NXP Zephyr display portability Demo Issue

[castro0327]

@dereksnell,

I am having a difficult time trying to run that example that @derek provided for the FRDM-RW612 development board where we can just flash an example from from the lvgl folder that zephyr has provided. 

west build -b frdm_rw612 --shield lcd_par_s035_spi samples/modules/lvgl/demos --pristine
west flash

Running this commands just makes the screen lots of little colors with no actual display or graphics. I also tried running the other example in that video with no luck as well, and made sure to make the proper adjustments to the dip switches. Do I have be running the latest zephyr for this work?  I am confused what I did wrong. Let me know if I can provide anymore information to potentially help, I just received this dev board and lcd in the mail a few days ago, so I can't see the hardware being the problem. 
NXP Zephyr display portability demo  Is the example I am referring to.

Hello @castro0327, hope you are doing well.

I have just tested the example and it is working properly, please see below my environment setup for your reference:

• MCUXpresso for VS Code (should work with west commands either).
• Zephyr v4.3.0
• Zephyr SDK v0.17.4
• FRDM-RW612

I see that the guide is using the latest Zephyr version, therefore I would suggest that you try it with that guide and make sure that you have the latest Zephyr SDK version (0.17.4) when building and flashing the example.

Please let me know if this helps.
