanoPi_M4_SATA_HAT says exactly about 12V/4A and 5V/4A i...

please note, that this is device files for T4, M4 and Neo4 boards itself (and not a just revision of one file) and you need to use the correct one for your board.

How to correct? :roll: It's not clear a reason of issue on you system. I just leave few links, which can help you: - Original driver source - it's ARM web-site with user-space drivers - you may install it by hands (and need to enable ARM Mali in kernel too). - For Armbian exist a media script , whi...
probably, you need to install BIOS on this board before start to use it ;-)

Maybe something in filesystem, related to wi-fi, was corrupted - you may check with new system image. Also, Armbian use a slightly higher CPU frequency settings (2.0GHz for A72 cores instead 1.8) - and required more power (and cooling system too) - so it can be good idea to try to use another/more p...

It's self-explaining message - you try to use amd64(aka X86_64) package on arm64(aka aarch64).

You need to find a suitable package(with arm64 in name) to install on this board
Thanks for that. I think a lot of people on here would see a benefit of streaming dual mipi cameras via motion for example. There's a lot of potential for smoother video that we can utilise here for robotics and VR (and both for what I'm hoping to achieve). it's much more easy - use new build form ...

I'll check for a new camera. it's only two cameras, which works with T4\M4\Neo4 - one it's this 13MP without focus at all, second - cam400 - with manual focus, but it's 4MP wide-lens and with 16:9 sensor (very cool by itself, but camera don't support it high-speed modes :( ) or you need to used USB...

To use dual-camera mode kernel need to be build with "new" rkisp1 , while friendlyelec come with "old" rkisp10 (and armbian can be recompiled with "old" ISP too) - so only one camera in time can work. I am just return from vacation to continue evaluate this question, so...

Is there anyone who found an ov13850 driver supporting Autofocus Control ? why you think, that this camera support autofocus? OV 13850 Sensor doesn't, and looks like it's no optical system at all on top of the sensor(manual or automatic). PS: if you really interesting about another "driver&quo...

accelerated driver support EGL/OpenGL ES2, not a Desktop GLX/OpenGL.

try `eglinfo` and GL ES2 version of software, like `glmark2-es2` to use accelerated(ARM Mali) drivers.
it's looks like it's no official document for writing IQ file. you may find(and, probably, already did) some info in rockchip github repos, like a camera_engine_cifisp or camera_engine_rkisp, or kernel itself, but all that info required reverse-engineering.

It says only H3 suppprt , does this mean mjpg-streamer not work on M4 ?

if it says only H3 - probably, it's true

btw, H3 it's a AllWinner SoC, while NanoPi M4 use RockChip SoC. Just 2 different companies, different h\w & s\w support. (you need to add Asian way of thinking too)
not sure, that it supported by ISP
maybe some USB cameras with hardware MJPEG encoder.
More than that, i see that the partition file system s Other, but in other tool i see it ext3 and when i connect to the sd when it's running on it's machine i see that it's ext4. No, it's not. But software, which you try to use - not support ext4 correctly. Why you don't want just to follow instruc...
I think you gave me the hint, as i see the partition is ext4 partition. that's why i can't extend more. I will try to convert to FAT32 and will see if it will fix that. I'll update here You understand me wrong. Only fat16 have a limit for 4GB from what I remember. ext2/3/4 don't have a limit below ...
I tried doing that offline on my windows, it also didn't give me the option to increase the size. which is strange, is there any configuration of limiting partition size ? not for ext2/3/4 at size around 4GB(it's a fat16 limit). as I see from wiki , this board\distro don't have a automatic resizing...
I investigated more and more and seems that the partition is limited, do you have any idea if this is a realistic option? Did you try to resize partition on PC with card-reader? Did you try to use older distro(willy from 20180207)? Another option(which ) - to compile you own image - you can pre-sel...
you write to wrong place - that's a RockChip Rk3399 Linux, not a A64(I believe, it's a AllWinner - and thats a right place ) ;) so it's impossible to check exactly what happens with you disto/board ;) btw, by default, all disto's for Rk3399(and RPi, and many other boards) expand partition to full SD...
and is there a cheaper solution than the jetson nano that have hardware h.265 encoding ? it's hard to say - some of 96 boards , like Qualcomm 845/820 and Huawei Kirin 960\970 and Helio X20 have h265 encoder, but I am not sure about driver support (it's a big chance, that this is no drivers for Linu...
don't think - just measure temperature.
If you like to test s performance of SD-cards - it's a good idea to buy a SD-Card reader, not a single board computer :)
For Midgard GPU theoretical maximum is about 0.034*MHz*Core( see GFlops per core ), so for T860x4 at 800MHz it's about 108.8 GFlop, while at 200MHz it's only 27.2 GFlop. Since you get float4 : 45.23 | 46.33 on FireFly - it can't run on 200MHz even theoretically. Based on yours values from T4 - looks...
And we compared T4 benchmark with the Firefly-RK3399, it has same gflops on differents types, but enqueueMapBuffer and enqueueUnmap alot faster than T4, - what kernel use FireFly? (https://forum.armbian.com/topic/8097-nanopi-m4-performance-and-consumption-review/ here you can find a performance tab...
As I mention, it's a USB3 hub on M4 - so you shouldn't expect a full speed of USB3 from every port. A correct way to check USB3 - performance must be even higher, than theoretical maximum for USB2 - which is around 60MB\s for read\write. You may find more information on performance thread (but with ...
it's active by default (otherwise non of USB ports will work - since they connected via a USB3 hub to Rk3399).
it's called MCAM400 - you can find it here https://www.friendlyarm.com/index.php?route=product/product&path=78&product_id=247 PS: please note, support limited in NanoPI boards only to 1 camera in time via GStreamer only(V4L can be used only with NV12 format) and only to basic resolutions (li...

You need to be sure, that you build OpenCV with Video4Linux2 (V4L) support - if you want to use this API.
do you know any other Affordable alternatives yesterday was announced Nvidia Jetson nano - it's simplified version of older TX1 in smaller small factor and 99$ price - support encoding h265/265 4k@30fps or multiply 1080p@60/30fps - more detailed [code=https://devblogs.nvidia.com/jetson-nano-ai-comp...
