i.MX93 LVGL how to use PXP rendering

chrishoen — Fri, 01 Nov 2024 14:34:13 GMT

I'm trying to get the LVGL benchmark program for MX93 (LVGL ported to i.MX 93 Evaluation Kit) (https://github.com/lvgl/lv_port_nxp_imx93.git) working so that it uses the PXP gpu for rendering.

In lv_config.h, I set

#define LV_USE_DRAW_PXP 1

and get compile errors:

fatal error: fsl_cache.h: No such file or directory

which are obviously not MX93, but for some NXP microcontroller.

Any advice on where I can go from here is appreciated.

Thanks

Chris

Hi @chrishoen!

Thank you for contacting NXP Support!

The pxp feature is only available on iiMX RTxxx platform.

Best Regards!

Hi Chavira
OK, so do any of the following lvgl selections in CMakeLists.txt: LV_USE_WAYLAND, LV_USE_SDL, LV_USE_DRM actually use the PXP?

HI @chrishoen!

According with our Linux Documentation the GPU 2D works with the PXP Module in iMX93.

The LVGL should run in the GPU 2D that is helped for PXP module.

Best Regards!
