某些嵌入式系统需要在Bootloader中驱动网卡完成特定的网络功能。本文针对嵌入式 系统存储容量有限的特点,提出了PCIe类网卡简化驱动模型,并给出一个具体实现。对于嵌入式系统Bootloader下的网卡驱动开发有一定的借鉴作用。 关键词:PCI Express(周边原件高速扩展接口);嵌入式系统;网卡驱动 Abstract:Some embedded systems need to drive the NIC to complete some network functions. According to the limited storage capacity in embedded systems, this article presents a simplification model for PCIe NICs, and gives an implementation. This will have some reference value for NIC driver design in embedded Bootloader. 【Key Words】PCIe;embedded system;NIC driver
