Hi @NXTyam ,
Thank you so much for your interest in our products and for using our community.
Please check your MIMXRT1170-EVKB development board settings:
1: Is the RK055AHD091 screen correctly connected to the J48 of the MIMXRT1170-EVKB development board?
2: Is 5V power connected to MIMXRT1170-EVKB J43, and is J38 set to 1-2?
Have you successfully run GUI Guider project before? I suggest confirming your hardware development environment and then trying to run the simplest demo again.
Wish it helps you.
If you still have question about it, please kindly let me know.
Best Regards
MayLiu
