IDT InterpriseTM Integrated Communications Processor-79RC32435

flex_zhang

The 79RC32435 is a member of the IDT™ Interprise™ family of PCI integrated communications processors. It incorporates a high performance cpu core and a number of on-chip peripherals. The integrated processor is designed to transfer information from I/O modules to main memory with minimal CPU intervention, using a highly sophisticated direct memory access (DMA) engine. All data transfers through the RC32435 are achieved by writing data from an on-chip I/O peripheral to main memory and then out to another I/O module.

我用的是RC32438，碰到一个问题，使能PCI接口，挂载USB驱动后，访问PCI空间，有时会吊死系统。PCI上只有USB设备发起的到CPU Memory的访问，但都以Retry结束，现象跟设置TNR位后很类似。不知各位有没有类似经历。请给些建议。谢谢了。
