不能从FIFO引脚获得输出数据

在TRM的第32页中显示12个可能的端点配置。你在跟踪这个吗？



以下为原文
In page 32 of the trm the 12 possible endpoint configurations is displayed. Are you following this?

对。当EP8被输出时，我们已经使用了第十一个融合（EP2 1024×3，EP8×512×2）。和第一配置（EP2 512×2，EP8 512×2），当输出EP2时。



以下为原文
Yes. We have used the 11th conifguration (ep2 1024 x 3, ep8 512 x 2), when ep8 was output. And the first configuration (ep2 512 x 2, ep8 512 x 2), when ep2 was output.

我来看看我能不能测试一下你所描述的…我记得EP8工作得很好…



以下为原文
I'll see if i can test what you are describing... i remember ep8 working fine...
