Well, that's pretty much what "providing SDK to vendors to customize their devices" means; if you're not planning to buy SOCs to make large quantities of custom devices, you're not a vendor for whom the manufacturer cares to provide an SDK.

Allwinner isn't the only vendor guilty of that. Ever try finding a datasheet for any Broadcom or Qualcomm part? I'm not defending the practice. I wish all SOC vendors would give full access to any/all documentation. They can still have a policy of "no support unless you sign a contract to buy X number of parts."

This chip looks similar to the F1C100s that was used in the $3 Linux business card: https://www.thirtythreeforty.net/posts/2019/12/my-business-c... By switching to RISC-V I guess Allwinner can save a few cents of Arm license fees.

Might be that they care about open computers.

Check out the history of Allwinner and open source and get back to us.

Allwinner? Maybe, but I highly doubt it. They're one of the worst offenders when it comes to releasing sources.[0] [0] https://linux-sunxi.org/GPL_Violations

Allwinner wants to sell as many SoCs as possible. Being open and having good Linux support is good business. The serve the low-end sector, which means they may not spend a lot of money for Linux support. But Linux support is good for business.

Giant company willfully violates the rules, and when someone tries to make them follow the rules, the poor, poor little giant company is "blackmailed" and it shouldn't have been done because they're "located in China". Or something.

This is why we can't have nice things.

The second paragraph says: > Besides the built-in RAM, Allwinner D1s comes with many of the same features as D1 RISC-V SoC, but loses HDMI output and the HiFi 4 audio DSP, and Allwinner made some tweaks to the IOs with one less I2S audio interface, and general-purpose ADC.

Were the HDMI output and audio DSP licensed IP blocks from another company? On other Allwinner chips, the HDMI phy is from a different company than Allwinner. Guess this is a super budget respin of this chip, where most licensed IP blocks have been removed.

HIFI4 is Cadence IP.

I'm not entirely sure what you mean by this. Companies in certain areas shouldnt have to follow the same rules as the rest of us? The GPL doesn't mention any geographical areas where it doesn't apply

agreed Broadcom worst company , never seen Raspberry Pi full CPU register details

As a practical matter the rule of law in China is more or less nonexistent.
