BULK写失败

2万 · 2010-9-26 16:20

68013A端点EP6OUT的BULK写失败求助，急！！
易用专业的PCI、USB、LED方案正在对68013A采用slavefifo方式进行bulk读写操作
我用EP2做in端点，1024字节，2从缓冲
用EP6做OUT端点，512字节，4从缓冲

我写好了68013A的固件，用CYPRESS的开发工具能够进行实现正确的读写
现在正在用DS2.7写驱动，现在写的驱动，能够顺利读取EP2,却不能写入EP6（从SLAVEfifo连接的FPGA端看slavefifo的状态，EP6对应的fifo一直是空的）！

搞固件就郁闷了很久了，好不容易把固件的写搞定，现在驱动又来整我。

一般来说应该不是驱动的问题吧，驱动都是CY编好的应该不会错。

你的代码能贴出来看看呢

楼主是不是端点搞错了,我也使用这个啊,没有出现什么问题啊

因为固件调试工具能够正常进行读写
所以就把问题放在驱动身上
晚上在DS27下把驱动翻了个遍

无果

在DS32下重新开发驱动

效果一样！
