xdma windows driver dma (h2c write and c2h read operations cannot be completed).

Write the zynq 7035 bitstream file and the fsbl.elf generated bin file to the sd card. Power off and restart, run xdma_info again to find the device (user, h2c, c2h), sdk can run normally. But running h2c write, or c2h read program stuck, can not be completed (DMA operation can not be performed). I have to restart the computer (no power off), or uninstall the driver and reinstall it to read it normally.

Hi @xumoxiao,

are you using windows7 or window10? have you selected correct version of the drivers for the OS you during install?

which version of the Vivado tool you are using?

The pc system uses the win10 1809 version, the driver uses the src_18_2 version, and the vivado uses the 2018.3 version.What is the problem?

can you provide the XDMA IP settings and also can you post the log (messages) you see after you run the test example before the hang.

The above picture is to write h2c 4byte addr 0x00 operation, the execution can not be completed.

Read and write user channel execution can be completed.The axi-mem interface of xdma is not 1 and awready is 1.

Attachment cannot add XCI
