XDMA的驱动是官方提供的,这里不做详细解读,总之XDMA驱动就是把PCIE DMA包成了多种字符设备:xdma_h2c,xdma_c2h,xdma_user,xdma_control,xdma_bypass,xdma_events 经过本人测试使用,我只推荐使用xdma_h2c,xdma_c2h,xdma_bypass,xdma_events这四个字符设备。xdma_h2c用来把数据从内存写到FPGA的DDR,xdma_c2h用来把...

When I read the interrupt signal from /dev/xdma0_events_0, it stuck. A look at the interrupt event file reveals the following error: $cat /dev/xdma0_events_0 cat: /dev/xdma0_events_0: Protocol error I don't know why.
and where is XDMA_EVENT_INT1?? 2.What makes these EVENTs happen?? I thought same as external GPIO Interrupt. but I don't know now.. and How to configure 3. I found Control Module for PIN MUX in AM335x Tech ref manual. and about ( conf_xdma_event_intr0, conf_xdma_event_intr1)...
可以看到,没有 Xilinx 相关的信息,这是因为没有安装 XDMA 的 Linux 系统驱动。 2、驱动安装 下载好的驱动,存放到AGX orin上面 由于提供的都是源码,需要编译安装然后才能使用。打开终端,输入如下命令: cd ./dma_ip_drivers/XDMA/linux-kernel/xdma/ ...
一、XDMA驱动安装 1. 下载XDMA驱动(http://github.com/Xilinx/dma_ip_drivers) 2. 安装XDMA驱动 在命令行中输入lspci,查看系统是否检测到FPGA设备 根据dma_ip_drivers-master/XDMA/linux-kernel/readme.txt文件中的流程完成安装。或者根据网上的安装流程完成安装。XDMA linux平台调试过程记录(http://blog.csdn.net...
