I am trying to get USB 2.0 port to reach maximum bandwidth with OTG port (Hi-Speed - 480 MegaBits/second) on PineCube device. Currently it is performing as Full-Speed (12.5 MegaBytes/second) usb port.

I have measured the speed and performance using iperf + g_ether kernel mod + OTG port (details below)

Official datasheet of PineCube (https://files.pine64.org/doc/datasheet/p...180123.pdf) tells that the port can perform up to 60 MegaBytes/second or 480 MegaBits/second.

UVC gadget (g_webcam module) is also performing at Full-Speed mode.

My questions are:

How can i reach high speed on USB 2.0 port. (probably too general)
Could the issue be be related to USB drivers or Device Tree set up?

For a client project I have obtained two PineCube units and have tried to set them up with Armbian, but regardless of the SBC I see the same issue. After starting a download of a larger (multiple MB) file from a HTTPS server (Git repository), the system becomes unresponsive and has to be hard reset.

* I used two different PineCube units.
* I used a known good SD card (pulled from a working Raspberry Pi 3B system).
* I used different USB cables and chargers (also used with Raspberry Pi & Odroid systems previously).
* I used Ethernet and WiFi (separately) with identical results.
* I used the Focal Armbian version, then the Buster version, with identical results.

Does anyone have stable Ethernet/WiFi on PineCube with Armbian, or is this considered to be an unstable feature? The PineCube wiki seems to hint at this being still experimental.]]>

Just registered for the forum, but I’ve dancing around the Pine-world for some time (even have an OG Pine64 SBC I got from the first Kickstarter laying around somewhere...).

I saw that the Pinecil was released & while I don’t *need* another soldering iron I had always wanted to check out a TS80/100, but couldn’t justify the price (once I decided I needed something decent I got a Metcal SP-200 in very good condition for $70 + a couple tips. It’s no MX-5000, but gets the job done quite nicely for about as much as the aforementioned Chinese irons!). I dig a lot about the Pinecil & the low cost, USB-PD & other bits means I could find a use for it. So I figured I might as well consider all the Pine offerings if I am to buy some Pine kit and then I saw the PineCube & intrigued I became Smile

Long story short - the wiki says that currently ‘we don’t know how to use the hw encoder yet’. Doing a quick Google I saw that there are a couple GitHub projects making use of the S3 chips hw encoder (from an OrangePi) running Armbian & have basic examples that include using it to encode a live camera stream.

I’ll probably scoop one regardless if for no other reason than to toy around with/possibly use as a 3D printer cam, but figured I’d throw this out there in the off chance that no one had checked the existing projects for something that might be a drop-in:

https://github.com/rosimildo/videoenc (There are others, this seemed to be one of the more recent ones).

I managed to create a buildroot image with kernel 5.10rc4 for the pinecube. The actually usb-patch from daniel fullmer is not yet included.

ffmpeg and v4l2 are preinstalled in the image. I add the link to download the image here (google drive). Simply burn to sdcard.

The image boots on the console UART2. An ethernet connection is done via dhcp and sshd starts automatically.

Login is root & Password pinecube.

Unfortunately Wifi is not working yet. Also media-ctl brings an error "no /dev/media0".

I am grateful for tips on further configuration of the kernel and necessary packages.

I start ffmpeg this way:

Code:
ffmpeg -listen 1 -i rtmp://localhost:1935/live/cube -c copy  rtmp://localhost:1935/live/mpv

As a result, ffmpeg is hangig as if it was listening on the socket. But when I check the sockets (e.g. with ss -a), port 1935 is not displayed.

When I try to stream from the pinecube, with this command:

Code:
[root@nixos:/home/nixos]# ffmpeg -s 640x480 -r 15 -i /dev/video0 -vcodec flv -f flv rtmp://pbp:1935/live/cube

I get this error:

Code:
[tcp @ 0x81110] Connection to tcp://pbp:1935 failed: Connection refused

[rtmp @ 0x80c10] Cannot open connection tcp://pbp:1935

rtmp://pbp:1935/live/cube: Connection refused

Code:
ffmpeg -listen 1 -i rtmp://localhost:1935/live/cube -c copy  rtmp://localhost:1935/live/mpv

Code:
[root@nixos:/home/nixos]# ffmpeg -s 640x480 -r 15 -i /dev/video0 -vcodec flv -f flv rtmp://pbp:1935/live/cube

I get this error:

Code:
[tcp @ 0x81110] Connection to tcp://pbp:1935 failed: Connection refused

[rtmp @ 0x80c10] Cannot open connection tcp://pbp:1935

rtmp://pbp:1935/live/cube: Connection refused

which can be expected, as there is nothing listening on port 1935 on pbp.

Has anybody got ffmpeg working as a rtmp server or are you using nginx with rtmp support enabled?
Are there other lightweight streaming servers availabe?

at Elimo Engineering we have designed Impetus, a SoM that shares the Allwinner S3 SoC with the PineCube. Our first supported platform is (going to be) Buildroot.

Given the similarities of the two, and the general lack of support for the S3, we have decided to do double purpose and integrate support for the PineCube into Buildroot.

You can find the repo on our GitHub account and build instructions in the board support directory readme.

The most important thing that this provides is support for the S3's DDR3 in u-boot. Unfortunately mainline u-boot does not have that yet.

Since we don't have a PineCube ourselves, this is unfortunately untested, but it should get a functional system that boots to a console on UART0. It's pretty fast too, getting there in 1.5 seconds from u-boot to login prompt.

All in all, I think this could be a good starting point for further development.]]>
