嗨,各位,
我在解决CYU3PDMALUtiGCHANNEURCOMPIONSORM缓冲区的手动多对一(GPIF到USB)方案中存在一个无效的序列错误。 我已经尝试重置GPIF(通过禁用和启动),重置DMA通道,或者破坏和重新创建DMA通道以及刷新端点。这是我的99%个错误,但在一个情况下,它无济于事。也就是说,我在Cyu3PDMAulultChhannIsPrimeBuffor周期性地出现了一个无效的序列错误,这样我的流就崩溃了。 也许是像HTTP://wwwyCysP.com/FuMU/UB30-Suffely/MalualMytoThan-MulnChurnCurror中的一个缓存返回无效序列,因为我有相当长的一段时间,应用程序不能在前面接收数据,但是我不知道如何检查。是。有没有我可以读出的登记册或财产,我的问题相当于那个主题中描述的问题? 进一步的柏树员工建议恢复流,但这是怎么做的,当没有上述行动的帮助吗? 谢谢和亲切的问候, 朱迪思 以上来自于百度翻译 以下为原文 Hi folks, I'm having problems to resolve an INVALID_SEQUENCE error in a Manual-Many-To-One (GPIF to USB) scenario at CyU3PDmaMultiChannelCommitBuffer. I already tried to reset the GPIF (via Disable and Start), reset the DMA channel or destroy and re-create the DMA channel as well as flushing the Endpoint. This works in 99% of my errors but in one situation it doesn't help. I.e. I have an INVALID_SEQUENCE error at CyU3PDmaMultiChannelCommitBuffer periodically, such that my stream breaks down. Maybe it's a situation like the one described in http://www.cypress.com/forum/u***-30-super-speed/manualmanytoone-multichannelcommitbuffer-returning-invalidsequence as I have a rather long period of time where the application is not able to receive data right before, but I don't know how to check this. Is there any register or property I can read out to be sure, that my problem is equivalent to the one described in that topic? Further the Cypress employee suggests to resume the streaming, but how is this done, when none of the above mentioned actions help? Thanks and kind regards, Judith |

你好,
这个错误通常发生在回流即情况下,到达一个非常快的速度向渠道或如果数据没有足够快的速度处理数据。我希望你使用固件UVC模型作为an75779应用笔记。如果是这样的话,我们建议你使用一个更有效的模型,可以更快速的固件,这个错误是可以避免的过程数据。 请联系柏技术支持修改您的固件基于最近的一个更有效的模型。请提及这个论坛的帖子和回复在技术支持的情况下创建。 当做, - Madhu Sudhan 以上来自于百度翻译 以下为原文 Hi, This error usually occurs in case of backflow i.e, data arriving at a very fast rate to the channel or if the data is not processed fast enough. I hope you are using the UVC Model of firmware as in An75779 application note. If so, we suggest you to use a more efficient model of firmware that can process the data even more faster so that this error is avoided. Please contact the cypress tech Support to modify your firmware based on a recent more efficient model. Please mention about this forum post and my reply in the Tech Support Case you create. Regards, - Madhu Sudhan |
