利用FPGA 的灵活性和可扩展性，采用可配置的PCIE 硬核IP 模块以及以太网硬核IP 模块。该系统主要介绍Host PC 与FPGA 之间基于PCIE 2.0的DMA 数据传输以及FPGA 之间基于GMAC 的以太网数据传输，通过PCIe 总线、以太网基于DMA 模块实现数据高速可靠传输。关键词：DWC PCIE Core ；FPGA ；数据传输；DMA 中图分类号：...
初始化与主循环 /* 在PHY初始化后,尤其是RXC输出之后才调用,因为GMAC复位需要RXC */ 使用网口调试工具,发送数据收到后原样返回。 五.总结 LWIP代码移植性非常好,无OS支持也非常好,移植只需要实现平台相关的配置和宏,实现网口收发接口即可。 审核编辑 黄宇...
Add a new glue driver for Rockchip SoCs, i.e RK3568, with a GMAC based on Synopsys DWC Ethernet QoS IP. rk_gmac_ops was ported from linux commit: 3bb3d6b1c195 ("net: stmmac: Add RK3566/RK3568 SoC support") Signed-off-by: Jonas Karlman <jonas@kwiboo.se>...
Hi, We are trying to enable GMAC on the NXP S32G2 RDB2 board, on QNX. However, we are getting the error that the driver (devnp-dwceqos.so) is unable

一般模块都会有软复位的功能,软复位在驱动编写中很重要。一般初始化时执行软复位使得模块进入确定的初始状态以提高可靠性,异常时也可以重新初始化来恢复,所以软复位在驱动中一般是必须要做的动作。对应复杂的IP其复位过程其实是很复杂的,有很多前提和依赖,对于驱动编写来说也有一些需要注意的地方甚至是有一些坑,所以本...
