white screen on custom GFX01M2 board

[Dev_P0]

I made a custom STM32 board based on the schematics of Nucleo-G071RB and X-Nucleo-GFX01M2. On the development board, the TFT LCD works. However, when I program my custom board using STLINK-V3SET, the TFT LCD only shows a white screen.

I did changing TFT LCD(DT022CTFT) : new TFT LCD just same.

 

 

this is my custom board's MCU. 

 

 

This is my custom board's SWD pins

 

1. How can I program using STLINK-V3SET in TouchGFXDesigner?

oh.... I forgot DISP-NRESET is not PA1 in my circuit. (X-NUCLEO-GFX01M2's DISP-NRESET is PA1)

I change DISP-NRESET pin to PA4, and working fine
