Hello, my development board is IMX7Dsabresd. When I drive my screen through the RGB signal on the development board, I found that the polarity of HSYNC and VSYNC output from the development board is opposite to the polarity required by my screen. How can I change it? The polarity of HSYNC and VSYNC.
This is the waveform of the vsync measured by my IMX7D development board.
My LCD driver file is using...\git\drivers\video\fbdev\mxsfb.c
What should I modify so that the waveforms of HSYNC and VSYNC match the requirements of my screen.
