IMX8M mini Android9, apk show blank,may be issue by OpenGL2.0

[jhhong]

Hello，We are encountering an OpenGL issue and need some assistance.Thanks!

IMX8M mini Android9, use test apk show blank,may be issue by OpenGL2.0

GPU info:

•Version of OpenGL ES: 2.0 (from DeviceConfigurationInfo)

•Renderer: Vivante GC7000NanoUltr

•Vendor: Vivante Corporation

•Version: OpenGL ES-CM 1.1 (from glGetString(GL_VERSION))

It appears that the imx8m mini can theoretically provide OpenGL ES v2.0, but due to some reasons, it only provides OpenGL ES v1.1 in practice. To support 3D in our software, we need OpenGL ES 2.0.

GPU Renderer and Vendor:

•Renderer: Vivante GC7000NanoUltr

•Vendor: Vivante Corporation

The Vivante GC7000NanoUltra is a GPU that theoretically supports OpenGL ES 2.0 and higher versions. However, in practice, support might be limited due to device driver or firmware settings.

Possible reasons:

1. Outdated or restricted drivers: The GPU drivers may be outdated or restricted by the device manufacturer (as in the case of the imx8m mini), preventing the use of OpenGL ES 2.0 features.

2. Firmware or OS-level restrictions: The device manufacturer may have configured the firmware to disable or make OpenGL ES 2.0 support unavailable.

3. Hardware limitations: While theoretically supporting OpenGL ES 2.0, the actual implementation on your device may be limited to OpenGL ES 1.1.

please help check support why the imx8m mini only provides OpenGL ES v1.1 instead of v2.0, and whether this can be fixed at the software level.

If the OpenGL version issue cannot be resolved on the imx8m mini (as mentioned above), it will limit the tools available to my team for building the application GUI. Perhaps looking into a newer LTS version (for testing in the next order we place) would be reasonable.This is one of the early prototypes of our software on the imx8m mini, running on our sweeper. The GUI is quite basic (no 3D graphics, only a set of PNG images).

Android_Release_Notes.pdf that it does provide OpenGL ES 2.0 support for the i.MX 8M Mini in Android 9. Please confirm which aspect is causing the lack of support.

Hello,

MX8MMini support OpenGLES 2.0 but Android 9 does not include a driver that support it, you need at least android 11 to see opengles 2.0 with MX8MMini.
