The present invention discloses a FPGA-based PCIE bus bridge interface, a CPU module, a CPU module is connected via the PCIE bus and programmable chip, coupled to a different programmable chip through the bus and the corresponding external device, the pull-up resistor provided on the adjustment...
PCI总线,指的就是PCI Local Bus。 先来看一下PCI Local Bus的系统架构图: 从图中看,与PCI总线相关的模块包括: Host Bridge,比如PC中常见的North Bridge(北桥)。图中处理器、Cache、内存子系统通过Host Bridge连接到PCI上,Host Bridge管理PCI总线域,是联系处理器和PCI设备的桥梁,完成处理器与PCI设备间的数据...
This section describes how to configure the userBaseConfig and DTB files for the PCIe interface based on a mother board that is different from the Atlas 200I DK A2 developer kit and Atlas 500 A2 edge station. Prerequisites You have obtained the board ID of the device. 33150 is used here ...
The PCIe interface is defined in the i.MX6 CPU, ConnectCore 6, and ConnectCore 6 SBC device tree files. Example: PCIe Definition of the bus Common ConnectCore 6 device tree pcie: pcie@1ffc000 { compatible = "fsl,imx6q-pcie", "snps,dw-pcie"; reg = <0x01ffc000 0x04000>, <0x01...
chip0_strategy 0~n。 策略索引号。对应代码中的sub_strategy0和sub_strategy1。 max_power 0表示20T。 2表示8T。 最大算力档位。 euqal 0-n。 匹配DTB时等效board_id使用,保持默认配置0即可。 第二处加粗字体修改为用户产品的实际SerDes配置,具体规则如下: PCIe控制器0(lane0~lane1)支持RC/EP...
