Allwinner D1 RISC-V processor SDK & Documentation

We published information about Allwinner D1 SBC and processor a few weeks ago. The news was pretty interesting as it’s the first RISC-V processor from the company, and one of the first affordable RISC-V SBC.

But all we had at the time was hardware information from a leak, or rather from China-only Allwinner developer website. But now the company has added more information to its open-source development website with the release of documentation, now only in Chinese, as well as the Allwinner D1 Tina SDK.

Eventually, there should be a better SDK via linux-sunxi community and some are already working on the Allwinner D1 SBC, but let’s try to get the SDK from Allwinner and build the code from source using the documentation.

First, you’d need to register on Allwinner open-source website and click on signup.

You’ll probably want to select Email registration. Now fill your username, select a country, enter a company name, password, and email. For the country, anything is probably OK, but I’d avoid the default (China) just in case it sets the interface in Chinese. That is unless you can read Chinese of course!

Now click on the blue button next to the verification code field, and you should receive an email with the code. Now accept the terms and conditions (in Chinese only), and tick or untick the last line to receive information (or not) from Quan Zhi (aka Allwinner).

We now have access to several SDK’s and documentation, but the one that interests us here is D1_Tina_Open. We can click on the “SDK” text and then download it. At this point, we are presented with a disclaimer saying that whatever happens is not Allwinner’s responsibility, and you’d have to handle the license for any third-party code yourself.

I agreed, and got the following basic instructions:

I’ve then clicked on “Create a public key”, and insert the public key from my Ubuntu 20.04 laptop to get access to Allwinner repositories.

We should not install the repo boot script from the command as follows:

then edit repo/repo to change to the ssh username, e.g. to cnxsoft

Optionally copy the binary to your path and change the permissions:
