[spi-待解决]st7735开机显示后会黑屏,duo v1.0.5版本

背景:
更新代码到最新。
移植st7735后,发现开机时lcd会亮,但是一旦执行到

[ 3.718097] sh (119): drop_caches: 3

之后就会屏幕黑掉,后续log是usb加载。

不清楚是不是usb加载后拉掉了spi的电。

spi配置

&spi2 {
	status = "okay";

	/delete-node/ spidev@0;


	st7789v: st7789v@0{
		compatible = "sitronix,st7789v";
		reg = <0>;
		status = "okay";
	spi-max-frequency = <48000000>;
		spi-cpol;
		spi-cpha;
		rotate = <90>;
		fps = <30>;
		rgb;
		buswidth = <8>;

		//dc-gpios = <&port 21 GPIO_ACTIVE_HIGH>;	//DC
		dc-gpios = <&porta 23 GPIO_ACTIVE_HIGH>;	//DC
		reset-gpios = <&porta 24 GPIO_ACTIVE_HIGH>; //RES
		led-gpios = <&porta 14 GPIO_ACTIVE_HIGH>; //BL

		debug = <0x0>;
	};

};

log如下:

目前看和之前版本的log差在最后的ipv6,但是又是usb之后没有办法显示的。

结合现象和log看,如果usb先起来,那就会让lcd息屏,否则正常。

可以正常显示

Hi,我这边也遇到这个问题,最后发现是启动后自动执行了这个脚本,脚本设置了把ST7735 的背光关闭。
