[ERROR] on open /dev/xdma_control

[Phoenix0726]

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!
