[imx8mp] Kanzi APP Deployment Issues

[HuiQing]

Software Version:

Yocto version : NXP i.MX Release Distro 5.4-zeus

Kernel version : Linux OK8MP 5.4.70-2.3.0-g92a483433-dirty

Wayland version: 1.18.0

GCC version: 9.2.0

Hardware platform:

Soc: MIMX8ML8CVNKZAB ( i.MX8MPQ )

LVDS Screen: 1920*720

Deployment application: Kanzi 3.9.6 Demo program

What is the phenomenon: the screen can not display Kanzi's APP, the screen turns to a black screen from the normal display of Wetson background.

Problem description:

Q1: Why does the GPU driver call /usr/lib/dri/vivante_dri.so?(log line 272)

Q2：In the root filesystem, there are only Open GL ES 2.0 libraries, can updating Open GL ES 3.0 libraries solve the problem?

Q3：How to get and compile Open GL ES 3.0? (Where can I get it from?).

Q4：Do I need to configure wetson?

This is Kanzi's reply on vivante_dri.so："Thanks for the logs. The toolchain we have used to build the Kanzi packages do not contain either vivante_dri. so or vivante_drm.so. Additionally, Kanzi does not refer to any of these binaries directly. It seems like the GPU driver or windowing system is trying to load them. If you think any of these binaries are relevant, then please provide a toolchain that contains these binaries. "

You can go with vivante because We can not reproduce the problem.
