基本问题

1. 屏幕参数

将 rk_lcd_parameters 放入 FAT32 U盘

注意: 公版固件需要 1.0.20 以上才可支持 pwm-polarity = 1; 参数

# 屏幕类型 - DC690仅支持[0 - DSI0,2 - edp0]
# 0 - DSI0 ; 1 - DSI1 ; 2-edp0 ; 3-edp1 ; 4-rgb
panel-type = 2;

# panel info
#unprepare-delay-ms = 100;
#enable-delay-ms = 100;
#disable-delay-ms = 100;
#prepare-delay-ms = 100;
#reset-delay-ms = 100;
#init-delay-ms = 100;
#width-mm = 0;
#height-mm = 24;

# panel timing
clock-frequency = 533000000;
hactive = 3840;
hfront-porch = 80;       
hsync-len = 20;
hback-porch = 80;
vactive = 2160;
vfront-porch = 30;
vsync-len = 10;
vback-porch = 30;
hsync-active = 0;
vsync-active = 0;
de-active = 0;
pixelclk-active = 0;
pwm-polarity = 1;

#clock-frequency = 72000000;
