axi dma 例子 Axi DMA(Direct Memory Access)是一种用于在外设和内存之间进行高速数据传输的技术。它允许外设(如网络接口卡、存储控制器等)直接访问系统内存,而无需CPU的干预,从而提高数据传输效率和系统整体性能。 下面举一个简单的例子来说明Axi DMA的工作原理。假设我们有一个系统,其中包含一个FPGA(Field-...
On the PS side, I detect this signal and control a state machine in the PL side to read the RAM and convert the data into AXI Stream interface format, storing it in a Stream Data FIFO with a depth of 8192 bytes. Once all the data is stored in the FIFO, I execute the XAxiDma_...
Hi Brandon, I'm trying to use your driver on a zedboard, petalinux system.When i run insmod axidma.ko command to load driver,the error in the title comes up. This is the error log: root@dmaTest:/lib/modules/4.6.0-xilinx/extra# insmod axi...
Greetings, I have a question about the AXI DMA, which I cannot answer clearly from reading PG021. Maybe someone here in the forum can help point me in the right direction? Connection setup: (AXI4-S
Hi Brandon, I send data from PS to the PL side by "axidma_oneway_transfer()", then the PS side process do nothing but waitting for an interrupt generate by gpio ip core in PL side, which indicate the data just send from the PS side have ...

The AXI4 master interfaces of the axi_dma have been connected to the HP0 port of the PS. This connection could be easily changed to the PS ACP port. If the design is changed to the ACP port, make sure that the option 'Use slave driven AxUSER values' is not checked in the ACP con...

Hi,I tried implementing AXI DMA as explained here: https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/1027702787/Linux+DMA+From+User+Space+2.0 I did the same as the prototype (the 1st one) but without the use of system coherency and
