Power & Source of Big Ideas

In the specs it is stated "supports simultaneous input of dual camera data". I made my buy decision based on that. Well, me too :( Since this board made in communist China (and not at Republic of China(aka Taiwan) or mainly Chinese Singapore) - specs doesn't matter. Welcome to 1984 world ...

Did you get it working? Which compile settings do I have to make to get the isp1 driver compiled and loaded?
Thanks.

No. And it's no reason to make it work on current generation on FriendlyElec/Rk3399 hardware - since it's was designed without ability to work with dual cams.
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.

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)

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.

probably, you need to install BIOS on this board before start to use it ;-)

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 ...

try `eglinfo` and GL ES2 version of software, like `glmark2-es2` to use accelerated(ARM Mali) drivers.

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.

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 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?

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...

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?

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).

You need to be sure, that you build OpenCV with Video4Linux2 (V4L) support - if you want to use this API.
