I am playing with The i.MX 8M Nano EVK board product link with the pre-build Linux image version L5.10.35_2.0.0_MX8MN.
Currently, I have two questions:
1) The technical specification indicates that this board provides GPU features, could you please tell me if the GPU driver or library is already packed into the pre-build Linux image or not? If not, how can I install the GPU driver or library on this board? Because our application runs on the GPU and it's mandatory to us.
2) I tried to run some demo applications under this path but got the following errors, how can I cope with the issue?
drwxr-xr-x 3 root root 4096 Mar 9 2018 ./
drwxr-xr-x 43 root root 4096 Mar 9 2018 ../

ERROR: demo setup failed with: wl_display_connect Failure
Thanks a lot!
