赛普拉斯 EZ-USB FX CY3671 的替代品
这是一个非常特殊的问题,我不确定 stackoverflow 是否是提出这个问题的正确平台,但我无论如何都会尝试......
我目前正在编写 JSR-80 (javax.usb),刚刚发现有一个可用的测试合规性套件。但该测试合规性套件需要特殊硬件:“Cypress EZ-USB FX 集成电路 Xcelerator 开发套件 CY3671”。 TCK 包含该控制器的固件映像。
问题是:我在任何地方都找不到这个开发板。我只找到不起眼的商店,售价为 800 美元。作为一名开源开发人员,我负担不起。现在的问题是:是否有一些兼容的替代方案?赛普拉斯的后继产品可能与固件兼容,并且更有可能在 eBay 上找到?我在 ebay 上找到了一个“EZ-USB FX2 Board”,价格实惠(50 美元),但我不知道它是否兼容。
This is a pretty special question and I'm not sure if stackoverflow is the right platform to ask it but I try anyway...
I'm currently writing an implementation of JSR-80 (javax.usb) and just found out that there is a Test Compliance Kit available. But this test compliance kit requires special hardware: A "Cypress EZ-USB FX Integrated Circuit Xcelerator Development Kit CY3671". The TCK contains a firmware image for this controller.
The problem is: I can't find this developer board anywhere. I only find obscure shops which sell it for 800 USD. As a Open Source developer I can't afford this. Now the question is: Is there some compatible alternative? A successor from Cypress maybe which is compatible to the firmware and which is more likely to be found on ebay? I found a "EZ-USB FX2 Board" on ebay which is affordable (50 USD) but I have no idea if it is compatible.

FX微控制器是支持USB 1.1标准的产品。现在是 FX2LP 芯片的最后一个版本。
演变为:FX、FX2、FX2LP(符合rohs的芯片)。
FX2/LP 并不与 FX 完全兼容,但它通过 USB 2.0 扩展了其功能,并可能增加数据和程序内存。
如果您有 FX2LP 固件的副本,则在板上下载固件的过程应该完全相同(查找“软配置”和“重新枚举”)。
请参阅此链接了解开发板。
我希望这些信息可以帮助您。
再见
The FX microcontroller was the product that support USB 1.1 standard. Now the last version of the chip in FX2LP.
The evolution is: FX, FX2, FX2LP (rohs compliant chip).
FX2/LP is not completely compatible with an FX, but it extends its capabilities with USB 2.0 and probably increase the data amd program memory.
If you have a copy of a FX2LP firmware, the procedure to download the fw on board should be exactly the same (look for "soft configuration" and "re-enumeration").
Refere to this link for the development boards.
I hope this info could help you.
Bye
我建议联系 JSR 规范负责人 Boyd Dimmock。
JSR80 规范包含她的联系信息
I would suggest contacting the JSR spec lead, Boyd Dimmock.
The JSR80 spec contains her contact information
