stm32f469i-disco Applications demo image is not displayed,how to solve？

[ac.2]

I have a stm32f469i-disco board. I compile the stm32f469i-disco demo application st\en.stm32cubef4\STM32Cube_FW_F4_V1.21.0\Projects\STM32469I-Discovery\Applications\STemWin\STemWin_HelloWorld\EWARM, Compiled successfully and downloaded to the development board, the LED blinking instructions program is running, but the LCD does not display any text or graphics. But I use st-link utility to download STM32469I-Disco_Demo_V1.2.0_FULL.hex, which was pre-compiled in STM32CUBE-FW, directly. The development board can display pictures and text when the download is successful. So I can exclude hardware circuit problems. Who can give me a hint, why I compiled APP demo with IAR and downloaded to the development board, can not display graphics, text and pictures？Thanks a lot!

Hello,

Which IAR version are you using ?

If you are using an older IAR version, please try to switch to the latest one.

Please, keep us informed about your progress.
