[MCX-N9XX-EVK] LCD issue

[bryan_hong]

dear nxp

As you can see in the LCD screen capture below, the output appears abnormal.

According to the document 'lvgl_examples_readme.md' included in the SDK, the MCX-N9XX-EVK is supposed to support the LCD-PAR-S035. Kindly review this issue.

and I use below SDK and project

Thanks,
Bryan

dear Harry

Please let me know once the following action have been completed.

And i also tested the 'mcxn9xxevk_lvgl_guider_bm_cm33_core0'.

It can not work.

I will report it  to our SDK team.

Thanks,

dear Harry

The same result is presented with 'mcxn9xxevk_lvgl_guider_bm_cm33_core0'. Please refer to the image and the link below. Additionally, 'frdmmcxn947_lvgl_demo_benchmark_bm_cm33_core0' also shows the same result. I'm currently testing while modifying 'fsl_st7796s.c'.

It's strange that the example isn't working—are there any clues we should check to investigate further?

Thanks,
Bryan

1. first, you need to download the 2.16 SDK.

Select Board | MCUXpresso SDK Builder
