2、xdma核提供了INTX中断和MSI中断的方式，xilinx官方测试程序也提供了user_event命令来进行中断测试，...
• 操作指令:xdma_rw.exe user write 0x10000 0x11 0x22 小批量用户数据读操作测试: 从BRAM 内存地址 0x10000依次读出两个数据并打印,如下: • 操作指令:xdma_rw.exe user read 0x10000 -l 2 XDMA用户中断测试演示 XDMA用户中断测试为测试用户中断的专用测试软件,如下: • 操作指令:xdma_event.exe 对应...
interrupt_fd= open_event("/dev/xdma0_events_0");//打开用户中断while(work==1) { read_event(interrupt_fd);//获取用户中断int_rc=read_control(control_base,0x00000);//读总中断寄存器switch(int_rc) {case1://接收中断sem_post(∫_sem_rx);break;case2://发送中断txint_rc=read_control(contro...

文件目录分别说明下A. _c2h_x,是card to host的设备,板卡向CPU传输数据的时候使用这个设备;B. _h2c_x,是host to card的设备,CPU向板卡发送数据的时候使用这个设备;C. _control,是XDMA的内部寄存器控制设备,一般用户不需要使用;D. _user,是PCIe to AXI Lite Master Interface选择的空间;E. _event_x,是IP...

2、user是DMA地址空间操作了 3、event 是中断 4、hc2 传输方向主机到开发板 5、c2h 传输方向开发板到...
I`m testing EDMA nowdays. I already success with GPIO_EVENT for EDMA but not xdma_event_intr0~2 somebody knows about this. please let me know. Below is my Question 1.where is [ xdma_event_intr0~2 ]??I`m beaglebone User. and found it in beaglebone schematic ...
