淘宝有全套的SDK,非常详细(HDK&SDK),花点钱吧,不够一顿快餐的钱

@nothing, Is there Hi3516EV200 SDK in English, the versions I was able to find so far are in Chinese.

I got one board from zhenfanhei with  Hi3516EV200 , but when connect the USB in upload mode, it keeps reseting. Not sure what the issue might be ?

@OggyJFX , Quite agree with you regarding the jink Chinese products and the crook Chinese businessmen. Still the board was sent to me. As mentioned in the other forum topics, I was willing to give it for free, no one was interested. If you interested about it, I can ship it to you ?

As about Huawei, there are very serious concerns in Europe regarding this company. I was reading few days ago, the French financial minister was complaining that this company was potentially blackmailing the French government, by promising to open a factory … Probably you are aware how Huawei got the 5G contract in UK – granting to some UK royalties contracts in China etc.

Not really interested about dealing with Chinese products, still I have some CPUs, MCUs … like Allwinner V3S, ESP32 … if you refund the money I payed for those items, sure, will not bother you with those matters.

Potentially. That's an elusive word.

Any proof from a government certified news agency of any major country?

In my opinion, you are forgetting something. Europe, North America … are not China. There is media censorship, but just look at Daily Mail (https://www.dailymail.co.uk/), The Independent (https://www.independent.co.uk/) … If you insist on “certified proof”, I can inquire the British authorities to initiate a formal investigation how Boris Johnson government granted the 5G contract to Huawei.

It is also interesting the Canadian perspective, one of the lattes: Meng Wanzhou was paying actors to protest at the front of a court … look at the articles at CBC (https://www.cbc.ca/).

@OggyJFX, People pay some times with money that are very hardly earned and expect good products, services and proper financial return. If you do not value and have respect to customers, developers … there are other that do.

I would like to show you one board I recently made. It is modified version of ESP32Controller (https://github.com/simon-jouet/ESP32Controller) for 3D printer/CNC control.

Some can say a Chinese product, except that it was developed by French developers and modified and assembled in Bulgaria. Still the Marlin and ESP3D software support are incomplete, have lots of issues etc. But for open-source work a developer doesn’t get paid, so the developers are not much willing to look at the issues. Potentially the product developers, have to provide some PCBs … for free to other developers etc. Some say that have no intentions about developing something that has poor software quality SDK, availability issues etc. When I ask a Chinese company about free samples, they usually say - no such things in China. On the other hand, let say I invest in this board … who is going to guarantee that some Chinese will not copy the product, dump the price and I will not loose my investments. There are already Chinese copies of DuetWiFi boards (www.duet3d.com) ? Still, the board was developed. In your opinion should it be thrown away ?

By the way I was considering Hi3516EV200 for such usage, but more and more I read your comments, get convinced that I should not deal with Chinese products at all etc.

You do not seem to have proper understanding about the North American engineering regulations, laws etc. When I was in Canada there was created one program for internationally educated engineers, so they can learn those stuff. But have to say to the best of my understanding the Chinese engineering education apparently is not good ...

I like nationalists, I do not like people who pretend to be something they are not. For example I was looking some time ago at some Chinese dressed as ancient Roman members of the parliament. I do not think there were such people. On the other hand, I was looking few days ago a film about Marco Polo. Can you say the Europeans had strong influence during the development of China ?

BBC, IMO is more like documentary, probably you would have to wait a bit …

I doubt that it will, it is a business. Furthermore the communist ideology, it is not yours. You seem to miss the fact that Bulgaria was part of USSR, I lived in those times … Also what communism you talk about ? The Chinese businesses are greedy as hyenas. I was reading recently about a case, a Chinese girl passed away because of hunger, collecting money for his ill brother treatment. The Chinese actually collected the necessary money for the medical treatment, but after the girl’s death and the publicity of the case.

In Canada some say a person have to love what he/she is doing. Why you consider just profit ? The stuff a person works suppose to bring enjoyment etc.

Sure, but as I stated, I am not charity and expect refund of my money including compensations etc. By the way the comment above refers also to all your Chinese junk products … on our markets.

在中国，有一句谚语叫“一分价钱一分货”。比如晕哥买了一辆法拉利，我买了一辆奥拓。我天天就得去找铃木公司，让他们按照给晕哥的服务标准来给我服务，你觉得可能吗？

我尊重和赞赏你的作品。

关于抄袭，说实话，我也很讨厌，每一个开发人员，都会讨厌别人直接抄袭自己的劳动成果，然后直接低价霸占自己的市场。
因为我朋友的产品也被抄袭过，很无语。
目前国内确实有大量开发人员，以抄袭为主，自己懒㤢不上进，这一点我也很痛恨。
不过还好，国内现在已经在加强对知识产权的管理，而且进步很大。

如果真有问题，可以找律师来呀。享受着低成本的方案，然后将所有的脏水沷到中国人头上。
是的，10元的F1C100S，一生下来就有的，是上帝的功劳。然后骂一下快递员，你个罪犯，为什么不将他快点送到我手上。

兄弟，你们那儿现在疫情怎么样啊？那会儿中国封城的时候，全西方都在笑话我们，笑话我们戴口罩。
另外，我还想和你讨论一下，你认为这个病毒的发源地在哪儿？
中国武汉在封城之前，就有500万人离开武汉。去往中国其他地方准备过年，但是中国其他地方感染人数非常少。而武汉封城之前，去往其他国家的，才多少人？那么点儿人就能让全世界引起这么多感染者？500万人离开武汉都没让中国其他地方疫情泛滥，少数人离开武汉去往国外，就把国外整成疫情重灾区了？
用你们西方人高傲的姿态，给我解释一下吧？

Do you have an anticipated OS to run? Linux? XBoot? RTT? Or bare U-Boot?

Just so you know, Tina (the die codename behind F1C series and those non-SiP packages) has very bad documentation. The only things you can find are datasheets and one single user manual that has no explanations on how peripherals work, just a register book and very simplified diagrams and verbiage.

The only practical use of those chips is to wither run AllWinner's own Melis OS or Official (non-GPL-compliant Linux), or to run a third party OS based on drivers stripped and rewritten from Melis or AllWinner Linux.

Put it in other words, see if your application fits one of the existing OSes, and if it does, then great. If not, the chance for an average hobbyist to port a feature to a new OS is virtually zero.

So far, I've been very unwilling to touch Melis or AllWinner Linux as I don't want to step into copyright infringements. I'm only open to FOSS OSes, such as Linux sunxi, XBoot and RTT.

Linux sunxi has all drivers but video encoders/decoders (which was supplied in AllWinner Linux as a blob), but require the longest time to boot and has the most overhead. XBoot has decent support for the chip, but missing some critical ones like USB, also it is not preemptive, so you have to manage all coroutines to make sure they work in synergy.

RTT was great, until it went commercial and stripped graphics support (framebuffer) from Tina BSP (they sell that part now) among many other peripherals. It was neutered to just SPI, UART and libCPU. Unless you do a ton of works, it won't do much other than printing hello world.

So if you are after something like full FreeRTOS support or official FOSS Linux support, this is not your best bet. You only choose this chip if all you need is a powerful SoC with little expanding capability and you are willing to be under the mercy of whatever existing OS you can use.

不是说为了卖柿饼pi官方把图形支持阉了吗？我看最新版的github源码里面驱动只有uart，gpio，spi，mmu，sdio。这几个都是内存卡启动必备的，其他的驱动最新版的驱动是没有的。

我知道旧版的bsp里面有一些东西，但是毕竟官方不支持了，那一天rtt驱动架构改了，或者芯片revise了，就用不了了。

没了已经，至少官方的github仓库里面的tina bsp已经没有了。

大佬nb！

我现在的策略是把XBoot的启动代码和驱动扒出来，然后照着Linux，RTT和FreeRTOS的libcpu自己写一个上下文切换代码，然后自己写一个抢占式调度器替换XBoot的。

XBoot最不方便的就是不支持抢占调度，XBoot的调度器只能从非中断进，所以没法实现从timer ISR抢占。

倒不是说这么搞跟RTT比有什么优势，主要是自从转了电力专业，好久没写代码了，操作系统那些基础都快忘干净了。不赶紧搞个大项目估计技能就废掉了。

最近做了个小手术，今天刚从医院放出来，还要在家静养两周，心里有点长草，总想搞点大新闻。总想不光要改XBoot，更想把XBoot的启动代码和驱动扒出来自己写个RTOS，估计以后能吹一辈子。

这哥们用的是hq的核心板吧,这个核心板的pcb我看过,有点小问题
