这两天花了不少时间在网上搜索,发现有竞争对普通用户真好!请问Cubieboard A80开发板是否硬件开源? 鉴于各个开发板厂家的技术现状,除价格外,能提供多少硬件相关的资料也应该是选择的重要参考
下面是国外用户使用中国开发板的经验
I have bought many boards from Chinese companies / Solution providers / Factories / Shops / OEMs, none of them provide good technical support.
In most cases..
* The sales girls speaks English and the Engineer speaks only Chinese, the non technical sales girl will have to translate the technical problem to Chinese and back and forth, by then you are tired.
* There is less willingness to support, because there is no money in technical support, Where is the volume order ????
* There is nothing like a open source in China, if you need to do some changes in the hardware, you need to have the schematics / PCB Layout / BOM / Vendor List / SDK / source code / Datasheets of components / English Manuals , In most cases none of the above listed details are complete. if you don’t have some thing it is as good as starting fresh.
* The new products may have many defects / not tested fully / that’s understood but you will not find a document telling what functions are tested and what is not, and what is still under development.
* Many claim it is open source and SDK is available, how about source codes /the SDK is not complete in most cases.
* We will have to depend on the forum for technical support, but then it takes too long time,
* Chip Manufactures –> Solutions Company –> Contract Manufacturer / factory –> Products Company –> retailer / online store . this is the China chain, The Chip manufacture knows the most, but willing to support only multimillion $ deals and hand full of Solutions companies, The Solution company may not have full access to all the source codes, they still have to depend the Chip manufacture. The CM / OEM / Retailer / online store do not have any control or access to technical information other than the rough specifications.
* There is no guarantee that you will get the same product again , the factory would have switched to other products / lead time and price changes with time,
This is just my experience
