MIMXRT595-EVK cannot bring up RK055AHD091-CTG

[hongfei_hu]

Dear supporter,

We use the MIMXRT595-EVK to connnect RK055AHD091-CTG with 40 pin FPC wire. And We use the example project SDK_2_10_1_EVK-MIMXRT595\boards\evkmimxrt595\vglite_examples\vector_freertos, and change the macro DEMO_PANEL to DEMO_PANEL_RK055AHD091.

I can successfully compile and download the file to hardware board, and can see trace output from serial port, but the screen cannot display anything.

Could you please help me check the issue and provide me the suggestion for next step?

Thanks!

BTW: I use IAR 8.50.9 to build the project

I noticed that for SDK 2.9.1 the document Getting Started with Xplorer for EVK-MIMXRT595.pdf says: 

IAR Embedded Workbench may require a patch to enable compatibility with RT500. Please contact NXP directly about this patch.

Is it the possible root cause? I use IAR 8.50.9 but I donot have the patch. Could you please also help me to get the patch?

Thanks!
