Allwinner V831 SDK about libmaix HOT 20 OPEN

Closed SDK makes the V831 a fairly worthless chip, probably only a couple of companies will use it. I had low confidence they'd get the NPU working anyway.

The RV1126 and RV1109 SDK are the same SDK, you can download the SDK using the Firefly link. It is just two different compile options. Based on the V831 news we'll put our main effort in to the RV1109. We have built and tested the SDK on the RV1109 -- it builds and works. We have started porting our app. I haven't found anyone shipping RV1126 boards, no chips?

Sorry, Allwinner tell us we can't open V831 SDK, so we can't put V831 SDK on github like lindenis..... but 1126's SDK will be open

from libmaix.

Right the V831's NPU SDK now is pretty poor! RV1109 and 1126 is better if no price limitation, and Sipeed will start selling RV1126/RV1109 dev board and in stock

You can download a SDK for the SoC (Allwinner V831) from http://www.sochip.com.cn/v831/index.php?title=Downloading_the_Source

That won't work unless you buy the board from sochip ($500) and then they enter your public key on their side.

I am also interested, I have an IP camera that uses an AllWinner chip and an SP2305 MIPI-CSI camera.
I would just like to access the camera image, but I can't find any information about it. sipeed-maix-ii uses the same camera.

Hi @ar055 ,

I managed using libmax's pre-compiled libs. for some reason the libraries I had compiled (from Lindenis_V5) did not work on my camera.

I started the project, and had excellent results

I've mailed them and they replied me.
But how can I use those to get the.SDK from [email protected]?

from libmaix.

put them into .ssh like this....
jonsmirl@ares:~/.ssh$ ls
id_rsa id_rsa.pub

then git should work.

It should not ask for a password if everything is set up right.
$ cd ~/workspace
$ repo init -u [email protected]:V831_IPC/manifest.git -b master -m sc1670v_ipc_remote.xml
$ repo sync

Did you send sochip your id_rsa.pub and they added it on their side?

from libmaix.

You should not need a username and password. They have not added my id_rsa.pub so I get a prompt...
But if they had added my id_rsa.pub I won't get a prompt and it will work without a password.

You can practice with this on github, it works the same way. Make a project and try to access it with the git protocol. You won't be able to access it until your load your id_rsa.pub via the web interface into your account.

Can you confirm that

• RV1126 boards are coming
• RV1126 will use the same TinaLinux base installation with only a change to the libmaix libraries.
• RV1126 will be able to use the same ML models

from libmaix.

There is much RV1109/26 info here:
https://wiki.t-firefly.com/en/CAM-C11262U/hardware.html

RK1126 is not TinaLinux based, that is Allwinner - these are Rockchip.

Rockchip source code here:

The money and time I've wasted on trying bad options are much more than any price difference. In the end I'm buying $400 dev boards to get around your black box. The whole thing is another example of how you don't do the first thing about taking care of your customers. I only have one single reason to continue with anything from Sipeed: "I haven't found any alternative"

Rockchip is only marginally better. I have to get source code from random sources, half behind the Chinese firewall. The whole rockchip-linux is seriously different from the original u-boot/linux source, which actually has a chance of being vetted. I'm seriously considering going with an alternative that costs 5x.

Much of the Rockchip source code is here...
https://github.com/rockchip-linux

Not everything, but a lot of it.

Rockchip is standard u-boot, kernel, buildroot setup. Google helps Rockchip a lot since Google uses their chips in various products.
