[ERROR] on open /dev/xdma_control #2

你好！ 我在尝试shuhai例程的时候，到了以下这一步： sw -> 4. Application Part -> b. Run HBM testing or DDR4 testing with parameters specified in the "config" file (shown in 3.c). 执行以下命令： $ sudo ./test-hbm --configFile=config.txt 出现了错误： [ERROR] on open /dev/xdma_control

该路径下没有xdma_control这个文件。 请问问题出在哪里？谢谢！

Hello!

When I try the step: sw -> 4. Application Part -> b. Run HBM testing or DDR4 testing with parameters specified in the "config" file (shown in 3.c). $ sudo ./test-hbm --configFile=config.txt

An error occured:

[ERROR] on open /dev/xdma_ control

There is no such file in this path. Could you tell me how to solve this problem? Thank you!

Maybe you should reboot your machine after loading the bitstream, and don't forget to use 'sudo insmod xdma_driver.ko' after reboot.
