Are you know that the Chinese comrades hav a clone of STM32 called GD32. I tested GD32F103C8 - didn't notice any problems.  :)

We should not be supporting piracy and IP violation, irrespective it is is made by comrades in China or comrades in the (former) Soviet Union. The Soviets pirated a lot of copyrighted chips made in the USA. The GD32 might work "the same" as the STM32 but no-one in their right mind would use it for a commercial, industrial or medical product. You'd get sued if you substituted one of these for the real thing and something went wrong, eg: early life failure, corner case issues, temperature issues etc. Besides, you have no come-back when something goes wrong and no support.

Full of bullshit as expected from you.

Where is the BS in that comment?

Also the author of this blog contacted ST about GD, and yea it looks like GD is not doing things by the book:

--- Quote ---Those GD32xxx devices are effectively a kind of clones of our STM32, but it's a pure piracy: no agreements of any kind between ST and Giga Device, no license... nothing. ST legal people are in charge of this problem.

They're too young to know and aware of that.

Making compatible products (i.e. reproducing same public external interfaces: like having a steering wheel) has absolutely nothing to do with piracy or IP violation.

Similarly, I could call you a murderer. Which you hopefully are not. Like Gigadevices are not pirates or IP violators.

There is also no proper ground over which you could get sued by using Gigadevices products. On the other hand, I can sue you over a murder. It's simple: get a lawyer to apply the paperwork. It's just not going to fly very well, unless there is a political reason for it to work.

AMD vs. Intel is a great analogy, really (there was Cyrix and others, as well). Try to understand it. And in the end, both have benefited from it; AMD has reproduced the Intel's interface, and later, Intel has reproduced the AMD's interface (AMD64) when it worked out better.

VK3DRB:
Remember the FTDI FT-232 chip debacle. Knock-offs were made in China at a fraction of the original cost. When FTDI did a strategic driver update for their chips, the fake chips ceased to work. That was smart but with one BIG exception. Through the supply chain, innocent purchasers of equipment using those knock-offs got their equipment bricked, which FTDI presumably failed to anticipate along with the backlash that followed. Piracy damages industry, stifle innovation and rips off the innovative inventors of technology. Ethical engineers will use the original devices that are still under patent protection and shun the "copy watch" brigade. Same with music and videos - unless it is public domain, piracy is theft. Even the egg-throwing badly-behaved Justin Bieber is entitled to the rewards of creating so-called intellectual or artistic property.

IMO, if functionality within the STN chip is protected by patents, and if the GD chip violates these patents, we should not be using them, even if STM supply is crippled due to a strike. But if no patents are violated, use the GD chip by all means, but of course at your risk.
