Hi @MohamadFares ,
From the document, you can find the SDK code is not the normal MIMXRT1050-EVKB SDK code:
So, you need to download this one:
https://mcuxpresso.nxp.com/en/builder?hw=EVKB-IMXRT1050-AGM01
Please download the correct SDK SDK_2_11_0_EVKB-IMXRT1050-AGM01.zip, Then you can find your needed demo.
Best Regards,
Kerry
